Abstract
This study provides a structural analysis of the Modoc zone. The Modoc zone is a shear zone in the southeastern-most portion of the Appalachian. This study investigates the structures within the Modoc zone and interprets the kinematics and deformation history of the Modoc zone. Previous studies investigated this region in South Carolina. The interpretations of deformation history in previous studies were projected westward into east and central Georgia. In this study, the focal point is the Modoc zone in eastern Georgia. The analysis of this study is compared to similar studies done in South Carolina. The Modoc zone’s present-day orientation is striking 235°-250° and dipping steeply to the northwest. The Modoc zone has experienced 3 deformation phases the Alleghanian orogeny outlined by previous work of Secor and others (1986a,b). Each of these phases is represented by structures and deformation fabrics formed as a result of the kinematics of terrane in the southern Appalachian. In this study, I analyzed the structures within the Modoc zone to investigate the deformation history of the shear zone. This study aims to provide structural analysis of the Modoc zone in eastern Georgia and compares the interpretations to the previous studies in South Carolina.
