东准噶尔地区存在与两类花岗岩有关的两个金属成矿系列:与钙碱性花岗岩类有关的铜、金成矿系列和与富碱花岗岩类有关的锡成矿系列。钙碱性花岗岩成因上属造山后陆内断裂深熔型,富碱花岗岩属A型或S型。前者主要形成于华力西中晚期、华力西晚期;后者也主要形成于华力西中晚期、华力西晚期,岩石以富含碱性暗色矿物为特征。与钙碱性花岗岩有关的铜、金成矿系列矿床类型有斑岩型、隐爆角砾岩筒型、夕卡岩型、破碎带碎裂岩型和石英脉型,与富碱花岗岩有关的锡成矿系列矿床类型有锡石-石英脉型、蚀变花岗岩型和富石英云英岩型。斑岩型、隐爆角砾岩筒型铜(金)矿及与A型花岗岩有关的锡矿等新矿床型的存在,为该区钢、金、锡等矿产资源的进一步探寻.提供了重要方向。该区存在十分有利的构造、岩浆成矿条件、广泛发育的蚀变矿化现象和多种多样的矿化类型,地质研究程度和找矿工作程度低.表明该区具有广阔的找矿前景。
There are two metallogenic series related to two types of granites in East Junggar: copper and gold metallogenic series related to calc-alkaline granitoids and tin metallogenetic series related to alkali-rich granitoids. The genesis of calc-alkaline granitoids belongs to the intra-continental intracontinental fault deep-melting type and the alkali-rich granites belong to A type or S type. The former is mainly formed in the middle and late stage of the Valsalva, the late stage of the Variscan. The latter is also mainly formed in the middle and late stage of the Variscan. In the late stage of the Variscan, the rock is characterized by its rich alkaline brown minerals. The types of copper and gold mineralization series associated with calc-alkaline granites include porphyry type, cryptoexplosive breccia type, skarn type, fractured rock type and quartz vein type, tin-rich granite-related tin The metallogenic series of deposit types are cassiterite-quartz vein type, altered granite type and quartz-rich quartzite type. The presence of new deposit types such as porphyry type, cryptoexplosive breccia tubular copper (gold) deposit and tin ore related to A-type granite are further exploration for the mineral resources of steel, gold and tin in the area. Provide an important direction. The area has very favorable tectonics, magmatic mineralization conditions, extensively developed alteration mineralization and a wide variety of mineralization types, with a low degree of geological research and prospecting. Indicating that the area has a broad prospects for prospecting.
