Bedding features in the core from the USGS Gulf Coast #4 Bonham borehole, in the Eagle Ford Group mudstones from a depth of about 401 feet, Fannin County, Texas. The Eagle Ford Group lies underneath the Austin Chalk and serves as the source rock for much of the Austin Chalk's petroleum.

Geologists discuss the geology of Jurassic rocks in thurst-faulted structures near the southern limit of Western North Slope.

Geologist examines f Faulted and folded petroleum source rocks in Jurassic and Cretaceous rocks (Kingak Shale, pebble shale unit, and gamma-ray zone of Hue Shale) in southern part of Western North Slope. Thermal maturity of these rocks is at the upper limit of oil preservations.

Geochemists use platinum, silica, and ceramic crucibles, shown here in a glass container called a desiccator.  Silica is used because it is resistant to extremely high temperatures and because it is chemically inert. Silicon, linked up with a pair of oxygen molecules as silicon dioxide, is known as silica.

Mineral elements provide the color in fireworks. Barium produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow. Other colors can be made by mixing elements: strontium and sodium produce brilliant orange; titanium, zirconium, and magnesium alloys make silvery white; copper and strontium make lavender.

The 43rd annual Mineral Commodity Summaries report from the USGS National Minerals Information Center is the earliest comprehensive source of 2019 world mineral production data.

One of the most productive areas in the world for oil remains rich in the resource, according to the latest USGS assessment. This assessment is for undiscovered, technically recoverable oil and gas resources in conventional accumulations.

The Alaska North Slope is rich in gas hydrate-bearing formations which contain significant natural gas resources. The USGS has released a geologically based assessment for how much of these resources is technically recoverable.

To make America’s economy and defense more secure, the Administration has released “A Federal Strategy to Ensure Secure and Reliable Supplies of Critical Minerals.” Among other roles, these mineral commodities are vital to renewable energy infrastructure like solar panels, wind turbines, and batteries.

USGS researchers drill a research well located on the south side of U.S. 90, 7.1 miles east of Brackettville, Texas. This core was drilled by USGS during field work for an oil and gas assessment for the Eagle Ford of the Gulf Coast Basins. Cores like these provide information on the various rock layers, such as their make-up, their age, etc.

The natural oil seep in this photo is located in Pescadero Creek County Park, where the Canyon Trail crosses Tarwater Creek. The oil is black, has a taffy-like consistency, and smells like motor oil.
