Abstract: The Shaanxi Xiaoqinling gold deposit belongs to quartz vein type gold deposit,the gold-bearing quartz veins represent the distribution and migration range of gold-bearing ore-forming hydrothermal fluids in the mineralization period. In this paper, the geological structure measurement of the dark-colored inclusion bodies in the Q1403 gold-bearing quartz veins has been measured by determining the occurrence of a-b-c axes and the attitude of long axis axial planes of inclusion, and the migration direction and channel of hydrothermal fluids in the Q1403 gold-bearing quartz veins have been comprehensively discussed. This study has a practical significance for deep exploration of gold deposits.
