The McGinness Hills geothermal system lies in a ~8.5 km wide, north-northeast trending accommodation zone defined by east-dipping normal faults bounding the Toiyabe Range to the west and west-dipping normal faults bounding the Simpson Park Mountains to the east. Within this broad accommodation zone lies a fault step-over defined by north-northeast striking, west-dipping normal faults which step to the left at roughly the latitude of the McGinness Hills geothermal system. The McGinness Hills 3D model consists of 9 geologic units and 41 faults. The basal geologic units are metasediments of the Ordovician Valmy and Vininni Formations (undifferentiated in the model) which are intruded by Jurassic granitic rocks. Unconformably overlying is a ~100s m-thick section of Tertiary andesitic lava flows and four Oligocene-to-Miocene ash-flow tuffs: The Rattlesnake Canyon Tuff, tuff of Sutcliffe, the Cambell Creek Tuff and the Nine Hill tuff. Overlying are sequences of pre-to-syn-extensional Quaternary alluvium and post-extensional Quaternary alluvium. 10-15 degrees eastward dip of the Tertiary stratigraphy is controlled by the predominant west-dipping fault set. Geothermal production comes from two west dipping normal faults in the northern limb of the step over. Injection is into west dipping faults in the southern limb of the step over. Production and injection sites are in hydrologic communication, but at a deep level, as the northwest striking fault that links the southern and northern limbs of the step-over has no permeability.

The Neal Hot Springs geothermal system lies in a left-step in a north-striking, west-dipping normal fault system, consisting of the Neal Fault to the south and the Sugarloaf Butte Fault to the north (Edwards, 2013). The Neal Hot Springs 3D geologic model consists of 104 faults and 13 stratigraphic units. The stratigraphy is sub-horizontal to dipping

The San Emidio geothermal system is characterized by a left-step in a west-dipping normal fault system that bounds the western side of the Lake Range. The 3D geologic model consists of 5 geologic units and 55 faults. Overlying Jurrassic-Triassic metasedimentary basement is a ~500 m-1000 m thick section of the Miocene lower Pyramid sequence, pre- syn-extensional Quaternary sedimentary rocks and post-extensional Quaternary rocks. 15-30 degrees eastward dip of the stratigraphy is controlled by the predominant west-dipping fault set. Both geothermal production and injection are concentrated north of the step over in an area of closely spaced west dipping normal faults.

The Tuscarora geothermal system sits within a ~15 km wide left-step in a major west-dipping range-bounding normal fault system. The step over is defined by the Independence Mountains fault zone and the Bull Runs Mountains fault zone which overlap along strike. Strain is transferred between these major fault segments via and array of northerly striking normal faults with offsets of 10s to 100s of meters and strike lengths of less than 5 km. These faults within the step over are one to two orders of magnitude smaller than the range-bounding fault zones between which they reside. Faults within the broad step define an anticlinal accommodation zone wherein east-dipping faults mainly occupy western half of the accommodation zone and west-dipping faults lie in the eastern half of the accommodation zone. The 3D model of Tuscarora encompasses 70 small-offset normal faults that define the accommodation zone and a portion of the Independence Mountains fault zone, which dips beneath the geothermal field. The geothermal system resides in the axial part of the accommodation, straddling the two fault dip domains. The Tuscarora 3D geologic model consists of 10 stratigraphic units. Unconsolidated Quaternary alluvium has eroded down into bedrock units, the youngest and stratigraphically highest bedrock units are middle Miocene rhyolite and dacite flows regionally correlated with the Jarbidge Rhyolite and modeled with uniform cumulative thickness of ~350 m. Underlying these lava flows are Eocene volcanic rocks of the Big Cottonwood Canyon caldera. These units are modeled as intracaldera deposits, including domes, flows, and thick ash deposits that change in thickness and locally pinch out. The Paleozoic basement of consists metasedimenary and metavolcanic rocks, dominated by argillite, siltstone, limestone, quartzite, and metabasalt of the Schoonover and Snow Canyon Formations. Paleozoic formations are lumped in a single basement unit in the model. Fault blocks in the eastern portion of the model are tilted 5-30 degrees toward the Independence Mountains fault zone. Fault blocks in the western portion of the model are tilted toward steeply east-dipping normal faults. These opposing fault block dips define a shallow extensional anticline. Geothermal production is from 4 closely-spaced wells, that exploit a west-dipping, NNE-striking fault zone near the axial part of the accommodation zone.

