picrite punika nggoleki-grained, hard rock 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.
nalika lahar dirilis saka gunung, iku diwiwiti saka cooling cepet banget kang freezes mekanisme saka crystallization. asil punika kaca vulkanik karo susunan Gamelan seragam.
