As another large gold deposit discovered recently, the Changan gold deposit is located in the southern section of ailaoshan belt . The area is the edge of the crust Ailaoshan terrane accretion zone , mainly composed of metamorphic rocks. There are many faults in the region, and they has a significant impact on the magmatism and mineralization . Based on a lot of literature and the exploration report , the geological characteristics of Changan gold deposit has been summarized in this paper. We took F6 fracture of the area as the main research goal, with lithology electrical characteristics as constraints . A lot of methods in this study contain magnetic survey,IP,TEM and EH 4. The results show that magnetic survey isnt suitable to the Changan gold deposit, but the resistivity inversion sections of TEM and EH 4 methods can reflect clearly the location,orientation,fracture width of F6 and so on. And we can determine the position of the orebody by IP anomalies. So combined with TEM,EH 4,IP and soil geochemical methods in the next work, it will be very helpful for prospecting deep concealed ore.
