  • Rhyolite - Wikipedia
    Rhyolite ( ˈraɪ əlaɪt RY-ə-lyte) [1][2][3][4] is the most silica -rich of volcanic rocks It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass The mineral assemblage is predominantly quartz, sanidine, and plagioclase It is the extrusive equivalent of granite Its
  • Rhyolite Rock | Properties, Composition, Formation, Uses
    Rhyolite is an acidic (felsic) composition, extrusive igneous rock This definition is correct but incomplete More accurately, rhyolite is: A rock that has the same chemical origin as granite But formed under completely different conditions And therefore developed completely different textures The difference between granite and rhyolite is not “what it is” but where and how quickly it

  • Rhyolite: The Fine-Grained Volcanic Rock - Rockhounding Wiki
    Rhyolite is an extrusive igneous rock formed from the rapid cooling of high-silica magma at or near the Earth's surface during volcanic eruptions It is the volcanic equivalent of granite, sharing a similar chemical composition but differing in texture due to its formation process While granite forms underground (intrusive), rhyolite solidifies from lava above or near the surface, which cools

  • Rhyolite - an overview | ScienceDirect Topics
    Rhyolite is extrusive equivalent of granite magma It is composed predominantly of quartz, K–feldspar and biotite It may have any texture from glassy, aphanitic, porphyritic, and by the orientation of small crystals reflecting the lava flow There is distinct porphyritic texture characterized by sanidine and rare quartz, plagioclase and biotite
