U.S. Geological Survey Fact Sheet 2006-3044 Freshwater Diatomite Deposits in the Western United States By Alan R. Wallace; David G. Frank; and Alan Founie 2006

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 erected in about 3700 B.C. Now an average new American home contains more than 7 metric tons of gypsum in the form of more than 6,000 square feet of wallboard....

Each chapter of the 2020 edition of the U.S. Geological Survey (USGS) Mineral Commodity Summaries (MCS) includes information on events, trends, and issues for each mineral commodity as well as discussions and tabular presentations on domestic industry structure, Government programs, tariffs, 5-year salient statistics, and world production and...

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 chemically inert. Rocks containing diatomite are excellent reservoir rocks for hydrocarbons....

State mineral data - After all information from the USGS annual canvass of domestic mineral industries is compiled and the mineral commodity chapters (Volume I of the Minerals Yearbook) are released, a Statistical Summary chapter is completed, with table 5 (and several other tables) presenting the earliest State-by-State data, including total State production and production

The Pacific Region has nine USGS Science Centers in California, Nevada, and Hawaii. The Regional Office, headquartered in Sacramento, provides Center oversight and support, facilitates internal and external collaborations, and works to further USGS strategic science directions.

Human disturbance of coastal ecosystems is intense and can mask ecological responses to global climate change. This is the major conclusion of a large effort by U.S. Geological Survey (USGS) scientist James E. Cloern and University of California-Davis scientist Alan D. Jassby, who analyzed phytoplankton data from 154 of the world’s coastal water bodies.

Allen's interests are in the broad area of fluvial geomorphology, with emphasis on understanding the erosion, transport, storage, delivery, and age of fluvial sediment. Much of Allen’s research is focused on developing approaches to understand the significant sources of fine-grained sediment using geochemical tracers or fingerprints at both small and regional watershed scales.

Freshwater diatomite deposits in the Western United States are found in lake beds that formed millions of years ago. These diatom-rich sediments are among the Nation's largest commercial diatomite deposits. Each deposit contains billions of tiny diatom skeletons, which are widely used for filtration, absorption, and abrasives. New studies by the U.S. Geological Survey (USGS) are revealing how ...

in 2006, the mineral industries of Central america produced a variety of metals, industrial minerals, and mineral fuels. in the metals mining sector, antimony, gold, iron ore, lead, silver, and zinc were produced. Production of nonprecious refined metals consisted almost exclusively of steel production in

minerals and to aid in the resource evalu-ation of these deposits, U.S. Geological Survey (USGS) scientists are studying the reasons why many ancient lakes pro-duced such large diatomite deposits and why others did not. How Did Diatomite Deposits Form? Freshwater diatomites in the Western States formed over thousands to millions of years.

The work on this volume began in January 1972, but in a broader sense its production began many years ago. The chapters were written by geologists most of whom have had many years of experience studying the geology of mineral deposits, and more particularly the commodities about which they have written here. A total of nearly 2,300 man-years of professional experience in the geology of mineral ...
