摘要
新疆西准噶尔金矿属岩浆期后热液石英脉型金矿。从有利于找矿角度出发,根据含金石英脉所产出的条件不同,可划分为六种类型。其中以产于玄武岩中及产于中酸性侵入岩接触带附近的含金石英脉意义较大。中酸性侵入岩接触带附近及断裂破碎带是成矿最有利部位,因此是今后找矿的主要地段。而已知矿床的深部及其外围找矿的潜力极大,重要矿带上发现新矿床、寻找新类型的可能性也是极大的。
The west Zhungeer Au-deposit zone is located in north flank of Zhaire-Dalabute synclinorium. It belongs to Hercynian fold zone. The stratum is carboniferous system (C2-3) and the structure system is in east-west direction. The main intrusive rocks are Hercynian.The main types of Au-deposits are: Au bearing quartz vein in basalt; Au bearing quartz in talc-magnelitl rock; Au bearing quartz vein in tuff; Au bearing quartz vein in Fe-bearing jasper rock; Au bearing quartz vean in contact zone of middle-acid intrusive rock; Au bearing quartz vein with slender network in basalt.In looking for gold deposits, attention should be given to periphery area of known deposits; discoveringTnew deposit in the known deposits zone; finding new type of deposit.
