Scanning Electron Microscope Image of Finchite

A scanning electron microscope image of the newly discovered mineral finchite. The Denver Microbeam Lab provided this scan of finchite in order to help describe and identify the mineral as a new one. Finchite is a uranium mineral first observed in Martin County, Texas.

USGS Scientists Sarah Davis, Taylor Mills, and David Naftz collect soil samples near the Pinenut uranium mine. Mine features visible in the background include the gray ore stockpile at the far left, the head frame used to access the underground mine workings at mid left, and the detention pond containing all water produced on the mine site on the right.
