- Аннотация: A reconnaissance study of potential hydrocarbon source rocks of Paleozoic to Cenozoic age from thehighly remote New Siberian Islands Archipelago (Russian Arctic) was carried out. 101 samples werecollected from outcrops representing the principal Paleozoic-Cenozoic units across the entire archipel-ago. Organic petrological and geochemical analyses (vitrinite reflectance measurements, Rock-Eval py-rolysis, GC-MS) were undertaken in order to screen the maturity, quality and quantity of the organicmatter in the outcrop samples. The lithology varies from continental sedimentary rocks with coal par-ticles to shallow marine carbonates and deep marine black shales. Several organic-rich intervals wereidentified in the Upper Paleozoic to Lower Cenozoic succession. Lower Devonian shales were found tohave the highest source rock potential of all Paleozoic units. Middle Carboniferous-Permian and Triassicunits appear to have a good potential for natural gas formation. Late Mesozoic (Cretaceous) and Cenozoiclow-rank coals, lignites, and coal-bearing sandstones also display a potential for gas generation. Kerogentype III (humic, gas-prone) dominates in most of the samples, and indicates deposition in lacustrine tocoastal paleoenvironments. Most of the samples (except some of Cretaceous and Paleogene age) reachedoil window maturities, whereas the Devonian to Carboniferous units shared a maturity mainly within thegas window.
