The study examines sediments of the Productive Series from the western South
Caspian Basin. The main goal of this work is to reconstract provenance of the
sediments and its relation to the climatic variability during the deposition of the
Productive Series. The Productive Series is divided into a lower and upper division.
The Russian Platform was the main sediment source area for the Lower Division.
Three different sediment source areas were determined for the Upper Division: the
Russian Platform was sediment source area for the Absheron Peninsula; the Greater
Caucasus was the main sediment source area for the South Absheron Offshore Zone
and the Lesser Caucasus was the main sediment source area for the Baku
Archipelago. The sediments of the Lower Division have variable smectite and illite
concentrations which indicate climate change between humid and arid conditions in the
Russian Platform. The Upper Division of the Productive Series from the Absheron
Peninsula is characterised by high amounts of illite. It suggests physical weathering
under arid climatic condition on the Russian Platform at the time of deposition.
Variation of the smectite and illite assemblages of the Upper Division from the South
Absheron Offshore Zone probably indicate that the climate alternated between humid
and arid conditions in the Greater Caucasus. The low amount of the TOC ratios in the
Productive Series are associated with arid climatic condition in the Russian Platform
and the Greater Caucasus. The much higher TOC/TN ratios (>35) indicate that
sediments of the Productive Series were impacted by oil. However the low TOC/TN
ratios (<12) in some intervals of the Productive Series suggest an aquatic source for an
organic matter.
