Early Devonian transgression in the Eastern Antalya Nappes: conodont data from the Tahtalidag Nappe, north of Alanya, southern Turkey

WA Museum Records and Supplements | Updated 9 years ago

Abstract - The second carbonate level in the Guneyyaka Formation of the Ovacik and Gundogmus slivers of the Tahtalidag Nappe (eastern Antalya nappes, southern Turkey) have been dated by conodonts as late early to middle Lochkovian (Early Devonian). Previous interpretations where the Guneyyaka Formation begins in the Late Silurian and represents continuous deposition through to the Middle Devonian, are not confirmed. An earliest Devonian transgression post-dating a pronounced Silurian-Devonian boundary hiatus is also recorded in the Tahtalidag Nappe. There is little thermal alteration of sediments deposited in the Karaburun-Boikardag Ocean on the Perigondwanan shelf to the south during the Caledonian time interval.
