 Hi, my name is Owen Callahan. I'm coming to you from Freeman Ranch outside of San Marcos, Texas. I'm here scouting up locations for my structural geology class. The students will be out here measuring fault surfaces and striations on the fault surfaces to understand how rocks have moved past one another and understand some of the kinematics of the fault zones. I'm personally interested in fluid flow in faults and fractures. I'm interested in the interaction between how the orientations of faults influences the location of fluid flow and how fluids and resultant alteration and mineralization change the mechanical properties of faults and fractures. This has relevance for mineral deposits, but also for hydrothermal systems and geothermal energy, which is really where my big passion lies. So, thanks!
