Data sets include drill-hole from core and geophysical logs, surface geology and elevation, and helicopter electromagnetic survey data. The model may be explored and .jpg or .tiff images or using specialized software provided.
Aeromagnetic surveys of Texas, merged to form seamless grids across the state. Gravity anomaly data are provided as well.
Data provided in a variety of formats.
Probabilistic estimates of the amounts of undiscovered gold, silver, copper, lead, and zinc in conventional types of mineral deposits in the United States.
Digital and analog archives comprising more than 1,000 surveys, covering approximately 8,000,000 line-km of data, flown at various flight heights and line spacings
Principal basement structures formed during the Precambrian in the continental United States based on interpretation of regional aeromagnetic anomaly data of North America.
Characteristics of bedrock and surficial geologic terranes and structural features at various levels of detail. The information provided here are intended for use in the synoptic study of large areas, and are likely not suitable for detailed study of geog
A GIS database of geologic units and structural features in Texas, with lithology, age, data structure, and format written and arranged just like the other states.
This report presents the results of analyses and interpretation of aerial gamma-ray, Landsat TM, geologic, and digital elevation data of the Big Bend area in Texas.
The USGS had an aerial survey flown over parts of Cameron, Hidalgo, and Willacy Counties in Texas. The aerial survey included measurements of the earth's magnetic field and of the radioactivity of the surface rocks and soils.
Digital geologic map information with a consistent set of attributes, part of a national compilation of similar maps.
Available in formats compatible with GIS.
