Notes on interpretation of geophysical data over areas of mineralization in Afghanistan
Afghanistan has the potential to contain substantial metallic mineral resources. Although valuable mineral deposits have been identified, much of the country’s potential remains unknown. Geophysical surveys, particularly those conducted from airborne pl |

Digitized data from ground geophysical surveys in Afghanistan
Surveys originally carried out by Soviet geophysicists from 1972 through 1974 were digitized. Georeferencing was problematic as were some of the measured characteristics; we explain what we did and how we have understood these data. |

Focus areas for data acquisition for potential domestic resources of 11 critical minerals in the conterminous United States, Hawaii, and Puerto Rico—Aluminum, cobalt, graphite, lithium, niobium, platinum-group elements, rare earth elements, tantalum, titanium, and tungsten
Geographic areas within the US where deposits of certain critical mineral resources might be found. With state agencies and other organizations, USGS intends to conduct studies that will help locate critical mineral resources within these areas. |
