黑龙江十四工段地区金多金属矿找矿前景分析

十四工段地区金多金属矿处于张广才岭—太平岭边缘隆起带中部。区内火山—岩浆活动频繁,构造发育,具备良好的成矿地质条件。在该区通过开展1/5万水系沉积物测量工作,圈出水系沉积物单元素异常205处,水系沉积物组合异常26处,其中Hs-18号组合异常位于研究区内。为在十四工段地区寻找以金为主的多金属矿产,对Hs-18号组合异常进行了查证,采用1/2万土壤测量、1/2万地质简测、1/2万高精度磁法测量、激电中梯测量及槽探等方法,在区内圈定出土壤单元素异常89处,组合异常8处,发现低品位金矿体1条、金矿化体1条,表明该区具有较好的找矿前景。

Ore Prospecting Prospect Analysis of the Gold Polymetallic Deposit at Fourteen Section Region in Heilongjiang Province

The gold polymetallic deposit at fourteen section region located at middle part of the Zhangguangcailing-Taipingling edge uplift belt.It was found that the volcano-magmatic activity was frequent in the area,together with structure development and good ore-forming geological conditions.Through 1/50 000 stream sediment survey work in the study area,approximately 205 ingle element anomalies of stream sediments were identified,additionally,26 combination anomalies of stream sediments were also defined and these include the Hs-18 combination anomalies. In order to search for gold dominated polymetallic ore at the fourteen section area,verification work was carried out at the Hs-18 combination anomalies.The methods applied in this study including 1/20 000 soil measurement,1/20 000 geological detection,1/2 000 high-precision magnetic measurement,IP ladder measurement and methods of trenching.Finally,we defined 89 single element anomalies for soil,8 combination anomalies,one low grade gold ore body,one gold mineralization body, which suggested that the area has good ore prospects.
