Shale 7) Which of the rocks listed below is the parent rock of quartzite? It is defined by having more than 50% platy and elongated minerals (such as micas or talc), often finely interleaved with quartz and feldspar. Schist is a strongly foliated medium-grade metamorphic rock. Photos of staurolite schist and kyanite schist are included later in this chapter. Schist (Garnet-Muscovite) Metamorphic. Schist Schist is medium grade metamorphic rock, formed by the metamorphosis of mudstone / shale, or some types of igneous rock, to a higher degree than slate, i.e. It is characterized by an abundance of platy or elongated minerals (micas, chlorite, talc, graphite, amphiboles) in a preferred orientation.Varieties of this rock type share similarities in appearance (schistosity) but may be highly variable in composition. The minerals that develop in a metamorphic rock depend upon: 1) the grade of metamorphism 2) the composition of the parent material Marble, Quartzite. granite. Distinctively metamorphic minerals such as garnet, staurolite, kyanite, and sillimanite occur in schists, depending on the metamorphic grade and starting composition of the parent rock. So the schist in Figure 8.23 is a garnet schist, and the one in Figure 8.28 is a muscovite schist, or simply a mica schist. Schist (pronounced / ʃ ɪ s t / SHIST) is a medium-grade metamorphic rock formed from mudstone or shale. The composition of the parent rock determines the metamorphic minerals and rocks that may form. Non-Foliated. This is a schist consisting almost entirely of staurolite and muscovite. Notice how the different layers are weathering at … Schist may contain accessory minerals such as garnet, tourmaline, and pyrite. Some common examples include the following: biotite schist, garnet-staurolite schist, sillimanite schist, granitic gneiss, mafic gneiss, etc. The parent rock of Hornblende Schist is. Characteristics include: Visible crystals Schist has medium to large, flat, sheet-like grains in a preferred orientation (nearby grains are roughly parallel). A Mica Garnet schist is a metamorphic rock formed from a shale or a granitic mother rock when this is squashed and heated at death in the crust. Parent Rock - Shale. Quartzite, Marble, Gneiss. Shale, siltstone, and some sandstones can provide the parent rock for schist. Texture - Foliated (Coarse-grained) Minerals present - Garnet and Muscovite.

Blueschist (/ ˈ b l uː ʃ ɪ s t /), also called glaucophane schist, is a metavolcanic rock that forms by the metamorphism of basalt and rocks with similar composition at high pressures and low temperatures (200 to ~500 degrees Celsius), approximately corresponding to a depth of 15 to 30 kilometers.
