Abstract: The mine geological characteristics，metallogenic geological conditions and deposit genesis of the Dongqiao antimony deposit are analyzed.Based on this，the mining geophysical and geochemicals anomalies characteristics of the mining area are summarized and interpreted.The results show that：①the surface geochemical scans show that，the Sb，Zn，Cu，As，Pb and Hg anomalies are existed in the mining area.Among these，the ore-forming geological conditions of comprehensive anomaly areaⅡare extremely advantageous，and the wall rock alteration is developed，several veins are found with wide abnormal range and high abnormal intensity.The abnormal morphology of Sb is distributed with circular in EW，with the maximum outliers of 252×10-6，and the average outliers of 37×10-6；②the concentration of the ore-forming elements such as Sb，Zn，Pb，Sn，Cu，Ag matches well with each other.The abnormal intensity of As and Hg are higher，and its abnormal center fit well with the anomaly center of metallogenic elements；③M2 magnetic anomaly distributes with scattered points and beaded form，they constitute near east-west bunch of anomaly，besides that，the M2 magnetic anomaly characteristics are consistent with the mineralization clues that are already found；④the average apparent polarizability of mining area is 2.746%，which shows the presence of sulphide.The ore-prospecting vision of the mining area is analyzed and the Genglongpo prospecting target area is selected based on the above geological，geochemical and geophysical information，which provides the guiding for ore-prospecting in the area.
