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。
Abstract: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∶10 000 comprehensive profile survey and trough exploration, and studied the characteristics of element distribution, element correlation and element anomaly. ① Sb 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. ② Four broken alteration veins of altered rock type have been discovered, and three antimony industrial orebodies have been delineated. ③ It 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.
