Aug 10, 2019 · Feldspars usually are white or nearly white, though they may be clear or light shades of orange or buff. They usually have a glassy luster. Feldspar is called a rock-forming mineral, very common, and usually makes up a large part of the rock. In sum, any glassy mineral that's slightly softer than quartz is very likely considered a feldspar.

Rhyolite rocks bear a striking resemblance to granite, due to being classified as felsic rocks, except that rhyolite has a fine-grained texture with phenocrysts, which are small crystals sometimes embedded within the rock. The minerals that make up the composition of this rock are mica, feldspar, quartz.

10.04.2010 · Quartz, feldspar and mica are some of the most abundant minerals in the earth's crust. Quartz (SiO2) is present in almost all rocks. It is hard, resistant to chemical weathering and has no cleavage, which means it is also resistant to physical weathering. It is abundant in silica-rich igneous rocks, like granite and rhyolite.

Schist (pronounced / ʃ ɪ s t / SHIST) is a medium-grade metamorphic rock formed from mudstone or shale. Schist has medium to large, flat, sheet-like grains in a preferred orientation (nearby grains are roughly parallel). It is defined by having more than 50% platy and elongated minerals (such as micas or talc), often finely interleaved with quartz and feldspar.
