A schist is a metamorphic rock.
Gneiss is a metamorphic rock and its parent rock (protolith) could be a granite or schist.
Gneiss is a high grade metamorphic rock, the product of various rock types being exposed to intense pressures and heat under the surface of the Earth. Orthogneiss is a gneiss whose parent rock was igneous, and paragneiss is a gneiss whose parent rock was sedimentary.
The most widely distributed metamorphic rock is schist. Schist forms from the metamorphism of rocks such as shale or slate, and it is characterized by its foliated texture composed of platy minerals like mica. Schist is found in many regions worldwide, occurring in areas where regional metamorphism has taken place.
Hornfels or gneiss are possible metamorphic rock with a greywacke protolith.
Schist is a metamorphic rock.
A schist is a metamorphic rock.
A schist rock belongs in the metamorphic rock group.
No, schist rock does not bubble when in contact with hydrochloric acid because schist is a metamorphic rock composed of minerals like mica, chlorite, and quartz that do not react with acids to produce gas bubbles. Schist is typically more resistant to chemical weathering compared to other rock types like limestone or marble.
No, schist is a metamorphic rock type.
No Schist is not a crystal, but it is composed of minerals.
Generally not. Schist is a metamorphic rock formed when other rock types are exposed to immense pressure. If schist is found near a volcano, it is only by coincidence.
Schist is a high-grade metamorphic rock.

The Vishnu schist basement rock layer at the bottom of the Grand Canyon is roughly 1.8 billion years old.
