tatanan
peridotites bisa kawangun ing rong cara: minangka rocks lapisan kawangun sak accretion lan diferensiasi saka bumi utawa minangka rocks cumulate kawangun dening udan saka olivine lan pyroxenes saka magmas basaltic.
kenyte punika, hard rock nggoleki-grained kang jinis metasomatite, ateges ngrubah basalt. iku formulir karo utawa tanpa crystallization, salah siji ngisor permukaan minangka rocks intrusive utawa ing lumahing minangka rocks extrusive.
