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.

yes it is many people think it is an igneous rock because it is red
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.
Minerals commonly present within skarn rocks include garnet, magnetite and epidote.

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.

Schist is commonly used in building buildings. However foundation issues occur and it is not safe to use anymore. The joints weaken and crumble so this is no longer a practical use.
Schist is a high-grade metamorphic rock.
