Amphibolitovy
Amphibolitovy is a term that primarily refers to rocks of the amphibolite facies, a set of metamorphic conditions characterized by the presence of amphibole minerals. These rocks typically form under intermediate to high pressures and temperatures, generally ranging from 500 to 800 degrees Celsius and pressures from 5 to 10 kilobars. Amphibolitovy rocks are common in the roots of mountain belts and in ancient shield areas, indicating past tectonic activity and deep burial.
The mineral assemblage in amphibolitovy rocks is dominated by amphiboles, such as hornblende, and plagioclase feldspar.
The texture of amphibolitovy rocks is typically granoblastic or lepidoblastic, reflecting the recrystallization of minerals under
