Tatanan

tatanan
anorthosite punika phaneritic, intrusive rock igneous kang ditondoi dening predominance saka plagioclase Feldspar kang meh 90-100%, lan komponèn mafic tithik.   
websterite bisa kawangun minangka cumulates ing intrusions ultramafic dening klempakan saka kristal pyroxene ing dasar ing kamar lahar.
