Wilcox Group Apparent Thickness, Gulf Coast (wlcxthkg) 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...

Included here are U-Pb detrital zircon and Ar/Ar feldspar geochronologic data for middle Cenozoic sedimentary and volcanic rocks collected by Jens-Erik Lundstern and Theresa M. Schwartz in several parts of southern Nevada, U.S. The target strata are the lowest Cenozoic sedimentary rocks deposited above the base-Cenozoic unconformity. U-Pb detrital zircon data were obtained at the University of Arizona LaserChron Center in Tucson, Arizona in February 2021, October 2021, and January 2023. 40Ar/39Ar geochronologic data were collected at the U.S. Geological Survey in Denver, Colorado.

This study is one of several regional groundwater availability studies being done as part of the USGS Water Availability and Use Science Program. Groundwater from the coastal lowlands aquifer system is used mainly for public, irrigation, and industrial supply. Land-surface subsidence related to groundwater pumping is an issue of ongoing concern within this study area. During the first two years of...

This geodatabase, digitized from published resources, includes the position of volcanic ash-bed localities, structural data of inclined beds, orientation of geologic contacts and structural contours of specified stratigraphic horizons, and geographic extent of mapped geologic outcrops. This geologic compilation includes a geodatabase with applicable spatial feature classes accompanied by non-spatial tables with information that describes the data sources, glossary...

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...
