Obsidian lan Adakite
Definition
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
adakite iku sawijining penengah kanggo felsic rock vulkanik sing nduweni ciri geochemical saka magma kang wis ngandika bakal kawangun dening leleh sebagean saka basalt ngrubah sing subducted ngisor busur vulkanik

nalika lahar dirilis saka gunung, iku diwiwiti saka cooling cepet banget kang freezes mekanisme saka crystallization. asil punika kaca vulkanik karo susunan Gamelan seragam.
rocks adakite sing kawangun nalika cairan hydrous sing dirilis saka mineral sing break mudhun ing basalt metamorfosis, lan munggah menyang lapisan, banjur padha salat leleh sebagean.
