As of November 2024, the IMA - CNMNC List of Minerals lists 6,100 valid minerals, including 1,153 pre-IMA minerals (grandfathered), and 97 questionable minerals. [2] Also as of November 2024 [update] , the Mineralogical Society of America's Handbook of Mineralogy lists 5,663 species, [ 3 ] and the IMA Database of Mineral Properties/RRUFF ...

Most rocks contain silicate minerals, compounds that include silica tetrahedra in their crystal lattice, and account for about one-third of all known mineral species and about 95% of the earth's crust. [6] The proportion of silica in rocks and minerals is a major factor in determining their names and properties. [7]
Introduction to the Rock-forming Minerals is a condensed version of the multi-volume work Rock-forming Minerals by the same authors, which was published in 1962-3 with a second edition beginning in 1978, totalling 11 volumes. The condensed version omits some references, etymology, and chemical analysis present in the larger work.
Lithium aluminium silicate mineral spodumene. Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust. [1] [2] [3] In mineralogy, silica (silicon dioxide, SiO 2) is usually considered a silicate mineral rather than an ...
Minerals in soils are found in two types; primary and secondary. [5] "A primary mineral has not been altered chemically since its crystallization from a cooling magma." [5] Additionally, a primary mineral is defined as a mineral that is found in soil but not formed in soil, whereas secondary minerals are formed during weathering of
In rocks, some mineral species and groups are much more abundant than others; these are termed the rock-forming minerals. The major examples of these are quartz, the feldspars, the micas, the amphiboles, the pyroxenes, the olivines, and calcite; except for the last one, all of these minerals are silicates. [39]
