definisi
obsidian punika kaca vulkanik alami kawangun minangka rock igneous extrusive. diprodhuksi nalika lahar felsic extruded saka gunung mbledhos ndingin kanthi cepet karo wutah kristal minimal
a hidrasi lan transformasi metamorphic saka ultramafic rock saka lapisan bumi diarani minangka serpentinization, klompok mineral wis kawangun dening serpentinization nyipta 'serpentinite' rock.
Etimologi
saka obsidianus latin, misprint saka obsianus (lapis) (watu) saka obsius

tatanan
nalika lahar dirilis saka gunung, iku diwiwiti saka cooling cepet banget kang freezes mekanisme saka crystallization. asil punika kaca vulkanik karo susunan Gamelan seragam.
amarga kanggo ngganti ing kondisi lingkungan, rocks sing digawe panas lan pressurized jero nang permukaan bumi. serpentinite kawangun saka panas nemen disebabake magma utawa dening tabrakan kuat lan gesekan lempeng tektonik.
