Depositional Cycles and Sr/Ba Ratio in Baku Regiostage Succession in the Western Flank of the South Caspian Depression

For the first time very detailed study (centimeter scale) of outcrop was carried out for stratigraphy and environment of the Lower Pleistocene deposits cropped out in the Western flank of the South Caspian depression (Shikhovo exposure). The data obtained demonstrated the high-frequency cyclicity in sedimentation accompanied by rapid lateral and vertical depositional environment change. Most of these system tracts have not yet been studied in detail. The depositional setting during accumulation of this succession has changed within shore face-shelf environment. On the background of these cycles, the depositional series of a higher order containing sediments deposited during very small-scale sea level fall and rise occur. Some information contained in this document is the new data, due to more recent observations and interpretations.
