Paleocene-Eocene deposits in the Nakhchivan region of Azerbaijan, central part of the Lesser Caucasus, Talysh and South-East Caucasus strongly differ by their depositional environment and lithology. They are also easily recognized in the field from underlying and overlying deposits by the color and lithological composition.

One of the peculiarities of Eocene series in the Lesser Caucasus and Talysh is a presence in the section thick volcanic deposits, which differentiates them from synchronous deposits in the South-East Caucasus where flish formations are widely occur.

Another problem is that in the different regions a volume of the stratigrafic units is different, corresponding to either several stages or to part of the stage.

In this paper two new suites have been determined – Daridag and Gilycmchay Suites, as well as all suites are subdivided into stages and correlated based on the new stratigraphic scheme for the first time.
