Obsidian vs Variolite
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
variolites iku sawijining klompok saka rocks peteng ijo dhasar igneous kang ngetokne bulak panggonan colored, utawa spherules, utamané ing lumahing weathered, sing menehi dheweke katon pockmarked
