What’s The Garnet sand

Garnet is an important silicate rock-forming mineral and occurs in many rock types. However, it almost never makes up the majority of the rock’s mass. The same is true with a garnet-bearing sand. Garnet is a common mineral in sand but usually in low quantities. There are some hard to find exceptions – red and very beautiful sand where garnet is indeed the most abundant sand-forming mineral. Source rocks of garnet is usually either metamorphic (garnet schist, rarely eclogite) or igneous (aluminum-rich granite). Garnet sand is a sub-type of heavy mineral sand.
