Schist

Schist is a medium-grade metamorphic rock with medium to large, flat, sheet-like grains in a preferred orientation.‎ It is defined by having more than 50% platy and elongated minerals, often finely interleaved with quartz and feldspar.‎ These lamellar minerals include micas, chlorite, talc, hornblende, graphite, and others.‎ Quartz often occurs in drawn-out grains to such an extent that a particular form called quartz schist is produced.‎ Schist is often garnetiferous.‎ Schist forms at a higher temperature and h

Types of Rocks and the Rock Cycle: Igneous, Sedimentary, Metamorphic - FreeSchool

Rocks are awesome!‎ They can be found everywhere on earth and come in many different shapes, forms, and textures.‎ There are three main types of rock: igneous, sedimentary, and metamorphic.‎ Learn more about these types of rock, how they are formed, some examples of each type, and how the rock cycle works to change one type of rock into another.‎ Like this video if you want to see more videos about GEOLOGY!‎ Subscribe to FreeSchool: https://www.youtube.com/user/watchfreeschool?sub_confirmation=1 Visit us on F
