Family of silicate minerals containing iron, magnesium, and calcium in varying amounts Differ from amphibole family by lack of water in the crystals The most common variety, augite, contains aluminum as well Generally forms very dark green to black stubby prisms
any of a group of crystalline silicate mineral common in igneous and metamorphic rocks
A common mineral occurring in monoclinic crystals, with a prismatic angle of nearly 90°, and also in massive forms which are often laminated
any group of crystalline silicateminerals common in igneous and metamorphic rocks and containing two metallic oxides, as of magnesium, iron, or calcium - BACK>>
any of a group of crystalline minerals containing silicates of iron, magnesium and calcium
A group of important rock-forming silicate minerals of variable composition, among which calcium-, magnesium-, and iron-rich varieties predominate. Common pyroxenes belong to either the low-calcium enstatite-(ortho)ferrosilite series, (Mg,Fe)SiO3, or the high-calcium diopside-hedenbergite series, Ca(Mg,Fe)Si2O6. Rare pyroxenes include jadeite, aegirine, and johannsenite. See also enstatite
A group of single chained inosilicate minerals whose basic chemical unit is the silica tetrahedron (SiO4) They are common rock forming minerals and are found in most igneous and metamorphic rocks They form at high temperatures with very little water in the crystallization environment
It varies in color from white to dark green and black, and includes many varieties differing in color and composition, as diopside, malacolite, salite, coccolite, augite, etc
Hard, dense, glassy to resinous minerals found chiefly in dark igneous rocks and, less often, in dark gneisses and schists They usually occur as well-formed short, stout, columnar crystals that appear almost square in cross section
Pyroxene is an essential constituent of many rocks, especially basic igneous rocks, as basalt, gabbro, etc
