What is garnet schist's protolith?
Garnet schist's protolith is typically a type of shale or mudstone. These sedimentary rocks undergo metamorphism under conditions of increased temperature and pressure, leading to the formation of schist with garnet as a prominent mineral. The process involves recrystallization and the alignment of platy minerals, resulting in the characteristic foliation of schist.
Which metamorphic rocks are likely to contain garnet?
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.
What rock would be the best source of the mineral garnet?
Garnet is a mineral, of the Al SiO3 community, with other contributions as well. Some times used as a minor gemstone. A cubic mineral, found often enough in metamorphosed rocks such as schist.
Is graphite commonly found?
Yes, graphite is commonly found in nature. It is a mineral form of carbon and can be found in rocks and ores, particularly in metamorphic rocks like marble and schist. Graphite is often mined and used for various applications, such as in pencils, lubricants, and batteries.
What is the most common type of metamorphic rocks in Death Valley?
The most common type of metamorphic rock in Death Valley is schist, particularly due to the region's complex geological history involving high temperatures and pressures. Schist is characterized by its well-developed foliation and can contain minerals such as mica, quartz, and garnet. Additionally, other metamorphic rocks like gneiss and marble can also be found, but schist predominates in this arid landscape.

Which mineral is commonly found in the three metamorphic rocks slate schist and gneiss?
The mineral commonly found in all three metamorphic rocks slate, schist, and gneiss is mica. Mica is a group of minerals known for their perfect cleavage, flexibility, and mineral composition, which make them prevalent in metamorphic rocks.
What mineral is common in schist and gneiss but not common is slate and phyllite?
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.

What rocks make schist?
Schist comes from shale. It is laminated , flaky, and found in parallel layers. The minerals in this rocks that have crystallized from the parent rock are visible.

Where do you find Garnets?
Garnets can be found in many places around the world, including India, Brazil, Australia, and the United States. They are typically found in metamorphic rocks, such as schist and gneiss, as well as in some igneous rocks. Garnet mines and deposits can also be found in riverbeds and along coastal regions.
Where is biotite most commonly found?
Biotite is most commonly found in igneous and metamorphic rocks. It can be found in granite, schist, and gneiss, among other rock types. Biotite is also often present in some sedimentary rocks, such as some sandstones.
Which mineral is commonly found in the three matamorphic rocks slate schist and gneiss?
granite
The most common form of Mica accuring in various rocks including Gneiss Granite and Schist?
The most common form of mica found in rocks like gneiss, granite, and schist is biotite. Biotite is a dark-colored mica mineral that is often found in igneous and metamorphic rocks, imparting a shiny appearance to the rock surfaces. It is known for its thin, sheet-like structure and is commonly associated with other minerals in these types of rocks.
