The U.S. Geological Survey (USGS) estimates at least 1 million metric tonnes of rare earth element resources within the Khanneshin carbonatite in Helmand Province, Afghanistan. This estimate comes from a 2009-2011 USGS study funded by the Department of Defense’s Task Force for Business and Stability Operations (TFBSO).

The Khanneshin carbonatite contains a major potential source of light rare earth elements (LREE), such as lanthanum, cerium, and neodymium. The LREE prospects in the Khanneshin carbonatite are comparable in grade to world-class deposits like Mountain Pass, CA, and Bayan Obo in China, both of which primarily contain LREE. (more…)

Searching for the “Perfect Glass”

Washington, D.C.— Glasses differ from crystals. Crystals are organized in repeating patterns that extend in every direction. Glasses lack this strict organization, but do sometimes demonstrate order among neighboring atoms. New research from Carnegie’s Geophysical Laboratory reveals the possibility of creating a metallic glass that is organized on a larger scale. Their results are published June 17 in Science.

Scientists have discovered glasses that demonstrate order among the nearest neighboring atoms, called short-range order, and a slightly wider range of atoms, called medium-range order. Most research about finding or creating a glass with a long-range, nearly crystalline, level of order—referred to as the perfect glass state—has been conducted on ice and the minerals silica and zeolite. But no research into long-range order glass has been successful until now. (more…)

Rare Earth Elements: The World is Rapidly Running Out and China Has Most of The Remaining Supply

Most people have no idea what rare earth elements are, but a wide array of the technologies that we use every single day are dependent on them.

Without rare earth elements, we would have no hybrid car batteries, flat screen televisions, cell phones or iPods. Without rare earth elements, the entire “green economy” would not be able to function, because almost all emerging green technologies use them.