This report presents the geologic framework critical in understanding spring discharge and the hydrogeology in Black Canyon directly south of Lake Mead below Hoover Dam, Nevada and Arizona. Most of the springs are thermal 2 Geologic Framework of Thermal Springs, Black Canyon, Nevada and Arizona with temperatures as much as 45 degrees C. This study is part of a hydrogeologic and geochemical study of the Black Canyon thermal springs by the U.S. Geological Survey, funded by the National Park Service and National Cooperative Geologic Mapping Program of the U.S. Geological Survey. The study consisted of (1) compilation of existing geologic mapping, augmented by new field geologic mapping and geochronology (Felger and others, 2014), (2) collection and analysis of structural data adjacent to the springs of interest (appendix 1; Anderson and Beard, 2011; Beard and others, 2011a), and (3) construction of regional cross sections (pl. 1). The most significant results identify faults, fracture zones, and rock characteristics that influence the hydrogeology of Black Canyon. Additional results include refinement of the volcanic stratigraphy based on field mapping and new geochronology. This report will be integrated into a companion hydrogeologic report that includes new geochemical and spring flow data that describes groundwater components of Black Canyon thermal springs (M. Moran, written commun, 2013).

The Pliocene to lower Pleistocene Ancha Formation, upper Santa Fe Group, is a relatively coarse deposit found south and west of Santa Fe, northern New Mexico. It extends southward from the downdropped southern Española Basin of the Rio Grande rift onto a weakly faulted structural platform that extends to the Rio Galisteo, a distance of approximately 30 km (19 mi). The Ancha Formation is found as far west as the La Bajada escarpment (also ~30 km distance). The Ancha Formation is texturally variable but predominately a sand to gravelly sand, with clayey-silty, fine-grained sand increasing towards the southwest. Examination of well logs indicates that the lower part of the Ancha Formation is commonly gravelly. Due in part to its relative coarseness, the Ancha Formation forms a locally important shallow aquifer for the Santa Fe area. The characteristics of the formation’s base and its thickness are important to regional groundwater studies and are also useful for other studies involving basin stratigraphy, structure, geophysical interpretations, and basin evolution. The base of the Ancha Formation coincides with a Pliocene erosional surface overlying tilted and faulted beds of the Tesuque Formation (upper Oligocene-upper Miocene), the Espinaso Formation (upper Eocene to lower Oligocene), the Galisteo Formation (Eocene), and, locally, older Mesozoic and Paleozoic units. In order to characterize the thickness and the basal contact of the Ancha Formation, three data sets were evaluated: (1) cuttings and geophysical logs of key exploration drill holes and water wells, including monitoring wells; (2) lower resolution, generalized lithologic logs from water wells; and (3) outcrop exposures of the basal contact. This report presents the latest lithologic, thickness, and hydrologic observations for the Ancha Formation in the Santa Fe embayment in the form of four map plates: (1) Plate 1, elevation contour map of the base of the Ancha Formation; (2) Plate 2, isopach map showing thickness of the Ancha Formation; (3) Plate 3, saturated thickness of the Ancha Formation (2000 to 2005 conditions); and (4) Plate 4, subcrop geologic map showing distribution of strata underlying the Ancha Formation. Supporting data are presented in five tables.

Maps are presented which show indices of organic diagenesis, and form part of a data base which includes previously published stratigraphic and structural data for assessing hydrocarbon potential in the Appalachian and structural data for assessing hydrocarbon potential in the Appalachian basin (de Witt, 1975; de Witt and others, 1975; Harris, 1975; Miller, 1975). The potential for oil and gas production in any basin depends on the presence of source beds, favorable hydrocarbon channelways, and structural and stratigraphic traps. Crucial to these factors is the level of organic diagenesis or thermal maturity within the basin. Numerous studies have shown that depth and duration of burial and geothermal gradient (time and temperature) are the chief elements producing organic diagenesis.

From the site: "The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The Assessment Unit boundary is defined geologically as the limits of the geologic elements that define the Assessment Unit, such as limits of reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are Assessment Units that border the Federal-State water boundary. In these cases, the Federal-State water boundary forms part of the Assessment Unit boundary."

From the site: "Cell maps for each oil and gas assessment unit were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry, or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were developed as a graphic solution to overcome the problem of displaying proprietary PI/Dwights PLUS Well Data. No proprietary data are displayed or included in the cell maps. The data from PI/Dwights PLUS Well Data were current as of October 2001 when the cell maps were created in 2002."

This collection of data has been assembled as part of the site characterization data used to develop the conceptual geologic model for the Snake River Plain site in Idaho, as part of phase 1 of the Frontier Observatory for Research in Geothermal Energy (FORGE) initiative. They were assembled by the Snake River Geothermal Consortium (SRGC), a team of collaborators that includes members from national laboratories, universities, industry, and federal agencies, lead by the Idaho National Laboratory (INL).

