Abstract

The Gulf of Izmit is a broad shear zone that developed by a series of linked pull-apart systems opened across west-northwest striking normal fault sets. These faults have become largely deactivated possibly sometime in the Quaternary and were sliced across by a long, east-west, throughgoing fault that hugs the shore between Golcuk and Karamursel and then jumps northward into the Gulf, clips the tip of the Hersek Peninsula, and strikes west probably to join the Marmara Fault postulated by Le Pichon, Taymaz and Sengor.
