Explain how the percentage of silica in magma increases during crystallization despite the fact that silicate minerals are being removed throughout the crystallization process.
Fractional Crystallization of Magma Objective In this exercise, you will gain an understanding of magmatic differentiation by fractional crystallization using a model magma chamber. The activity was adapted from materials developed by Dr. Karl Wirth at Macalester College (http://www.macalester.edu/geology/wirth/CourseMaterials.html) Introduction In lecture you learned about the importance of fractionation in generating the diversity of observed […]
