Abstract

In the northern margin of Uludağ Massif in northwest Anatolia, the Bursa Detachment having topto- 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 the 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.
