EDX is the Department of Energy (DOE)/Fossil Energy Carbon Management (FECM) virtual library and data laboratory built to find, connect, curate, use and re-use data to advance fossil energy and environmental R&D. Developed and maintained by the National Energy Technology Laboratory (NETL), EDX supports the entire life cycle of data by offering secure, private collaborative workspaces for ongoing research projects until they mature and become catalogued, curated, and published. EDX adheres to DOE Cyber policies as well as domestic and international standards for data curation and citation. This ensures data products pushed public via EDX are afforded a citation for proper accreditation and complies with journal publication requirements.

From the abstract: Much has been written about the buried Nemaha uplift in Kansas and Oklahoma since drillers and geologists first became aware of it from oil-well drilling in the early years of the twentieth century. It has been described as extensional, compressional, and strike-slip. In this paper I will present data to show that the Nemaha was formed by compressional or thrust faulting that is rooted deep within the Precambrian crust and extended in listric fashion to the ground surface coincident with the Humboldt fault zone, or east-bounding fault. Compressional effects observed from well data and seismic surveys do not permit an extensional origin.
