Abstract
A reconnaissance study of potential hydrocarbon source rocks of Paleozoic to Cenozoic age from the highly remote New Siberian Islands Archipelago (Russian Arctic) was carried out. 101 samples were collected from outcrops representing the principal Paleozoic-Cenozoic units across the entire archipelago. Organic petrological and geochemical analyses (vitrinite reflectance measurements, Rock-Eval pyrolysis, GC-MS) were undertaken in order to screen the maturity, quality and quantity of the organic matter in the outcrop samples. The lithology varies from continental sedimentary rocks with coal particles to shallow marine carbonates and deep marine black shales. Several organic-rich intervals were identified in the Upper Paleozoic to Lower Cenozoic succession. Lower Devonian shales were found to have the highest source rock potential of all Paleozoic units. Middle Carboniferous-Permian and Triassic units appear to have a good potential for natural gas formation. Late Mesozoic (Cretaceous) and Cenozoic low-rank coals, lignites, and coal-bearing sandstones also display a potential for gas generation. Kerogen type III (humic, gas-prone) dominates in most of the samples, and indicates deposition in lacustrine to coastal paleoenvironments. Most of the samples (except some of Cretaceous and Paleogene age) reached oil window maturities, whereas the Devonian to Carboniferous units shared a maturity mainly within the gas window.

N1 - Funding information: The CASE-13 expedition was partly supported by Total E&P Russie and CASP . We used a few samples collected by other Russian participants of the CASE-13 expedition: Nikolay Sobolev, and Tatjana Tolmacheva (VSEGEI). Alexander Kuzmichev (Geological Institute of RAS, Moscow) and Viktoriya Ershova (Saint-Petersburg State University) also kindly shared their samples for these studies. Rock-Eval pyrolysis on VSEGEI's samples was performed with the help of Antonina Stupakova (Moscow State University). The organic petrography studies on VSEGEI's samples were carried out by Galina Volkova (VSEGEI). All these contributions are gratefully acknowledged. The BMBF/German Federal Ministry of Education and Research (Internationales Büro des BMBF) is gratefully acknowledged for the financial support of C. Brandes ( RUS 11/A09 ). Many valuable comments from anonymous reviewers greatly improved the manuscript.
