Amphibolite forms when basaltic rock is subjected to higher temperatures between 550 C and 750 C) and slightly greater pressure range than that which yields greenschist. 7.5 ). Garnet (almandine), pyroxene, biotite, titanite, magnetite, epidote, chlorite, and quartz are also frequent constituents. It can be produced through the metamorphism of mafic igneous rocks such as basalt and gabbro, or from the metamorphism of clay-rich sedimentary rocks such as marl or graywacke. It is made of amphiboles (usually hornblende) and plagioclase. Biopyriboles have chain widths and repeat sequences like pyroxenes (single-chain repeats), amphiboles (double-chain repeats), and triple-chain repeats. Amphibolite is a rock of convergent plate boundaries where heat and pressure cause regional metamorphism. What parent rock (protolith) does Slate form from? amphibolite, a rock composed largely or dominantly of minerals of the amphibole group.

References. There is no such mineral as "chrysotile asbestos"; there is a mineral "chrysotile" that crystallizes into a fibrous material referred to as asbestos but not all varieties of serpentinite contain it. The mineral hornblende has very few uses. 7.5.2.8 Amphibolites. Uses of amphibolite Amphibolite is harder than limestone and heavier than granite so for this reason amphibolite is quarried and crushed for use as an aggregate in highway construction and as a ballast stone in railroad construction. General considerations Amphiboles are found principally in metamorphic and igneous rocks. It is composed mainly of flake-shaped mica minerals in parallel alignment.

The researchers state that the amphibolite is believed to have been altered 2.6 billion years ago by tectonic pressures of 14 kilobars and temperatures of 190°C. The amphiboles are usually members of the hornblende group. For metamorphic rocks, pressures range from a relatively low-pressure of 3,000 bars around 5-6 kilometers below the Earth's surface to a relatively high pressure of 50,000 bars around 15-35 kilometers. Crushed and used as road construction and railway ballast. Most samples have a relatively simple composition: hornblende + plagioclase. The combination of its ability to be polished, its dark color and its texture have made amphibolite a popular dimension stone in construction.
