Based on the objective analysis of field and laboratory data, the authors suggest that the Heqianzhuang anticline in which the large-scale Yindongpo Au deposit is located as well as the various strike-slip shear faults, strike-slip normal faults and thrust faults developing in the higne and limbs of the anticline formed after the formation of main ore protolith, and had no ore-controlling significance as previous work suggested. The structure formation se-quenoe is as follows: Heqianzhuang anticline→ore-hearing conjugate strike-slip faults→no ore-hearing conjugate strike-slip faults→strike-slip normal faults→thrust fault series. All these stractures, except for ore-hearing conjugate strike-slip faults, transformed the ore bodies with Heqianzhuang antidine's constructive and other structures' destructive processes.
