The STATEMAP program is a cooperative effort between the U.S. Geological Survey and State Geological Surveys. The primary goal of the program is to develop a geologic framework in areas determined to be of important economic, social, or scientific interest to individual States. Oklahoma’s STATEMAP plan consists of two goals:
- Detailed mapping at 1:24,000 scale in and around concentrated urban areas and their expanding suburbs that will help define potential hazards, soil types, aggregate resources and groundwater aquifers.
- Regional mapping at 1:100,000 scale across the entire state. These areas are currently covered by good to poor mapping, all of which needs to be compiled, field checked, corrected, and digitized onto a single standardized topographic base. These smaller scale geologic maps will also be used in ongoing compilation of the new 1:500,000-scale geologic map of Oklahoma.
These individual geologic maps are published as Oklahoma Geologic Quadrangle Maps and are available for free download on this website. Downloads available for each quadrangle map include: a PDF of the published map with cross section that a user can print with a plotter, a zip file containing all the geologic map data features in an ESRI shapefile format that can be used in a GIS, and a metadata or text (.rtf) document that describes the data, including the intent, geographic context, mapping process, and any uncertainties that exist in the mapping and data.
COGEOMAP Goals and Products
The COGEOMAP program was a cooperative effort between the U.S. Geological Survey and State Geological Surveys. The primary objective of the program was to “promote new geologic mapping that meets high-priority Federal and State objectives” (Reinhardt and Miller, 1987, p. 1). In Oklahoma, the program included the Arkansas Geological Commission and funding extended from October 1984 to June 1993. The goal of the Oklahoma part of the COGEOMAP program was to produce a series of detailed, 1:24,000 geologic maps across the northern part of the Ouachita fold-and-thrust belt and the extreme southern part of the Arkoma Basin. The purpose of the maps was to aid new resource (coal, natural gas) exploration and development efforts in the area.
Fifteen individual geologic maps were produced as part of Oklahoma’s COGEOMAP program and the remaining seven were produced under STATEMAP. These individual geologic maps are published as Oklahoma Geologic Quadrangle Maps and are available for free download on this website. Downloads available for each quadrangle map include: a PDF of the published map with cross section that a user can print with a plotter, a WinZip file containing the geologic map data features in an ESRI shapefile and TIFF format that can be used in a GIS, and a metadata or text (.txt) document that describes the data, including the intent and geographic context.
