tatanan
pyroxenites watu beku ultramafic kang arupi mineral saka klompok pyroxene, kayata augite lan diopside, hypersthene, bronzite utawa enstatite.
amarga kanggo ngganti ing kondisi lingkungan, rocks sing digawe panas lan pressurized jero nang permukaan bumi. pseudotachylite kawangun saka panas nemen disebabake magma utawa dening tabrakan kuat lan gesekan lempeng tektonik.
