Alan Founie, the gypsum commodity specialist for the U.S. Geological Survey, has compiled the following information on gypsum, an abundant mineral that is one of the oldest building materials in the world. The earliest known use of gypsum as a building material was in Anatolia (in what is now Turkey) around 6000 B.C. It has been found on the interiors of the great pyramids in Egypt, which were

Cell phones, electric cars and lasers require a few essential, but rare, elements that have been produced and marketed mostly by China. Now, new USGS research on timeworn samples from the U.S. western mining era show potential new sources of the fundamental ingredients used in 21 st century technologies.. USGS scientists are reanalyzing rocks, minerals and associated mine tailing samples

Alan Founie, the diatomite commodity specialist for the U.S. Geological Survey, has compiled the following information on diatomite, used in everything from containing industrial spills to producing beer and wine. Diatomite is a soft, very fine-grained, siliceous sedimentary rock that is usually very light grey or beige in color. It is very finely porous, very low in density and essentially
