| Abstract: | Based on the work of 1/50 000 regional investigation and previous data, it was thought that the Xiaoyinuogaigou gold deposit is a post-ductile-shear type one formed from J_2 to K.The deformation characteristics of the Erguna tectonic zone, the regional magmatic activity, the host structures and the metallogenic geological characteristics related to the formation of the deposit was presented.It was considered that the formation of the Xiaoyinuogaigou gold deposit was associated with the closure and collision of the Mongolia-Okhotsk ocean,the intracontinental detachment-subduction resulted from the movement of the Pacific Plate,and with the deformation and tectonic deep-source-magmatic metallogenic hydrothermal activity. Finally , the metallogenic mechanism was discussed in line with the regional tectonic evolution. |
