Abstract

In order to evaluate the paleotectonics of the Mesozoic sediments in the Yalama-Khudat uplift zone, lithofacies and tectonic activity index were used. Representation of lithofacies with more accurate data and digital values of thickness data help to obtain realistic results about paleotectonic development. In the study, the tectonic development of the Yalama area was evaluated based on geological data. Although the decrease of tectonic activity continued towards the end of the Cretaceous, the repetition of lithofacies can be explained by the repetition of marine transgression and regression processes in the same area. The paleotectonic accumulation conditions of the Cretaceous sediments had their influence on the oil-gas generation and collector characteristics of the sediments. Keywords: Paleotectonic analysis; Lithofacies features; Sediment accumulation rate; Tectonic activity.
