Abstract In order to invstigate the relationship between gold deposits and magmatic rocks or structures, the authors in this paper have analyzed the spatial relationship between magmatic rocks and gold deposits, the isotope characteristics of ore-forming fluids and the control effect of Tan-Lu fault zone on the gold deposits, after analyzing the gravity and magnetic anomalies to infer the distribution characteristics of hidden rock masses. The results show that most of the gold deposits are located on the edge of the known or hidden rock bodies and the deposits in the area have similar ore-forming fluids. Most of the quartz sample points fall into the magma water range in the H-O isotope diagram, and other points fall into the range of metamorphic water. The magmatic rocks provide an important material source for the formation of gold deposits and the intrusion of magma causes the activation of metamorphic rock series. The mixed fluid provides heat source for the migration and enrichment of the gold element, and activates the gold element during the formation of gold deposits. The ore-forming fluids migrate, enrich, and mineralize along the NNE-NE secondary faults of the main fault.

Key words： Wuhe area gold deposit magmatic rock ore-forming fluids Tan-Lu fault zone
