1. Rhyolite

   Rhyolite ( RY-ə-lyte) 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 to granite. Rhyolitic magma is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment.

1. rhyolite

   Rhyolite is a type of igneous rock, formed from cool, hardened magma or lava. It is typically light in color due to its high silica content, and it often contains minerals such as quartz and feldspar. Rhyolite is similar in composition to granite but tends to form under different geological conditions. It can often be found in areas with volcanic activity and is known for its fine-grained or glassy texture.
