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
sak impact sing ilang materi mbentuk breccia ngemot kaca lan kristal utawa pecahan lithic bebarengan mbentuk rock suevite.
