The word igneous means that the rock became a solid after having originally been hot magma, or lava. Low-grade metamorphic rocks are often fine grained. Phyllite- thisis fine foliated metamorphic rock that is found in areas of low-grade metamorphism, it is made of mainly of very fine-grained mica. The identification of a metamorphic rock depends largely on recognition of foliation and other textures. Other examples include gneiss, slate, schist, and quartzite to name a few. As metamorphic grade increases, what do we generally observe in terms of the degree of foliation in rocks? Anthracite is a type of coal with a high carbon count, few impurities and with a high luster (meaning it looks shiny). Here is a picture of quartzite.
