Abstract: The Jienagepu gold-antimony deposit is founded recently，which is located in the east antimony and gold metallogenic belt of southern Tibet detachment system.The Jienagepu gold-antimony deposit has 12 ore-bodies，which are occurred as veins-type,they are developed in the jurassic continental heat group formation and mainly controlled by faults significantly.They are 50~240 m long，0.34~8.83 m thick.The ore-types are divided into hydrothermal vein-type and altered rock-type,hydrothermal vein-type ore mainly contains stibnite quartz-calcite veins and gold quartz veins;altered rock-type ore is brecciated structure latered slate and alteration of intermediate-basic rock mass.Based on filed geological investigation and systematic study of geological background in the mining area,the geological characteristics,mineralization characteristics and mineral deposits genesis in the mining area are analyzed in depth,the ore-controlling factors in the mining area are also discussed from the aspects of strata and tectonic,the results show that:①the Ridang and Weimei stratum besides the mining area contain a large number of Au and Sb,which maybe the source of Jienagepu gold-antimony deposit;②in the early period,the intermediate-basic rock mass provide the ore-forming materials sources that cannot be ignored,in the late period,the intermediate-acidic rock mass provide the ore-forming enough power sources，which indicated that the deposits in the mining area are hypabyssal hydrothermal-type gold-antimony deposit with low temperature.Based on the above analysis results,the prospecting indicators of the mining area are summarized systematically,they are structure and geochemical anomalies combination indicators,geophysical anomalies indicators,wall rock alteration combination indicators and Au-As-Sb combination indicators.The research results in this paper can provide reference for the further prospecting exploration work and the research of regional gold-antimony metallogenic theory.
