Geology Of The Kurucaşile - Cide Region, Nw Türkiye, Okan Tüysüz
Bulletin of the Mineral Research and Exploration
The lowest unit of the Cide-Kurucaşile region is the Carboniferous coal-bearing terrestrial sediments. Permian aged terrestrial Çakraz Formation and the Triassic lacustrine Çakrazboz Formation unconformably overlie the Palaeozoic sequence. Dogger-aged Himmetpaşa Formation represents a short-period marine invasion. The transgression started in the Kimmerician has led to the development of a carbonate platform, which has risen and demised after the Berriasian. A second carbonate platform, much more limited than the previous one, developed in the Late Barremian, and then the whole region deepened. The Cenomanian is a period of regional uplift and erosion. The first effective volcanic activity in the region …
