Triassic black mudstones are extensively distribut ed in Tarim basin with great thickness and higher content of total organic matte r (TOC) and extractable organic matter (EOM). Abundance pregnanes and higher con centrations of tricyclic terpanes are also observed in extractable organic matte r (EOM) of Triassic source rocks. All of above characteristics show that organic matters in Triassic source rocks of Tarim basin are rich in aquatic-life deriv ed organic material and Triassic source rocks are favorable for oil and gas gene ration. Triassic source rock organic matters are also mature in thermal maturity in most parts of Tarim basin. The oil/gas and source rocks correlation studying have proved that considerable amount of oil and natural gas produced in Tarim b asin are derived from Triassic source rocks. Triassic source rocks are in good c ondition with relatively higher potential for oil and gas generation.
