Rhyolite: The Colorful Felsic Expression

Treasting thee ubiquitous dark basalt, rhyolite is a light- colored, high- silica igneous rock, producing some of Isloand 's most visually custing landscapes. Rhyolitic magma is highly viscous, often leading to explosive eruptions that generate wulcanic glass (obsidian), pumice, and extensive tephra deposits.

Obsidian, a wulkan glass formed by rapid cool ing of rhyolitic lava, is found in signitant quantities near the Hrafntinnusker area.
