| 摘 要： | 阿依托汉矿区位于阿尔泰山区南缘的阿舍勒Cu-Au-Pb-Zn矿带,共发现5条铜矿体,铜矿体主要赋存于下-中泥盆统阿舍勒组第一岩性段的大理岩和变质凝灰岩中,少量产于石英斑岩脉中;与成矿有关的中泥盆世英云闪长岩和晚期岩脉提供了成矿热源并形成与矿化相关的矽卡岩化、硅化、绢云母化、绿帘石化等围岩蚀变;玛尔卡库里大断裂的次级断裂(F5韧脆性断裂)控制了铜矿体的储矿空间;成矿主要经过了早-中泥盆世(火山-沉积作用)、中泥盆世(岩浆侵入作用)和中-晚泥盆世(铜矿的主矿化阶段)多个阶段,是多种地质因素的耦合导致最终成矿。矿床体现了"层控-岩控-构控-时控"四位一体控矿的特点,不宜用单一的成矿模型予以描述定位,矿床类型属于热液交代-充填型铜矿床。文章在总结找矿标志的基础上,对下一步的找矿方向进行了探讨。

| Abstract: | The Ayituohan copper deposit is located in the Ashele Cu-Au-Pb-Zn ore belt of the South Altai metallogenic belt at the south margin of the Altai mountains in Xinjiang.Five ore bodies discovered occur mainly in the marble and metamorphic tuff of the first lithologic member of Lower-Middle Devonian Ashele formation,a few in quartz porphyry dyke.The Middle Devonian tonalitic diorite is the heat source and lead to skarnization,silicification,sericitization epidotization etc.Spatially the ore body is controlled by the ductile-brittle sub-faults F5 of Maerkakuli fault.Mineralization is the coupling of multi-geological factors and can be divided into stages of Early-Middle Devonian volcano-sedimentation,Middle Devonian magma intrusion,the main ore-forming stage of Middle Devonian Epoch.The deposit is characterized by combination of satratum-lithology-strcrure-time control and a single model is not proper to describe the location of the ore boidies.It is a thermal metasomatic-filling copper deposit.This paper summarizes the prospecting marks and makes discussion on the prospecting directions. |
