7.2 Classification of Metamorphic Rocks – Physical Geology
WebJul 7, 2024 · To become schist, a shale must be metamorphosed in steps through slate and then through phyllite. If the schist is metamorphosed further, it might become a granular rock known as gneiss. …. This texture allows the rock to be broken into thin slabs along the alignment direction of the platy mineral grains. WebSlates are fine grained rock formed due to metamorphism of shale and they are characterized by continuous cleavage. With increasing grade I.e temper …. Part 1: Metamorphism 1. Organize phyllite, slate, schist, and gneiss based on increasing grade of metamorphism and explain your reasoning. 2. Gneiss is a foliated metamorphic rock identified by its bands and lenses of varying composition, while other bands contain granular minerals with an interlocking texture. Other bands contain platy or elongate minerals with evidence of preferred orientation. It is this banded appearance and texture - … See more Gneiss usually forms by regional metamorphism at convergent plate boundaries. It is a high-grade metamorphic rock in which mineral grains recrystallized under intense heat and pressure. This … See more Some specimens of gneiss contain distinctive minerals characteristic of the metamorphic environment. These minerals might include biotite, cordierite, sillimanite, kyanite, staurolite, andalusite, and garnet. Gneiss is sometimes … See more Gneiss usually does not split along planes of weakness like most other metamorphic rocks. This allows contractors to use gneiss as a crushed … See more Some gneiss accepts a bright polish and is attractive enough for use as an architectural stone.
