红海铜锌矿床位于东天山大南湖—头苏泉岛弧带北段的卡拉塔格地区。矿体产于英安质熔岩下盘的凝灰岩内,矿体上部以闪锌矿、黄铜矿、黄铁矿为主,呈块状分布在英安质熔岩与凝灰岩界面附近;下部为黄铜矿、黄铁矿,呈浸染状、网脉状分布在凝灰岩内;矿区普遍发育硅化、绢云母化、绿泥石化、碳酸盐化等低温蚀变组合。红海铜锌矿床主要受到近东西向断裂、北西-北北西向断裂与北北东向断裂的控制,三者均有破矿作用,其中北北向断裂还具有导矿和控矿作用。可识别红海铜锌矿至少经历了2期成矿作用,早期为火山机构控制,形成了VMS型块状铜锌矿体;之后受北北西向断裂控制,形成网脉状的低温热液型铜矿,并叠加在了早期块状铜锌矿体下盘。
The Red Sea copper-zinc deposit is located in the Calataghu region of the northern segment of the arc zone of Dalang Lake - Tousuquan Island in the East Tianshan Mountains. The ore body is produced in the tuff of the lower plate of the British amphibolite. The upper part of the ore body is dominated by sphalerite, chalcopyrite and pyrite. The ore body is distributed in the vicinity of the interface between the quartz-hosted lava and tuff. The lower part is brass Mine, pyrite, was disseminated, mesh veins distributed in the tuff; mining generally developed silicification, sericitization, chloritization, carbonate and other low temperature alteration combinations. The Red Sea Cu-Zn deposit is mainly controlled by near-EW faults, NW-NNW faults and NE-trending faults, all of which have ore-bearing faults. North-north trending fractures also have ore-bearing and ore-controlling effects. The Red Sea copper and zinc mine can be identified at least two stages of mineralization, volcano body control early to form a VMS-type bulk copper-zinc ore body; followed by north-northwest fault control, the formation of reticular hypothermia hydrothermal copper Ore, and superimposed on the early bulk copper-zinc ore body under the plate.
