Определение amphibolite facies в Английский Язык Английский Язык словарь
One of the major divisions of the mineral facies classification of metamorphic rocks, encompassing rocks that formed under conditions of moderate to high temperatures (950°F, or 500°C, maximum) and pressures. Less-intense temperatures and pressures form rocks of the epidote-amphibolite facies, and more-intense temperatures and pressures form rocks of the granulite facies. Amphibole, diopside, epidote, plagioclase, certain types of garnet, and wollastonite are minerals typically found in amphibolite facies rocks. They are widely distributed in Precambrian gneisses and probably formed in the deeper parts of folded mountain belts
One of the major divisions of the mineral facies classification of metamorphic rocks, encompassing rocks that formed under moderate temperature (500-750°F, or 250-400°C) and pressure conditions. This facies grades into the greenschist facies under less intense metamorphic conditions and into the amphibolite facies with greater temperature and pressure. Typical minerals include biotite, almandine garnet, plagioclase, epidote, and amphibole. Chlorite, muscovite, staurolite, and chloritoid may also occur