As part of the Midwest Regional Carbon Sequestration Partnership (MRCSP)’s regional characterization project, the Ohio Department of Natural Resources, Division of Geological Survey evaluated the structure of nine formations in the Appalachian Basin of Ohio to assess seal integrity and whether carbon dioxide (CO2) migration pathways could pose a potential risk.

Detailed geologic mapping (1:24,000 scale), structural and geochemical analyses, and integration of available geophysical and well-field data were utilized to assess the structural controls of the Neal Hot Springs geothermal field in eastern Oregon. The geothermal field lies within the intersection of two regional grabens, the middle-late Miocene, north-trending, Oregon-Idaho graben and younger late Miocene to Holocene, northwest-trending, western Snake River Plain graben. It is marked by Neal Hot Springs, which effuse from opaline sinter mounds just north of Bully Creek. Production and injection wells, with temperatures up to 142 degrees C, intersect the Neal fault zone at depths of 680-1900 m and subsidiary faults within a relay ramp or step-over within the fault zone. The stratigraphy at Neal correlates with four regional packages. Basement rocks, discovered in one well, are granite, tentatively correlated with Jurassic Olds Ferry-Izee terrane. Nonconformably above is a thick package of middle Miocene Columbia River Basalt Group lavas, regionally known as the basalt of Malheur Gorge. Conformably above are middle to late Miocene Oregon-Idaho graben lavas, volcaniclastics, fluvial and lacustrine rocks. Overlying are the youngest rocks at Neal, which are late Miocene to Pliocene, western Snake River Plain lacustrine, fluvial, and volcaniclastic rocks. The structural framework at Neal is characterized by northerly to northweststriking normal faults, including the geothermally related Neal fault zone. Stress inversion of kinematic data reveal an extensional stress regime, including an interpreted younger, southwest-trending (~243 degrees), least principal stress and an older, west-trending (~265 degrees) least principal stress. The geothermal field is bounded on the east by the Neal fault, a major, westdipping, north-northwest-striking, steeply dipping normal to oblique-slip fault, along which geothermal fluids ascend, and on the west by the concealed north-northweststriking, west-dipping Sugarloaf Butte fault. The Neal fault zone can be modeled into two structural settings: an interpreted older, left-stepping, normal-slip fault zone and a younger, oblique sinistral-normal zone, suggested by the earlier west-trending and later southwest-trending extensional stress regimes. Recent sinistral-normal displacement may have generated a small pull-apart basin in the Neal area and facilitated development of the geothermal system. 'Hard-linkage' between the Neal and Sugarloaf Butte faults occurs through concealed, west-northwest-striking faults, including the Cottonwood Creek subvertical fault, along which lateral fluid-flow is likely. An inferred northplunging fault intersection at the Neal Hot Springs likely controls the location of the hot springs and sinter terraces. Young structural features are evident at Neal. The Neal fault zone cuts Quaternary fans and late Miocene lower and upper Bully Creek Formation sedimentary rocks. In addition, the geothermal field is 4 km west of the active, north- to northweststriking, normal-slip Cottonwood Mountain fault. Furthermore, the field is within several kilometers of recently detected seismicity. This, coupled with its active hot springs (~90 degrees C), opaline sinter mounds, and geothermal fluid flow, suggest that the geothermal field lies within an active (Quaternary), southward-terminating, left-stepping fault zone, which locally acts as a pull-apart basin with sinistral- and normal-slip components.

