Petrography and Petrogenesis of a Mid-Ocean Ridge Lava Suite part of Cutting Edge:Petrology:Teaching Examples
This activity is designed to accompany a set of thin sections available from the authors. Students investigate mid-ocean ride basalt petrography and relate observed mineralogic changes to relevant phase diagrams and major element chemical evolution. Using this information and data provided on the tectonic location of the samples they develop hypotheses regarding the petrogenesis of the suite.
