摘要
枪口南银多金属矿位于东昆仑多金属成矿带东段,1:2.5万沟系沉积物测量在矿区圈定出以Ag、Cu、Pb、Zn、Mo为主的综合异常4处.经异常查证,圈出9条矿化带,21条矿(化)体,取得了较好的找矿效果.通过进一步异常查证,在AS1、AS2异常中Ⅶ、Ⅷ和Ⅸ号矿带内圈出银、银铅锌以及银金砷异常高值段,展示出了异常区具较好的银多金属矿的找矿远景. AS3异常内的Ⅳ号含矿花岗斑岩体深部发现多条铜多金属矿(化)体,且发育较强的围岩蚀变,显示具有较好的斑岩型铜多金属矿找矿潜力. AS4异常内Ⅰ-Ⅲ号金矿化带具较好的金多金属矿找矿潜力.本区具有优越的成矿地质条件,化探异常发育,且已发现了较好的银多金属矿找矿信息,充分展示出本区具较大的找矿潜力.
The Qiangkounan silver polymetallic orefiled is located in the eastern section of East Kunlun polymetallic metallogenic belt. Four integrated anomalies(AS1-AS4)dominated by Ag,Cu,Pb,Zn and Mo are identified by the 1:25000 scale trench sediment survey. Through anomaly verification,9 mineralized zones and 21 ore(mineralized)bodies are delineated with good prospecting results. The Ag,Ag-Pb-Zn and Ag-Au-As high value areas in Ⅶ,Ⅷ andⅨ ore belts of AS1 and AS2 anomalies are determined by further anomaly verification,which shows a good prospect for Ag-polymetallic deposit in the area. Many Cu-polymetallic ore(mineralized)bodies are found in the deep ore-bearing granite porphyry bodies in AS3 anomaly with strong wall rock alteration,indicating good porphyry Cu-polymetallic deposit prospecting potential,while the Ⅰ-Ⅲ gold mineralized belts in AS4 anomaly have good prospects for Aupolymetallic deposit. From the above,the favorable metallogenic conditions,developed geochemical anomalies and informative clues of Ag-polymetallic ore prospecting fully show that the area has great prospecting potential.
