Some oceanic structures, such as the Kerguelen Plateau and the Agulhas Plateau are mostly comprised of this rock.
Some oceanic structures, such as the Kerguelen Plateau and the Agulhas Plateau are mostly comprised of this rock. The accumulation of olivine and pyroxene in areas where this rock is formed can lead to the creation of Harzburgite. This rock has the same crystal structure, but is more mafic than (*) diorite. Both the Emeishan Traps in Sichuan and the Deccan Traps in India are comprised of successive "floodings" of this rock.
