新疆萨热克铜矿床矿石组构特征与成因
发布时间：2019-03-30 20:05
【摘要】：萨热克铜矿位于新疆乌恰县境内,是我国目前最大规模的砂砾岩容矿的层状铜矿床,主要赋矿地层为上侏罗统库孜贡苏组(J3k)的砾岩及砂砾岩,具有"辉铜矿-斑铜矿-黄铜矿-黄铁矿"的矿化分带,发育完整的杂色地层组合,与典型砂岩铜矿特征相似。通过系统的野外和镜下观察,总结了该矿床矿石的组构特征,结合矿物组合、结构构造、交插关系等特征,将该矿床划分为3个成矿期次,分别为沉积成矿期、热液改造期及表生富集期,初步认为该矿床为与盆地卤水活动有关的低温热液矿床。
[Abstract]:The Sarek copper deposit, located in Wuqia County, Xinjiang, is the largest bedded copper deposit in China at present. The main ore-bearing strata are the conglomerate and gravel of the Upper Jurassic Kuzigongsu formation (J3k), and the main ore-bearing strata are the gravels and gravel rocks of the Upper Jurassic Kuzigongsu formation (J3k). There is a mineralized zonation of "chalcopyrite-porphyry-pyrite", and a complete mottled stratigraphic assemblage is developed, which is similar to that of typical sandstone copper deposits. Based on systematic field and microscopic observations, the ore fabric characteristics of the deposit are summarized. Combined with the characteristics of mineral assemblage, structural structure and interlacing relationship, the deposit is divided into three metallogenic periods, namely sedimentary metallogenic period. The hydrothermal alteration period and supergene enrichment period indicate that the deposit is a low temperature hydrothermal deposit related to brine activity in the basin.
