What is amphibolite schist?
Amphibolite (/æmˈfɪbəlaɪt/) is a metamorphic rock that contains amphibole, especially hornblende and actinolite, as well as plagioclase feldspar, but with little or no quartz. It is typically dark-colored and dense, with a weakly foliated or schistose (flaky) structure.
Is epidote an amphibole?
epidote-amphibolite facies, one of the major divisions of the mineral-facies classification of metamorphic rocks, the rocks of which form under moderate temperature and pressure conditions (250°–400° C [500°–750° F] and up to 4 kilobars [1 kilobar equals about 15,000 pounds per square inch]).
What is amphibolite used for?
It is used as paving stones and as a veneer or facing on buildings (both for interior and exterior use). It is also used as crushed stone for the usual crushed stone applications such as road and railroad bed construction. In this application it is used locally, near the source of the amphibolite.
What type of rock is amphibolite schist?
metamorphic rocks
2.8 Amphibolites. Amphibolites are the most common metamorphic rocks formed by regional metamorphism under high pressure and high temperature (Fig. 7.5). The amphibolites usually occur along with the mica schist and gneiss.
Where is amphibolite rock found?
Amphibolite (or hornblende) can also be found as inclusions in moss agate, dendritic agate and zoisite. Amphibolite is commonly found in areas where mountains have formed. Deposits have been found on every continent except Antarctica.
What is the original rock of amphibolite?
Mafic igneous rocks (e.g., basalts and gabbros) and sedimentary dolomite can be the parent rocks of amphibolite.
What is the difference between amphibole and amphibolite?
is that amphibolite is (geology) any of a class of metamorphic rock composed mainly of amphibole with some quartz etc while amphibole is (geology) a large group of structurally similar hydrated double silicate minerals, containing various combinations of sodium, calcium, magnesium, iron, and aluminium/aluminum.
Where can amphibolite be found?
Amphibolite is found around metamorphic and igneous rock intrusions that solidify between other rocks that are located within the Earth. Also, amphibolite has significant components found in both volcanic and plutonic rocks that range in composition from granitic to gabbroic.
