The Mineral Resources Program provides data about California's varied non-fuel mineral resources (such as metals and industrial minerals), naturally occurring mineral hazards (such as asbestos, radon, and mercury), and information about active and historic mining activities throughout the state.

"mineral" commodities typically refer to solids that must be mined. The energy minerals coal and uranium are mined, and so can fall in either the energy or mineral category. For present purposes the term mineral resources includes all solids that must be mined, including coal and uranium.

Mineral commodities are vital for economic growth, improving the quality of life, providing for national defense, and the overall functioning of modern society. Minerals are being used in larger quantities than ever before and in an increasingly diverse range of applications. With the increasing demand for a considerably more diverse suite of mineral commodities has come renewed recognition ...

Garnet is a gemstone composed of metals (calcium, magnesium, iron, aluminum, and/or chromium) bonded to silica. It has a relatively high hardness, harder than silica sand, so small grains are used as an abrasive for both sand blasting and in sand paper. In contrast, talc, used in baby powder, is a very soft mineral.

Mineral Resource Principles. A geologist defines a mineral as a naturally occurring inorganic solid with a defined chemical composition and crystal structure (regular arrangement of atoms). Minerals are the ingredients of rock, which is a solid coherent (i.e., will not fall apart) piece of planet Earth.There are three classes of rock, igneous, sedimentary, and metamorphic.

China's mineral resources take the following characteristics: China's energy mineral resources are relatively abundant, but the structure of these types of resources is not ideal. The proportion of coal resources is relatively large while that of petroleum and natural gas resources is small in comparison.
