Discuss Kinetics and thermodynamics of the Spinel to Garnet Transformation

This paper is for my geochemistry of ore deposits class, so it involves both chemistry and geology. This is a case study, so focus on the experiments in the papers by Klemme and Nagayoshi, and what interpretations were made from these studies including pressure and temperatures constraints (p-t diagrams), and any other info on kinetics or thermodynamics. Focus more on garnets, and focus on thermodynamics and kinetics of the transformation between garnets and spinel. The other papers should provide general info on kinetics and thermodynamics of garnets.
