摘要: The Oligocene – Miocene Maikop Series is a world‐class source interval and the most important rock for petroleum systems of South Caspian Basin surrounding region. thick (up to 3 km) succession silty mudstones with intervals high organic carbon content. However correlation organic‐rich within beyond basins Eastern Paratethys problematic. Current age constraints are based primarily on microfaunal assemblages, but assemblages lacking in precision sparsely dispersed. This study provides numerical datum Maikopian strata that may be used improve both locally regionally. date obtained was produced via Re‐Os isotope geochronology. Of five sample suites analyzed, one data‐set yielded an isochron 17.2 ± 3.2 Ma. data sets failed produce statistically meaningful isochrons provide qualitative by comparing calculated initial 187Os/188Os ratios from these samples to187Os/188Os seawater through time.
