Quartzite is a hard metamorphic rock consisting essentially of interlocking quartz crystals. It is a non-foliated metamorphic rock formed during the metamorphism of sandstone. 9. Slate. Slate is a low-grade and fine-grained metamorphic rock that can be separated into thin pieces. It is a type of foliated metamorphic rock that is produced by the metamorphism of shale. Slates are predominantly
21/06/2018· Metamorphic rocks have scientific significance for parsing the evolutionary process of an orogenic belt. The Wuliangshan area is a very complex region of metamorphism, where it is nearly impossible to conduct conventional geological investigation because of the extremely rugged topography and difficult travel conditions. Previous research on the area's metamorphic rocks is limited.

11/08/2020· Quartzite is a common, crystalline-textured, intermediate- to high-grade metamorphic rock. It forms by metamorphism of quartzose sandstones or siltstones. Quartzite can be entirely composed of interlocking quartz crystals, or the original sand grains may still be visible. This rock is hard (H = 7), will not bubble in acid (unlike marble), and can be almost any color.
