Causes and Prospecting Marks of Dagoucao Gold Deposits in Xunyang County, Shaanxi Province

Dagoucao gold deposits in Xunyang county is a new breakthrough for polymetallic mineralization prospecting in the Qinling orogenic belt in recent years.In this paper, take the mining geology as the starting point, we analyzed the geological structures of deposits, ore-bearing wall-rock alteration, mineral characteristics, genesis, ore-controlling factors, etc., and proposed that the large trench cause of gold deposits is a hydrothermal sedimentary origin-transformation type gold deposits, and summarized the prospecting marks.
