In view of types,abundances and thermal evolution properties on organic matter,an evaluation of the hydrocarbon source rocks of the lower and middle Jurassic in Tula basin is made.

On the basis of biomarkers in the lower and middle Jurassic source rocks from the Tula basin,it can be seen that these samples at least have reached maturation stage during their thermal evolution,and the organic sources are mainly from terrestrial higher plant combined with abundant aquatic organisms input.

Tula basin is located among the southwestern Qaidam basin,the southeastern Tarim basin and the north of Kekexili mountain ranges,with above sea level of3000meters,being sparsely populated and very low mature explo-ration.
