WebSlate is mostly likely formed by low grade metamorphism and develops excellent rock cleavage with the tendency to break into flat slabs . Schist experiences medium to high grade metamorphism and tends to have more muscovite , and biotite producing a medium to coarse grained rock with a scaly foliation . Gneiss typically formed in high grade … Schist is a medium-grained metamorphic rock showing pronounced schistosity. This means that the rock is composed of mineral grains easily seen with a low-power hand lens, oriented in such a way that the rock is easily split into thin flakes or plates. This texture reflects a high content of platy minerals, such as micas, talc, chlorite, or graphite. These are often interleaved with more granular … 顔えくぼ作り方
