Schist and slate are very similar in that they are made from the same rock types except it is subjected to more heat and pressure.

Large crystals of granite surrounded by mica schist.

The most common porphyroblasts in metapelites metamorphosed mudstones and siltstones are garnets and staurolites which stand out in well foliated metapelites such as schists. Mica is made up of thin sheet like layers of atoms that reflect light like a mirror. Large crystals cause schist rocks to reflect lots of light which gives it a very shiny appearance. The mountains are primarily composed of granite surrounded by an envelope of mica schist and much older rocks such as quartzite.

Mica crystal healing properties information. It has mica grains large enough to see with the naked eye which means it glitters and sparkles. Schist is a metamorphic rock made mostly of mica mineral formed under the heat and compression of tectonic forces. The black gray and white grains are mostly silt or smaller size grains of quartz and feldspar.

A porphyroblast is a large mineral crystal in a metamorphic rock which has grown within the finer grained matrix porphyroblasts are commonly euhedral crystals but can also be partly to completely irregular in shape. They were pushed up during the caledonian orogeny at the start of the devonian period and form part of the leinster chain the largest continuous area of granite in ireland and britain. Hi kevin my understanding is schist is a coarse grained metamorphic rock that consists of layers of different minerals mica among them along with chlorite talc hornblende and graphite and can be split into thin irregular plates. The large black grain is the garnet the red elongate grains are mica flakes.
