The garnet group of nesosilicates is commonly found in metamorphic rocks and more rarely in igneous rocks , and the metal cations that are typically found in garnet minerals include aluminum, calcium, chromium, magnesium, manganese, and iron .
Where are silicate minerals found?
The silicates make up about 95 percent of Earth's crust and upper mantle, occurring as the major constituents of most igneous rocks and in appreciable quantities in sedimentary and metamorphic varieties as well. They also are important constituents of lunar samples, meteorites, and most asteroids.
