This is because, geologists once called basalts basic rocks. Compared with metasandstones and metapelites, metabasites are relatively poor in Al and Si and rich in Ca, Mg, and Fe. Many different minerals may form, and metamorphic reactions are complex.Metamorphosed basalts and other rocks of similar composition are commonly called metabasites.
