Explosive volcanic eruptions.
Composition & Appearance:
It is light in color, often gray, bluish-gray, or pink, and primarily composed of quartz, K-feldspar, and biotite. Its fine-grained texture means the crystals are often too small to be seen without magnification.
Properties:
Rhyolite is a hard rock with a high silica content (69% or more), giving it its light color.
Uses:
Due to its hardness and other properties, rhyolite is used in various industries, including construction (as aggregate and for roofing shingles), landscaping, and even jewelry.
Occurrence:
It is found in areas with volcanic activity and can form features like lava domes or be found as rounded pebbles on beaches due to erosion and transportation.
