齐Ⅲ金矿位于西准噶尔安齐断裂上盘,与西部哈图、齐Ⅱ金矿及东部齐IV、宝贝、灰绿山金矿构成哈图成矿带。赋矿凝灰岩、凝灰质泥岩及凝灰质粉砂岩发育白云母化、硅化、碳酸盐化和黄铁矿化蚀变。成岩成矿过程可分为草莓状黄铁矿阶段(I)、白云母-石英阶段(Ⅱ)、孤立黄铁矿阶段(Ⅲ)、硫化物-自然金阶段(Ⅳ)、方解石-黄铁矿阶段(V)、铁白云石-钠长石阶段(Ⅵ)和石英-方解石阶段(Ⅶ)。含砷黄铁矿的As与S含量呈负相关,晚期黄铁矿几乎不含砷。稀土元素模式为右倾,Cs,Rb,La,Ce,Ti,V,Cu,Zn在强蚀变凝灰岩中亏损,说明它们被热液从围岩中萃取迁移带出,Cr,Ni,Mo被流体带入围岩。硫化物-自然金阶段(IV)形成温度为301℃~340℃,硫逸度logf(S2)为-8.1~-10.8,其值高于哈图金矿低于东部宝贝金矿,暗示由西向东成矿深度逐渐变深。
Qi Ⅲ gold deposit is located in the upper Anzai fault of West Junggar, and forms a Hatuang metallogenic belt with the western Hatu, Qi Ⅱ gold deposit and the eastern Qi, Bao, and Huangshanshan gold deposits. Mineralized tuffs, tuffaceous mudstones and tuffaceous siltstones develop muscovite, silicification, carbonatation and pyrite alteration. Diagenesis and mineralization process can be divided into strawberry pyrite stage (I), muscovite quartz stage (Ⅱ), isolated pyrite stage (Ⅲ), sulfide-natural gold stage (Ⅳ), calcite-pyrite Stage (V), iron dolomite-albite stage (VI) and quartz-calcite stage (VII). As and S contents of arsenic-bearing pyrite are negatively correlated, and late pyrite contains almost no arsenic. Rare earth element patterns are rightward and Cs, Rb, La, Ce, Ti, V, Cu, Zn are depleted in strongly altered tuffs, indicating that they are extracted by migration from the surrounding rock and Cr, Ni, Brought into the rock. The formation temperature of sulfide-natural gold stage (IV) is 301 ℃ ~ 340 ℃, and the sulfurflux logf (S2) is -8.1 ~ -10.8, which is higher than that of Hatu gold deposit, East mineralization depth becomes deeper.
