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 granula… WebGneiss can form in several different ways. The most common path begins with shale, which is a sedimentary rock.Regional metamorphism can transform shale into slate, then phyllite, then schist, and finally into …

This granulite facies schist has coarse sillimanite prisms that can be seen in length sections, and in their diamond-shaped cross sections. The lower second order blue birefringence can be seen in the long sections. Plane- and cross-polarized light views. Field width is 3 mm.
