Rhyolite Rock Properties

Properties of the igneous rock rhyolite
Light in color there it is classified as felsic

Rhyolite contains over 70% silica which gives this rock it a light color
Because the crystals are so small it is an extrusive igneous rock and cooled quickly
in rhyolite the crystals are often too small to see. This is due to the rapid cooling of the rhyolite lava
Rhyolite is produced by violent volcanic eruptions.
Density 2.4 -2.6 g/cm3
The texture of Rhyolite is fined grain and is classified as aphanitic
In summary
