United States Geological Survey 2004 Downloadable GIS Data Reston,VA U.S. Geological Survey, Central Energy Resources Team Huffman, A.C., Kinney, S.A., Biewick, L.R.H., Mitchell, H.R., Gunther, G.L. 2004 Applications U.S. Geological Survey Data Series DS-90-A, version 1.0 Denver, Colorado U.S. Geological Survey, Central Energy Resources Team https://pubs.usgs.gov/ds/2004/90/A/ https://doi.org/10.5066/P9P53TY5 The maximum extent of Cretaceous onlap is generalized from Plate 3, Structure at the base and subcrop below Mesozoic marine section, Gulf of Mexico Basin (compiled by A. Salvador) in Volume J, The Geology of North America (1991). This dataset contains basic data and interpretations developed and compiled by the U.S. Geological Survey's Framework Studies and Assessment of the Gulf Coast Project. Other major sources of data include publicly available information from state agencies as well as publications of the U.S. Geological Survey and other scientific organizations. In cases where company proprietary data were used to produce various derivatives such as contour surfaces, the source is cited but the data are not displayed. The dataset was developed primarily to facilitate the synthesis and analysis of various data types required in the assessment of energy resources and to aid in the study and visualization of framework elements and processes. In addition the dataset provides access to the information in an easily usable format for those outside of the USGS. 2004 publication date Complete As needed -103.130700 -80.599143 37.297274 30.280354 None Miocene Gulf Coast Framework Studies Geology Anticlines Gateway to the Earth draft 9 28-Jun-2002 Oil sand resources Coalbed methane resources Natural gas resources Economic geology ArcIMS Metadata Server Theme Codes geoscientificInformation economy Central Energy Resources Team Energy Resources Earth Science Natural Resources U.S. Geological Survey USGS Geology Oil Natural Gas Petroleum Coalbed Methane Coal Resource Assessment Tertiary Systems EnergyResourceActivities oilgas gulfroom gulfcoastframework None Gulf Coast Gulf of Mexico AL TX MS LA FL AR United States USGS Energy Resource Regions (NOGA-95) Gulf Coast Augmented FIPS 10-4 and FIPS 6-4, version 1.0 US01 = Alabama US05 = Arkansas US12 = Florida US22 = Louisiana US28 = Mississippi US48 = Texas USGS Oil and Gas Provinces (NOGA-95) 50 = Florida Peninsula 49 = Louisiana-Mississippi Salt Basins 48 = East Texas Basin 47 = Western Gulf USGS Metadata Identifier USGS:60a6bc7dd34ea221ce4ba9a2 none none U.S. Geological Survey - CERSC Data Management Services Project mailing and physical

J, pl. 3). GSA, GNA, v. J, pl. 3, represents the structure at the base and subcrop below the Mesozoic marine section, Gulf of Mexico Basin. It is assumed that the map that represents the structure at the base and subcrop below the Mesozoic marine section, Gulf of Mexico Basin is complete, and therefore, the Cretaceous onlap is complete.