Detailed geologic mapping, structural analysis, and well data have been integrated to elucidate the stratigraphic framework and structural setting of the Tuscarora geothermal area. Tuscarora is an amagmatic geothermal system that lies in the northern part of the Basin and Range province, ~15 km southeast of the Snake River Plain and ~90 km northwest of Elko, Nevada. The Tuscarora area is dominated by late Eocene to middle Miocene volcanic and sedimentary rocks, all overlying Paleozoic metasedimentary rocks. A geothermal power plant was constructed in 2011 and currently produces 18 MWe from an ~170 degrees C reservoir in metasedimentary rocks at a depth of ~1430 m. Analysis of drill core reveals that the subsurface geology is dominated to depths of ~700-1000 m by intracaldera deposits of the Eocene Big Cottonwood Canyon caldera, including blocks of basement-derived megabreccia. Furthermore, the Tertiary-Paleozoic nonconformity within the geothermal field has been recognized as the margin of this Eocene caldera. Structural relations combined with geochronologic data from previous studies indicate that Tuscarora has undergone extension since the late Eocene, with significant extension in the late Miocene-Pliocene to early Pleistocene. Kinematic analysis of fault slip data reveal an east-west-trending least principal paleostress direction, which probably reflects an earlier episode of Miocene extension. Two distinct structural settings at different scales appear to control the geothermal field. The regional structural setting is a 10-km wide complexly faulted left step or relay ramp in the west-dipping range-bounding Independence-Bull Run Mountains normal fault system. Geothermal activity occurs within the step-over where sets of east- and west-dipping normal faults overlap in a northerly trending accommodation zone. The distribution of hot wells and hydrothermal surface features, including boiling springs, fumaroles, and siliceous sinter, indicate that the geothermal system is restricted to the narrow (< 1 km) axial part of the accommodation zone, where permeability is maintained at depth around complex fault intersections. Shallow up-flow appears to be focused along several closely spaced steeply west-dipping north-northeast-striking normal faults within the axial part of the accommodation zone. These faults are favorably oriented for extension and fluid flow under the present-day northwest-trending regional extension direction indicated by previous studies of GPS geodetic data, earthquake focal mechanisms, and kinematic data from late Quaternary faults. The recognition of the axial part of an accommodation zone as a favorable structural setting for geothermal activity may be a useful exploration tool for development of drilling targets in extensional terranes, as well as for developing geologic models of known geothermal fields. Preliminary analysis of broad step-overs similar to Tuscarora reveals that geothermal activity occurs in a variety of subsidiary structural settings within these regions. In addition, the presence of several high-temperature systems in northeastern Nevada demonstrates the viability of electrical-grade geothermal activity in this region despite low present-day strain rates as indicated by GPS geodetic data. Geothermal exploration potential in northeastern Nevada may therefore be higher than previously recognized.

Shapefiles and spreadsheets of structural data, including attitudes of faults and strata and slip orientations of faults. - Detailed geologic mapping of ~30 km2 was completed in the vicinity of the Columbus Marsh geothermal field to obtain critical structural data that would elucidate the structural controls of this field. - Documenting E- to ENE-striking left lateral faults and N- to NNE-striking normal faults. - Some faults cut Quaternary basalts. - This field appears to occupy a displacement transfer zone near the eastern end of a system of left-lateral faults. ENE-striking sinistral faults diffuse into a system of N- to NNE-striking normal faults within the displacement transfer zone. - Columbus Marsh therefore corresponds to an area of enhanced extension and contains a nexus of fault intersections, both conducive for geothermal activity.

This is a digitized geologic map, in shapefile format, including rock unit lithological descriptions, faults, and dikes.

Paper discussing the geology of the Devonian shales and the potential locations of gasses within it. From the paper: "The internal stratigraphy of almost any sedimentary resource – be it a coal bed, an evaporite, or an aging oil field programmed for secondary recovery - is a vital first step for evaluating its full resource potential. Because this is also true of the gas potential of the Upper Devonian black-shale sequence of the Appalachian basin, we have identified and named a useful marker bed, the Three Lick Bed, in the upper part of the Ohio Shale and its equivalents in eastern Kentucky and in nearby Ohio, West Virginia, and Tennessee. The Three Lick Bed consists of three greenish-gray shale beds separated by fissile, brownish-black shale. These distinctive greenish gray shale beds are easily recognized in outcrop in seven sections on the east flank of the Cincinnati arch from southern Ohio into Tennessee, have a distinctive signature on wire-line logs, and can be identified in well cuttings over much of eastern Kentucky and adjacent parts of Ohio and West Virginia. The Three Lick Bed correlates with the middle unit of the Gassaway Member of the Chattanooga Shale in Tennessee and with the lower part of the Camp Run Member of the New Albany Shale in Indiana."

Western Gas Sands Project-Stratigraphy of the Piceance Basin

A stratigraphic cross section of the Williston Basin

Five earth models were generated in SEAM Phase I to simulate a realistic earth model of a salt canopy region of the Gulf of Mexico complete with fine-scale stratigraphy that includes oil and gas reservoirs. The model represents a 35 km EW x 40 km NS area and 15 km deep. The grid interval for the Elastic Earth model is 20 m x 20 m x 10 m (x,y,z). All model properties are derived from fundamental rock properties including v-shale (volume of shale) and porosities for sand and shale that follow typical compaction gradients below water bottom. Hence, properties have subtle contrasts at macro-layer boundaries, especially in the shallow section, generating very realistic synthetic data. The Elastic Earth Model distribution is the model used for simulation of the SEAM Phase I RPSEA elastic data set. For the simulations, the minimum S-wave velocity was set at 600 m/s by compressing all S-wave velocities in the originally designed model having velocities between 100 and 800 m/s into a range between 600 and 800 m/s. This distribution has 3 binary files, one each for the density, P-wave velocity and the S-wave velocity. A README is also included.
