Abstract

In the northern margin of Uludağ massif in northwest Anatolia, the Bursa Detachment having top-to-the north, northeast normal sense of shear separates the lower plate high-grade metamorphic rocks of Series-A (Uludağ Group) from the upper plate low-grade metamorphic rocks of Series-B (Karakaya Complex). The deeper section of Uludağ massif is represented by the Oligocene metagranites at the southern parts of the massif that is exposed due to the youngest high-angle Soğukpınar normal fault. The massif is a typical extensional metamorphic core complex similar to the counterparts in west and northwest Anatolia such as the Menderes, Kazdağ, and Çataldağ core complexes due to close timing of exhumation and a similar sense of shearing.
