Garnet schist typically has a dark red or burgundy color due to the presence of garnet minerals. It is a foliated metamorphic rock with layers of garnet crystals intermixed with other minerals like mica, quartz, and feldspar. Garnet schist often has a shiny appearance and is commonly used in jewelry and decorative applications.
Garnet schist-- as well as mica schist--can be found anywhere where clay rock with some calcite content-- such as siltstone or a mudstone, for example-- can be compressed (via metamorphism) and consequently sqeezed into rock-like layers.
Metamorphic rocks such as schist, gneiss, and some varieties of marble are likely to contain garnet as a common mineral. Garnet often forms in high-grade metamorphic environments where temperatures and pressures are elevated.

The birthstone color for January 10 is Garnet, which typically has a deep red color. Garnet is said to represent love, protection, and healing properties.
Regardless of the color of the garnet specimen, it would leave a white streak.
Mica and garnet are commonly found in schist. Chloride is not typically found in schist; rather, it is often associated with evaporites or in hydrothermal systems.
Garnet schist does not typically react with hydrochloric acid, as the garnet in the schist is a stable mineral that is not easily dissolved by acid. Schist is a metamorphic rock composed of minerals like mica, quartz, and feldspar that are generally resistant to chemical weathering.
Biotite, muscovite, chlorite, talc, garnet, and kyanite are common in schist.
The specific gravity of garnet schist can vary depending on the composition and density of the minerals present. On average, the specific gravity of garnet schist is around 2.7 to 3.2. However, it is recommended to measure the specific gravity of a specific sample to get an accurate value.

The mineral common in schist and gneiss but not common in slate and phyllite is garnet. Garnet typically forms in higher-grade metamorphic rocks such as schist and gneiss due to the increased temperature and pressure conditions necessary for its formation.
Metamorphic rocks such as schist, gneiss, and some varieties of marble are likely to contain garnet as a common mineral. Garnet often forms in high-grade metamorphic environments where temperatures and pressures are elevated.
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.
Sediments which are derived from some schist rock formations might contain garnet.
Garnet leaves no color in a streak test .
The mineral that fits this description is garnet. Garnet has a hardness of 6.5-7.5 on the Mohs scale, meaning it can scratch glass. It has a non-metallic luster, exhibits fracture rather than cleavage, and is commonly found in a dark red color.
