Liparite vs. Rhyolite — What's the Difference?

(mineral) A quartzose trachyte; 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 rock.

A quartzose trachyte; rhyolite.

A fine-grained extrusive volcanic rock, similar to granite in composition and usually exhibiting flow lines.

(geology) An igneous, volcanic (extrusive) rock, of felsic composition, with aphanitic to porphyritic texture.

A quartzose trachyte, an igneous rock often showing a fluidal structure.

Very acid volcanic rock
