Abstract:The stratum of Late Palaeozoic exist in Linxi region , Inner Mongolia of Greater Hinggan southern ar-ea.Dark and thick mudstone layer with potential conditions for hydrocarbon generation and reservoir in Linxi formation of Upper Permian develop well in this region.The feature of maceral , abundance , type and maturity of organic matter of Linxi formation is studied with the method of combining organic petrology and organic geo-chemistry together.The average level of determination of the organic carbon percentage is 0.61%, which shows abundance of organic matter in the mudstone is relatively high.Therefore , the mudstone of Linxi Forma-tion is better hydrocarbon source rock with highly producing ability of hydrocarbons.While the generation abil-ity of hydrocarbon in Linxi Formation mudstone should be gas because of the organic matter type of the mud -stone is mainly type Ⅲand the Organic matter maturity of the mudstone mainly belongs to the high mature to over mature evolutionary stage.
