The geologic and mineral resource information shown on this map is derived from digitization of the original data from Abdullah and Chmyriov (1977) and Abdullah and others (1977). The U.S. Geological Survey (USGS) has made no attempt to modify original geologic map-unit boundaries and faults. However, modifications to map-unit symbology and minor modifications to map-unit descriptions have been made to clarify lithostratigraphy and to modernize terminology. The classification of mineral deposit types is based on interpretation of existing descriptive information and on limited field investigations by the authors. Deposit-type nomenclature used for nonfuel minerals is modified from published USGS deposit-model classifications, as compiled in Stoeser and Heran (2000). New petroleum sites are based on research of archival data by the authors and shaded-relief base is derived from Shuttle Radar Topography Mission digital elevation model data having 85-meter resolution.
