The Transition from Solid-state to Magmatic Deformation in the Paros metamorphic complex, Paros Island, Greece
The project I worked on this summer was to look at the transition from solid-state to magmatic deformation in the Paros metamorphic core complex, Paros Island, Greece. I conducted field work on the island, mapping contacts, collecting strike and dips, lineations, fold axes, and boudin necks where available. I collected orientated samples from 18 outcrops along east-west and north-south traverses. From these, I made a selection of thin sections, which I then analyzed qualitatively for shear sense indicators, quartz c-axis orientation, and grain size and shape to asses the thermal gradient from the edge to the core of the complex. I also created a new map of the core complex with my data on it using some previously mapped contacts as well as new ones. I constructed north-south and east-west cross sections of the dome, using the apparent dips derived from my field measurements. As I did not have time to make, and analyze thin sections from each rock, more work needs to be done in order to better understand the thermal gradient.
