摘要:

永新金矿床是黑龙江省多宝山外围地区近年来新发现的浅成低温热液型矿床,目前矿床规模已接近大型。在该矿床的发现及评价过程中,土壤地球化学测量工作起到了重要作用。研究表明,该矿床具有明显的土壤地球化学异常,1/5万土壤异常的元素组合主要为Au、Ag和Bi,其中,Au异常面积达1.5 km2。1/ 1万土壤异常分带现象明显,元素组合为Au、Ag、As、Sb、Bi、Cu、Pb、Zn、Mo和W,其中Au元素异常最大值为191.9×10-9,平均值为26.3×10-9。金矿化蚀变带的赋存部位、展布方向、规模产状与各元素的异常特征一致,其中As、Sb、Pb和Zn等元素主异常位于金矿化蚀变带的上盘;Mo和Bi等元素主异常位于金矿化蚀变带的下盘;Au、Ag和W元素主异常与金矿化蚀变带出露位置相吻合。

Abstract:

Yongxin gold deposit is a newly discovered epithermal deposit in the periphery of Duobaoshan area of Heilongjiang Province in recent years,and the scale of the deposit is close to large scale at present.In the process of discovery and evaluation of the deposit,soil geochemical survey has played an important role.The study results show that there are obvious soil geochemical anomalies in this deposit.The anomalous element combinations of 1/50 000 soil are mainly Au,Ag,Bi and Au anomaly area reaches 1.5 km2.1/10 000 soil abnormal zoning phenomenon is obvious,the elements combination is Au,Ag,As,Sb,Bi,Cu,Pb,Zn,Mo and W,of which the maximum value of Au element is 191.9×10-9 and the average value is 26.3×10-9.In the gold mineralization alteration zone,the occurrence site,distribution direction and scale occurrence are consistent with the anomalous features of each element.The main anomalies of As,Sb,Pb and Zn elements are located on the upper plate of the gold mineralization alteration zone.The main anomaly of Mo and Bi elements are located in the lower plate of the gold mineralization alteration zone.The main anomalies of Au,Ag and W elements are highly consistent with the exposed locations of gold mineralized alteration zones.

Key words: soil geochemical survey, anomalous zoning, gold mineralization alteration zone, epithermal gold deposit, prospecting effect, peripheral area of Duobaoshan, Yongxin gold deposit, Heilongjiang Province
