9 Formation
9.1 Formation
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
