This data set, from DS 90-A, Gulf Coast Geology (GCG) Online—Miocene of Southern Louisiana by A. Curtis Huffman, Jr., Scott A. Kinney, Laura R.H. Biewick, Heather R. Mitchell, and Gregory L. Gunther, provides a comprehensive overview of various geological features and resources within the Gulf Coast region, including base geology, seismic lines, anticlines, orogenic belts, fault zones, and volcanic provinces. The base geology layers, derived from maps and figures published by the Geological Society of America, form the foundational framework for regional geological analysis, with key data digitized from paper maps. Seismic lines used by the USGS in resource assessment, along with detailed mappings of faults, salt limits, and diapirs, are included. The set also covers Southern Louisiana, detailing oil and gas wells, fields, and producing areas, with data accessible through the Louisiana Department of Natural Resources SONRIS database. Contouring data, derived from biostratigraphic data and EarthVision modeling, provides insights into structural and thickness variations, while depositional systems offer detailed representations of Lower and Middle Miocene sequences. Finally, geographic and cultural layers, along with petroleum province outlines, are included for location and context. Each of the child layers below contain additional details about data sources and formatting.
