摘　　要：为查明受断层破碎带控制的夺儿贡玛矿区下一步找矿方向,在矿区采用土壤地球化学测量、1∶1万综合剖面测量与槽探等验证方法,并对元素分布、元素相关性、元素异常等特征进行研究。研究发现:①Sb、Au为本区成矿潜力大的优势成矿元素,As、Cu、Pb、Zn、Ag为与Sb、Au矿化关系密切的重要找矿指示元素。②新发现4处蚀变岩型破碎蚀变脉,圈定了3条锑工业矿体。③初步查明本区主要为破碎蚀变岩型锑金矿床,受断层破碎带控制。结合矿区所处成矿条件和异常发育情况,建议在外围开展1∶1万土壤测量,扩大找矿成果。For purpose of find out the metallogenic regularity of the broken and altered deposit in Duoergongma area,which is controlled by fault fracture zone,verification methods were adopted,such as soil geochemical survey,1∶10000 comprehensive profile survey and trough exploration,and studied the characteristics of element distribution,element correlation and element anomaly.①Sb and Au are the dominant ore-forming elements with great metallogenic potential,and As,Cu,Pb,Zn,Ag are the important ore-prospecting indicator elements closely related to Sb and Au mineralization.②Four broken alteration veins of altered rock type have been discovered,and three antimony industrial orebodies have been delineated.③It is preliminarily identified that this area is mainly a broken alteration rock type antimony-gold deposit controlled by fault fracture zone.Combined with the metallogenic conditions and abnormal development of the mining area,it is suggested to carry out 1∶10,000 soil survey in the periphery to expand the prospecting results.
