Abstract：The organic facies of the Jurassic coal measures in the Turpan-Hami and Junggar Basins were clas-sified in detail. The mudstone organic facies and the coal facies were individually classified into 4 types. Basedon the Py-GC experiment of gas-generating potentials of the samples, some important indexes, such as Co1,Co2 ,Cg1 ,Cg2 ,D11 and D22 were put forward to reflect the gas-generating potentials of source rocks. Accordingto the fluorescence maceral index (FMI), the clay and coal source rocks were classified into 3 types, improv-ing and perfecting the organic petrology-organic geochemistry evaluating system for gas source rocks. Ac-cording to the evaluation of gas-generation potential of each organic facies, both at present and in the future,the favorable gas-generating belts were lined out. The results show that there is a coincident relationship be-tween the favorable gas-generating belts and the gas-accumulating belts.
