Serpentinite is a soft, compact, pale green to greenish-black rock consisting wholly or largely of serpentine minerals—antigorite, chrysotile, or lizardite (allomorphs of Mg 3 Si 2 O 5 (OH) 4 ). These minerals are usually produced by the hydrous alteration of olivine, orthopyroxene, and, to a lesser extent, clinopyroxene. The list below divides metamorphic rocks into foliated and nonfoliated varieties. Foliated rocks have platy or elongate minerals aligned in roughly parallel planes or in wavy bands or planes. Nonfoliated rocks may show colored bands that reflect minute impurities in the rock, but the dominant minerals show no visible alignment.Quartzite is a non-foliated, granoblastic (intergrown, interlocking, equidimensional, enlarged grains), metamorphic rock composed predominantly of quartz.

Many serpentinites have a foliated look to them, but it's really not due to an alignment of crystals.There was once a breccia that formed in a fault zone and was later metamorphosed under confining pressure, resulting in this nonfoliated metabreccia. It indicates faulting (brittle behavior at shallow depths in the crust) followed by either burial metamorphism in a sedimentary basin or contact metamorphism by an intruding magma body.

In this texture, the mineral crystals in the rock are aligned with each other. This alignment may be displayed as parallel planes along which the rock splits, by overlapping sheets of platy minerals such as micas, by the parallel alignment of elongate minerals such as amphiboles, or by alternating layers of light and dark minerals.Serpentinite from the Maurienne valley, Savoie, French Alps Sample of serpentinite from the Golden Gate National Recreation Area, California, United States Chromitic serpentinite (7.9 cm (3.1 in) across), Styria Province, Austria.

All of ...Foliated metamorphic rock that forms under high pressure and low temperature. the destruction of pre-existing minerals in a rock due to metamorphism and the growth of new ones. Rock transformation that occurs at high temperatures associated with the intrusion of magma into cooler country rock. Fine-grained, foliated.It may be schistose or massive. Soapstone is formed by metamorphism of ultramafic protoliths (eg dunite or serpentinite) and metasomatism of siliceous dolomites. By mass, “pure” steatite is roughly 63.37% silica, 31.88% magnesia, and 4.74% water. It commonly contains minor quantities of other oxides such as CaO or Al2O3.
