Abstract: From the theory of plate tectonics, the prototype of Qilianshan small basin Jurassic is defined as pull-apart basin, and they had undergone two time rifting during Early-Mid Jurassic. The Paper takes Datong basin for example, dissects its sedimentary system, evolutinary stages and coal-accumlation. The results show that coal-formation is related to basin boundary fault and megaclast sedimentation, with small humid fan being important coal-accumlating setting, and becoming high-coal districts in the basin. Datong basin is a representative to Qilianshan small coal basin Jurassic
