新疆伽师县琼嘎克伯什套铜矿床地质特征及找矿前景

Geological Characteristics and Prospecting of Joan Gakbostao Copper Deposit in Jiashi County, Xinjiang Province

琼嘎克伯什套铜矿床位于塔里木-华北板块、塔里木微板块、柯坪前陆盆地内。已圈定南、北两个矿带,其中北矿带铜矿体呈层状顺层赋存于古近系浅灰-浅灰白色长石石英杂砂岩中,南矿带铜矿体呈似层状、板状赋存于石炭系白云岩中。琼嘎克伯什套铜矿床为有构造热液叠加改造的砂岩型铜矿床。古近系地层和石炭系地层是未来找矿勘查有可能取得新突破的重要地段,矿区进一步扩大矿体规模的前景较好。

Joan Gakbostao copper deposit locates on the Keping foreland basin of Tarim plate of Tarim-North China plate. Till now,we divide it into two ore belts. The copper ore body of north ore belt is layered bedding in the Paleogene gray and grayish white feldspar quartz miscellaneous. The south ore belt bodies are stratoid and plate-like in the Carboniferous dolomite. Joan Gakbostao copper deposit is sandstone type copper deposit with hydrothermal superimposed. The Paleogene formation and the Carboniferous strata is an important area of future ore prospecting. They are likely to achieve new breakthroughs. To further expand,the scale of ore bodies have good prospect.
