WebSchist: Schist is a metamorphic rock that is characterized by its foliated texture, which is a result of the alignment of mineral grains during metamorphism. Schist commonly contains minerals such as mica (such as muscovite or biotite ), quartz , and sometimes garnet , staurolite, or chlorite , depending on the specific type of schist . WebFigure 3.6.8.

WebWhat does it mean when a metamorphic rock has foliation Mineral grains are aligned in layers by pressure A parent rock goes through metamorphism. The resulting metamorphic rock is nonfoliated, contains intergrown mineral crystals, and reacts with hydrochloric acid. What was the parent rock and what is the resulting metamorphic rock? WebPut the following minerals in order according to Moh's hardness scale with 10 being the hardest and 1 being the softest. 1=talc; 2=gypsum; 3=calcite; 4=fluorite; 5=apatite; 6=orthoclase feldspar; 7=quartz; 8=topaz; 9=corundum 10=diamond.

WebQuartz: Quartz is a common mineral in many metamorphic and felsic igneous rocks that, like the potassium feldspars, also has a non-metallic luster and hardness greater than glass. Unlike the potassium feldspars, however, quartz does not exhibit cleavage, which easily distinguishes it from feldspar minerals.
