Abstract: 

The Devonian sediments from the Moesian Terrane (Moesian Platform, northern Bulgaria) are known only from oil and gas prospecting wells. Middle and Upper Devonian deposits are interpreted as formed in great variety of depositional settings. Thus, the Eifelian carbonates were regarded as inner- and mid ramp deposits developed in a shallowing-upward sequence. The shallowing tendency continued during the Givetian and Frasnian, when arid tidal-flat and lagoon settings predominated. At the beginning of the Famennian, a climate change occurred when the Moesian Terrane was removed from the Subtropical Arid to the Warm Temperate Climatic Zone. Then, carbonate deposition took place in various shallow- to deepermarine environments.
