| 摘 要： | 中酸性浅成岩金，铜矿床是新疆东准噶尔地区一个重要的新成矿系列，通过总结有关中酸性小岩体及其典型矿床的基本特征，将该成矿系列划分为浅成岩－构造蚀变岩型金矿，类夕卡岩型铜钼矿，细脉浸染型（斑岩型）铜，金矿及隐爆角砾岩型脉状铜矿等基本矿化类型，并探讨了有关典型矿床的REE特征，建立了该成矿系列的总体成矿模式，认为该成矿系列受控于海西中晚期的中酸性浅成小杂岩体，其岩石化学成分，REE特征及成矿作用方式具有明显的相似性。

| Abstract: | Gold and copper deposits related to intermediate acid hypabassal rocks are an important new metallogenetic series in Easten Juggar area of Xinjiang. By summarizing their basic features of the correlated little intermediate acid complexes and typical ore deposits, the authors divided this metallogenetic series into 4 basic mineralizing types: hypabassal and altered tectonite type gold deposits,skarnoid type copper molybdenum deposit, veinlet disseminated type copper gold ore deposits(porphyrite type deposits) and cryptoexplosion breccia type copper bearing veins. Meanwhile, the authors yet discuss their REE geochemical characters of some typical deposits and establish the general mineralizing model of this metallogenetic series. At last, it is thought that the metallogenetic series are regularly controlled by a series of little intermediate acid hypabassal complexes formed in middle late Hercynian period, and the petrochemical compositions, REE characters and correlative mineralizing patterns are obviouly similar. |
