Email mineralsusgs.gov httpsminerals.usgs.gov. Throughout most of human history environmental stewardship during mining has not been a priority partly because of the lack of applicable laws and regulations and partly because of ignorance about the effects that mining can have on the environment. In the United States the National
Fluorine compounds are essential in numerous chemical and manufacturing processes. Fluorspar is the commercial name for fluorite isometric CaF2 which is the only fluorine mineral that is mined on a large scale. Fluorspar is used directly as a fluxing material and as an additive in different manufacturing processes. It is the source of fluorine in the production of hydrogen fluoride or
The USGS Spectral Library is a reference data base containing reflectance spectra and associated sample documentation that can be used to identify minerals determine mineral chemistry discriminate between vegetation species and detect hydrocarbons and contaminants in the environment. The library is an important resource for analying imaging spectrometer data also known as hyperspectral
Ground water leaches ore minerals and redeposits them in ones near the water table. This leaching process concentrates these minerals as ore that can be mined. Of the 15 major types of mineral deposits in the Western Hemisphere formed by action of ground water 13 occur in deserts.
Rocks and minerals are important for learning about earth materials structure and systems. Studying these natural objects incorporates an understanding of earth science chemistry physics and math. The learner can walk away with an understanding of crystal geometry the ability to visualie 3

Magnesium Mg is the eighth most abundant element and constitutes about 2 of the Earths crust and it is the third most plentiful element dissolved in seawater. Although magnesium is found in over 60 minerals only dolomite magnesite brucite carnallite and olivine are of commercial importance. Magnesium and other magnesium compounds are also produced from seawater
