Kalamaili area in the northeastern margin of Junggar Basin is an important gold deposit distribution area in China. The fault systems in the area are complex and play a significant ore-controlling role. At present, no scholars have studied the relationship between the fractal characteristics of faults and the distribution of gold deposits in this area.The spatial distribution law, development complexity degree and the control law of faults in different directions and scales in this area need be further studied. In this paper, the fractal dimension of the fault system in the study area is calculated at different scales and in different directions. The fractal dimension of all faults is 1.421, and the fractal dimension of faults is 1.382 in NW direction, 1.223 in NWW direction, 0.998 in EW direction and 0.960 in NE direction. The fractal dimension values of all faults and NW faults in this area are greater than the critical value of fractal dimension（1.22-1.38） that reflects the connectivity of geological bodie
