This article is the second one of the series of publications on the stratigraphy of the Nakhchivan Autonomous Republic. The work that is based on the modern International Chronostratigraphic Chart concisely differentiates and describes local sequences and grounds palaeontologically the local stratigraphic sub-divisions. It also offers the palaeogeodynamic and palaeogeographic factors that had stood behind the formation of the various Mesozoic structural substance complexes that contribute to the geological constitution of the area covered. Those data, published in English for the first time ever, add up to a rich lithology and stratigraphy database on the Triassic, Jurassic and Cretaceous pericontinental sediments of the Araz Structural Megazone, that is, the NW Block of the South Azeri Segment of the Central-Iranian Microcontinent. Such data as contained in this work can safely be used by overseas geologists interested in the South Caucasian geology and stratigraphy to underpin regional generalisations and stratigraphic correlations of the Mesozoic sequences.
