Yaogou Gold Deposit is located at the junction of middle part at the north rim of North China Plate and Khingan-Monglia orogenic belt,which belongs to northeast section of Chifeng-Chaoyang gold metallogenic belt.The ore bodies in the mining district is located in the fault system on caldera,and the main ore-hosting wall rock is rhyolitic rock debris crystal tuff in Yixian Formation;complete homogeneous temperature of quartz fluid inclusions is 159 ℃-245 ℃,the salinity is 1.22 %-11.72 %,indicating low salinity and medium low temperature hydrothermal features,and that the deposit is volcanic rock type gold deposit.The  interpretation of remote sensing anomalous information shows that Yaogou Gold Deposit is highly concentrated hydroxyl anomalies.1∶50 000 stream sediment survey has delineated comprehensive anomalies dominated by Au.1∶10 000 soil geochemical survey has discovered the soil comprehensive anomalies dominated by Au and Ag within the anomalous belt.Both are important geochemical prospecting marks.1∶50 000 airborne magnetic anomaly is low negative magnetic anomalous.1∶10 000 high precision magnetic survey shows that ore-hosting faults are characterized by low magnetism,1∶10 000 induced electric anomalous is charac-terized by high polarization rate and low electric resistivity,which can be used as geophysical prospecting marks.The setting of the geological,geophysical,geochemical and remote sensing comprehensive information prospecting marks provide prospecting reference to look for similar volcanic rock type gold deposits in the district.
