Geology, Energy, and Minerals Mission Area

We lead the Nation’s geologic mapping and provide impartial scientific information on geologic resources and their supply chains. Our work includes leading the development of the List of Critical Minerals, assessing domestic and foreign energy and mineral resources, and mapping areas with resource potential.
 

Our science informs key investments and crucial resource management decisions to support a strong, secure and sustained Nation.

Assessment of undiscovered conventional oil and gas resources in the Niger Delta Province of Nigeria and Cameroon, 2026 Assessment of undiscovered conventional oil and gas resources in the Niger Delta Province of Nigeria and Cameroon, 2026

Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean conventional resources of 11.4 billion barrels of oil and 88.2 trillion cubic feet of gas in the Niger Delta Province of Nigeria and Cameroon.

Trace element heterogeneity and crystallization history of the Plesovice zircon: Implications for its use as a U–Pb LA-ICP-MS reference material Trace element heterogeneity and crystallization history of the Plesovice zircon: Implications for its use as a U–Pb LA-ICP-MS reference material

Zircon crystals from Plešovice hyperpotassic granulite (HPG) have been widely used as a reference material for LA-ICP-MS dating. Detailed cathodoluminescence (CL) imaging and trace element analysis reveal a complex internal structure of Plešovice zircon linked to extreme chemical heterogeneity, which allows us to distinguish different zircon domains formed during its crystallization: (i)...

Effect of mineral deposit data on predictions from the three-part approach to quantitative mineral resource assessment—A study of 16 previous U.S. Geological Survey assessments Effect of mineral deposit data on predictions from the three-part approach to quantitative mineral resource assessment—A study of 16 previous U.S. Geological Survey assessments

The three-part approach to quantitative mineral resource assessment requires information about the properties of undiscovered mineral deposits in an assessment area. These properties are unknown, so the properties of discovered mineral deposits of the same mineral deposit type are used instead. In the three-part approach, these discovered mineral deposits come from around the world, and...
