【摘要】 新疆西天山的群吉萨依中基性侵入-次火山杂岩体,形成于晚古生代晚期后碰撞造山的裂谷构造环境。群吉萨依铜矿体主要赋存于该中基性侵入-次火山杂岩体中。其中,号铜矿体产于隐爆角砾岩筒中,这个发现为该区铜矿找矿提供了新的找矿线索,可将隐爆角砾岩筒型铜矿床作为铜矿找矿的主攻类型。由于隐爆角砾岩筒是直接控制铜矿化蚀变作用的火山机构,因此,群吉萨依铜矿点具有形成大型隐爆角砾岩筒型铜矿床的找矿前景。更多还原

【Abstract】 <Abstrcat>The Qunjisayi intermediate-basic intruded　subvolcanic complex is located in the Awulale Mountain of the western Tianshan, Xinjiang, and was formed in　the rift structure environment after the collision orogenesis of the Late Palaeozoic Era. The Qunjisayi copper deposit occurred mainly in the intermediate basic intruded-subvolcanic complex, For example, the copper body NoⅡlay in the cryptoexplosion breccia pipe This discovery supplied the new exploring key for exploring copper deposit in the area. The cryptoexplosion breccia pipe type of copper deposit may be a most important copper deposit type for exploring copper deposit in the area. The cryptoexplosion breccia pipe of the complex was the volcanic apparatus, which directly controlled the mineralization and alteration of the copper deposit, so there was an exploring foreground for large scale copper deposit controlled by the cryptoexplosion breccia pipe in this district.更多还原
