新疆库车县盐水沟北铜矿床地质特征及成因探讨

Geological Characteristics and the Origin of Yanshuigoubei Copper Deposit in Kuche County in Xinjiang Uygur Autonomous Region

摘要:

盐水沟北铜矿区位于新疆库车县北部，其大地构造位置处于塔吉克塔里木陆块区、塔里木陆块、塔里木北缘隆起、库车前陆盆地，区内构造活动强烈。铜矿床赋存于新近纪中新统康村组第一岩性段，矿体呈层状，严格受地层控制。区内共圈定10个铜矿体，矿石矿物主要为孔雀石、赤铜矿、水胆矾、自然铜等，矿体内无夹石，顶、底板围岩均为褐红色及浅红色粉质泥岩。该矿床为砂岩型铜矿床。

Abstract:

Yanshuigoubei mine is located in the north of Kuche county in Uygur Autonomous Region. Its tectonic position is in Tajikistan Tarim block area, Tarim block, northern Tarim uplift and Kuche foreland basin. Tectonic activity in this area is strong. The copper deposit occurrs in the first lithologic section of the Neocene Tongkangcun formation. The ore body is stratified and is strictly controlled by the strata. 10 copper ore bodies have been delineated, and ore minerals are malachite, cuprite, brochantite and natural copper with no stone. Roof and floor rock are brownish red and light red silty mudstone. The deposit is a sandstone type copper deposit.
