Properties of Rhyolite Magma part of Cutting Edge:Petrology:Teaching Examples
The purpose of the exercise is to acquaint igneous petrology students with properties of silicic magmas, and to emphasize the effect of water content on viscosity of silicic magmas. Students have to determine the dimensions of a Quaternary rhyolite flow from a topographic map, employ a mineral thermometer to establish magma temperature, calculate density of the magma from its chemical composition, and use the Jeffreys equation relating flow velocity and viscosity.

Flow of Andesite Lava part of Cutting Edge:Petrology:Teaching Examples
The purpose of the exercise is to familiarize igneous petrology students with flow properties of lava, especially viscosity, and to have them consider effects on viscosity due to temperature, crystallinity and volatile content. The problem uses data from an actual eruption.

Yellowstone Thought Questions part of Cutting Edge:Petrology:Teaching Examples
These thought questions provide students the opportunity to critically think about features they see on a field trip through Yellowstone National Park.
