Abstract:

Based on the theory of rock mechnics, tectonic geology and the fracture structure features of Luojiazhai area, the palaeotectonic stress and crack distribution of T1 j42 bottom were studied and predicted by use of numerical simulation. The results show that crack and fracture were developed in Jialingjiang Formation and they were mainly distributed nearly faults, especially in the fault intersections and high structures.

Key words: lithology and paleogeography, depositional system assemblage, Lulehe Formation, northern margin of Qaidam Basin
