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...

The fundamental geologic unit used in the 1995 National Oil and Gas Assessment was the play, which is defined as a set of known or postulated oil and or gas accumulations sharing similar geologic, geographic, and temporal properties, such as source rock, migration pathways, timing, trapping mechanism, and hydrocarbon type. The geographic limit of each play was defined and mapped by the geologist responsible for each province. The play boundaries were defined geologically as the limits of the geologic elements that define the play, such as the limits of the reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are plays that border the Federal-State water boundary. In...

The Apparent Wilcox Group thickness maps are contoured from location and top information derived from the Petroleum Information (PI) Wells database. The Wilcox apparent thickness map was constructed by searching for Wilcox and Midway Group tops. Apparent thickness is computed by subtracting Midway top from the Wilcox top. Geographic control is superimposed on the maps from USGS state line, county, elevation and other data files. The veracity of the PI Wells database is being checked by comparison to published cross sections and geologic maps. Interpretation of the depth to Wilcox and apparent thickness maps along with published measured sections and cross sections indicates that portions of Texas, Louisiana, Mississippi...

The surficial geologic map of the Eastern and Central United Statesdepicts the areal distribution of surficial geologic deposits and othermaterials that accumulated or formed during the past 2+ million years,the period that includes all activities of the human species. Thesematerials are at the surface of the earth. They make up the "ground"on which we walk, the "dirt" in which we dig foundations, and the �soil�in which we grow crops. Most of our human activity is related in oneway or another to these surface materials that are referred tocollectively by many geologists as regolith, the mantle of fragmentaland generally unconsolidated material that overlies the bedrockfoundation of the continent. The map is based...

The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, hydrocarbon plays or assessment units are defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The province boundaries were drawn on the county lines that most closely followed the natural geologic boundaries.

This map shows the structural configuration of the top of the Travis Peak or Hosston Formations in feet below sea level. The map was produced by calculating the difference between a datum at the land surface (either the Kelly bushing elevation or the ground surface elevation) and the reported depth of the Travis Peak or Hosston. This resulted in 18,941 wells for which locations were available. After deleting the wells with obvious data problems, a total of 18,933 wells were used for the map. The data are provided as both lines and polygons, and the proprietary wells that penetrate the top of the Travis Peak or Hosston Formations are graphically displayed as quarter-mile cells. The well information was initially...

Cell maps for each oil and gas assessment unit were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry, or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the...

This CD-ROM contains a digital version of the Geologic Map of theUnited States, originally published at a scale of 1:2,500,000 (Kingand Beikman, 1974b). It excludes Alaska and Hawaii. In addition tothe graphical formats, the map key is included in ASCII text.A geographic information system (GIS) allows combining andoverlaying of layers for analysis of spatial relations not readilyapparent in the standard paper publication. This disc contains onlygeology. However, digital data on geology, geophysics, andgeochemistry can be combined to create useful derivative products--for example, see Phillips and others (1993).This CD-ROM contains a copy of the text and figures fromProfessional Paper 901 by King and Beikman (1974a)....

Debris flows, debris avalanches, mud flows and lahars arefast-moving landslides that occur in a wide variety of environmentsthroughout the world. They are particularly dangerous to life andproperty because they move quickly, destroy objects in their paths,and can strike with little warning. The purpose of this map is toshow where debris flows have occurred in the conterminous UnitedStates and where these slope movements might be expected in thefuture.

The Positive Structural Elements coverage maps, in the form of polygons, are known structural highs within the province that commonly define a basin proper or influence the occurrence of discovered or undiscovered hydrocarbon accumulations. Positive Structural Elements are shown here as geographic polygons that were only generally defined and mapped by the geologist responsible for the province. These Positive Structural Elements were mapped mostly from other resources, including previously published maps and literature (see Pollastro and Viger, 1998, in text portion of publication DDS-69-A). The Positive Structural Elements boundaries were defined in the period from March to May, 2000.

This isopach map shows the thickness of the interval from the top of the Travis Peak or Hosston Formations to the top of the Cotton Valley Group. The map was produced by first subtracting the values of the top of the Travis Peak or Hosston from those of the top of the Cotton Valley Group. This resulted in a data set of 8,585 values for which locations were available. After deleting the wells with obvious data problems, a total of 8414 wells were used to generate the map. The data are provided as both lines and polygons, and the proprietary wells that penetrate this interval are graphically displayed as quarter-mile cells. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well...

The depth to top of the Wilcox Group is contoured from location and top information derived from the Petroleum Information (PI) Wells database. The depth to Wilcox map represents the tops found in the database with the addition of surface geology from USGS maps and field data. The veracity of the PI Wells database is being checked by comparison to published cross sections and geologic maps. Interpretation of the depth to Wilcox and apparent thickness maps along with published measured sections and cross sections indicates that portions of Texas, Louisiana, Mississippi and Alabama contain broad areas where a 20 to 40 foot net thickness of lignite and coal occur at shallow depths. The thicker coal zones are attributed...
