Currently I am interested in determining the spatial distribution of stresses related to orogenesis. Paleo-stress orientations and magnitudes can be calculated from crystallographic c-axis and twin lamellae of calcite using a petrographic microscope equipped with a universal stage. I am using this technique on a suite of limestones collected within and at varying distances from the Appalachian Mountains. This study will help confine the rheologic behavior of the crust and contribute to modeling of large scale tectonic deformation.
