| 摘 要： | 黑龙江省呼玛县西部兴隆-基座山地区为瓦拉里-兴隆金矿带中重要的金矿化集中区。区内水系沉积物测量主要组合异常区地质特征与呼玛矿集区已知浅成低温热液金矿床地质特征具有可比性,在岩性条件、构造环境、矿化蚀变等方面和矿集区矿床地质特征相一致。区内水系沉积物及土壤测量均发现存在Au、Ag、As、Sb、Bi、Cu组合异常,异常分带清晰,具有明显的浓集中心。水系沉积物主要异常元素组合与矿集区已知浅成低温热液金（银）矿床周围异常元素组合相一致,金异常及其伴生元素异常均受次级断裂构造、岩体与地层接触带及破碎带控制。依照类比结果,区内划分了3个异常远景区,对部分远景区进行工程揭露,发现蚀变矿化带金含量明显增高,局部可见金矿化体,表明区内寻找浅成低温热液型金矿床具有广阔前景。

| Abstract: | Xinglong-Jizuoshan area in western Huma county,Heilongjiang province is an important gold mineralization accumulated area in Walali-Xinglong gold ore belt.The geological characteristics of major assembled anomaly area of stream sediment measurement in the area is comparable with that of epithermal gold deposit and in line with that of ore accumulation area from the view of lithological condition,structure environment and mineralization and alteration.Both stream sediment and soil measurement in the area have recognized the occurrence of assembled anomaly of Au,Ag,As,Sb,Bi and Cu with apparent anomaly zoning and clear concentration center.The key element assemblage of the anomaly is consistent with element assemblage of the anomaly in known epithermal gold（silver）deposit,and gold anomaly and its associated element anomaly all controlled by secondary fracture and contact zone of magmatic rock with stratum or crush zone.Three promising areas were recognized in the anomaly area based on analogizing result and a few testing projects were carried out in part of the promising areas,resulting in the discovery of alteration-mineralization zone with increased gold content and gold mineralization bodies seen in part,which shows that there is a strong potential for epithermal gold deposit prospecting in the area. |
