USGS Scientists Seeking Finchite by the Sulfur Springs Draw in Texas

Between Lamesa and Big Spring, Texas, runs the Sulfur Spring Draw, a dry creek. It's the site of an economic calcrete-type uranium deposit, the Sulfur Springs Draw Deposit, where a new mineral was discovered in 2015. The mineral, first observed by USGS scientist Bradley Van Gosen, is a uranium-mineral named finchite after long-time USGS uranium geologist Warren Finch. Read

Shearing of the Melozitna Granite

Geologist and cataclastic shear zones in the Melozitna granite in the Ruby batholith. This granite contains abundant monazite and high levels of thorium and rare earth elements. The shear zones accelerate erosion of the granite into streams, where the monazite that contains the rare earth elements can be concentrated. This area is part of the Bureau of Land Management's

Collecting a Gas Hydrate Research Core from the Indian Ocean

Scientists aboard the D/S Chikyu prepare to collect a research core drilled from marine sediments in the Indian Ocean. This research is part of the 2015 Indian National Gas Hydrate Program Expedition 02 (NGHP-02), which is a follow-up to the 2006 NGHP-01. 

NGHP-02 identified several large deposits of potentially producible gas hydrates in the Indian

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. Read more about our uranium research here
