Kimberlite is generally poor in the minerals most often found in igneous rocks because it forms at extreme depths. Rising from 100 to 135 miles under the surface, kimberlite magma tends to scrape other rock types from the walls of its chamber and incorporate them into its matrix. This process is responsible for its very rough, asphalt-like texture. Kimberlite samples sometimes contain garnets and diamonds, which also sets them apart from more common igneous rocks.
