The Bahía Mansa Metamorphic Complex or BMMC (Spanish: Complejo metamórfico Bahía Mansa, CMBM),[2] also known as the Western Series,[3] is a group of metamorphic geologic formations of the Chilean Coast Range in southern Chile. It consists mainly of pelitic schists, metagreywackes and oceanic type mafic metavolcanics.[4] The complex owes its name to Bahía Mansa.
