Phlogopite can coexist with amphibole at low pressures and is stable to higher pressure than amphibole. The abundance of phlogopite obviously depends on the amount of potassium present, and most experimental studies use K-rich (relative to …

Amphibolite is a dark, heavy, metamorphic rock composed mostly of the mineral amphibole. Amphibolites have very little to no quartz. “Amphibole” refers not to a single mineral, but to a group of minerals.

Amphibole is a group of inosilicate minerals. They form prism or needlelike crystals. [1] Many of them are asbestos. They are double chain SiO 4 tetrahedra, linked at the vertices. Usually they contain ions of iron and/or magnesium in their structures. Amphiboles can be green, black, colorless, white, yellow, blue, or brown.
