Studies have led to a general understanding of the first-order kinematics of the Franciscan subduction complex and the San Andreas fault system. However, there has never been an outcrop-scale study of the structures in the coastal exposure of Franciscan Complex in central California. The outcrops at this area of Highway 1, near the Sur Fault zone, contain abundant faults and slicken lines, and stand to offer invaluable information about the tectonic history of this area. Evidence for two superimposed deformations is present in the Franciscan rocks between Lopez Point and Ragged Point: a subduction related deformation and a strike-slip (Sur Fault) related deformation. My objective is to identify structural domains by comparing fault characteristics over an area representative of the structure between Lopez Point and Ragged Point. The timing of faulting can be constrained by approximately 30 igneous dikes, some cut by faults and some cutting faults, present near the Monterey-San Luis Obispo County line. Through analysis of these faults, the deformation from transform tectonics can be separated from that of subduction, and more can be learned about the transition between the two.
