P502 GEOCHEMICAL CHARACTERISTIC OF OILS AND MENILITE SOURCE ROCK IN THE POLISH FLYSCH CARPATHIANS D. WIECLAW M. J. KOTARBA AND A. KOWALSKI University of Mining and Metallurgy Faculty of Geology Al. Mickiewicza 30 30-059 Cracow Poland 1 SUMMARY Results of stable carbon isotope and biomarker analyses of 10 oils and 20 Oligocene Menilite source rock samples from the Polish Flysch Carpathians provide compelling evidence for a genetic relationship between them. Total organic carbon (TOC) content in the Menilite shales significantly vary from 1.73 to 12.2 wt. %. Maturity type II kerogen ranges between 0.4 and 1.7% in vitrinite reflectance scale
