Webshale is metamorphosed to produce slate, phyllite, schist, and gneiss. quartz sandstone and limestone are metamorphosed into quartzite and marble index minerals minerals used to estimate the temperature, depth, and pressure at which a rock undergoes metamorphism migmatites A rock exhibiting both igneous and metamorphic rock characteristics.
Slate is a fine-grained metamorphic rock that shows no obvious compositional layering, but can easily be split into thin slabs and plates. It is usually formed by low-grade regional metamorphism of mudrock. This mild degree of metamorphism produces a rock in which the individual mineral crystals remain microscopic in size, producing a characteristic slaty cleavage in which fresh cle… WebThe presence of the foliated rock, likely slate, suggests that, before this rock metamorphosed, it was composed of limestone (the parent rock of marble) layered with small-grained sedimentary rocks, like siltstone or shale. Siltstone and shale develop foliation during metamorphism, while limestone does not.
