Girazi rinoputika rakagadzirwa nenzira yedombo rakadirwa.
Iyo inoumbwa kana bota rinonzwa rakasimudzwa kubva mugomo rinoputika nekukurumidza nekukura kushoma kwekristaro.
Inogona kazhinji kuwanikwa kumucheto kwe rhyolitic lava inoyerera inozivikanwa se obsidian plumes, uko chemistry uye yakakwira silica zvemukati zvinokonzeresa viscosity yakakwirira iyo, kana yatonhodzwa nekukurumidza, inoumba yakasikwa lava girazi.
Kudzivirirwa kwekupararira kweatomu kuburikidza neravha inonamira iyi inotsanangura kushomeka kwekukura kwekristaro. Iro dombo rakaoma, brittle uye amorphous, saka rinoputika nemicheto yakapinza zvikuru.
