Abstract
Heicigou gold deposit is located in the midwest of Tuolaishan metallogenic belt. Fractures and secondary structures with the trend of NWW, NW and nearly NE are well developed in the area with good geological background of mineralization. In order to identify metallogenic geological conditions and expand the prospecting prospects, by using the combination of IP ladder measurement and prospecting project, 8 altered bodies and 13 gold ore bodies have been circled. Among them, No. 5 ore body is the main ore body in the area. The gold grade is (1.05～3.42) ×10-6 and average grade is 1.59×10-6. The ore bodies are lenticular and vein-shaped, and their attitudes are basically the same as those of the fracture structural alteration zones. The ore-bearing rocks are tuffaceous cataclastic rocks and structural breccia. The wall rocks are foliated tuff and andesitic tuff of early Ordovician Yingou group. The wall rock alteration is mainly silicification, pyritization, carbonation and ferritization. On the basis of expounding geological characteristics of Heicigou gold field, prospecting indicators and ore-controlling factors have been summarized, and prospecting prospect has been analyzed.关键词
