The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K),
Borehole induction conductivity (IC) and gamma logging are geophysical techniques that provide bulk electrical conductivity and natural gamma trends of geological formations. The measured unit of IC i
This spatial database "usgs_Global_REE.gdb" was created for use in a geographic information system (GIS) to support research on global rare earth deposits and occurrences by the U.S. Geological Survey
This dataset tabulates sorted simulation results for amounts of copper in metric tons. The data are output from the EMINERS computer program (Duval, J.S., 2012, Version 3.0 of EMINERS—Economic Miner
Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies
