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.
Wangun rock pumice nalika magma cools supaya cepet sing atom ing nyawiji sing ora bisa kanggo ngatur piyambak menyang struktur kristal.
