 Luxi Complex, also known as the Luxi granite-greenstone terrane in western Shandong, contains gneiss and sheets and lenses of metamorphosed ultramafic-mafic volcanic rocks (greenstone).Metamorphosed komatiite was discovered as serpentinized peridotite and schist with spinifex texture.Such texture is interpreted to be associated with a basaltic volcanic activity 2.74 billion years ago.
