摘要
根据地质建造和成矿特征,借鉴我国地质学家创立的矿床成矿系列理论,对阿尔泰成矿省的成矿系列进行了深化研究。按照成矿作用与地质建造的时间关系,将成矿系列细化为"同生"、"准同生"、"后生"、"表生风化"等类别,再将同一套地质建造有关的几个世代的成矿系列构成一个成矿系列家族。本次将北阿尔泰成矿带(Ⅲ-1)总结为4个成矿系列家族:加里东期伟晶岩有关RM-白云母-宝石成矿系列家族、华力西期火山-沉积岩系有关Fe-Pb-Zn-Cu-Mo-Au-Ag成矿系列家族、华力西期中酸性伟晶岩有关RM-白云母-宝石成矿系列家族、新生代沉积物有关的Au成矿系列家族;将南阿尔泰成矿带(Ⅲ-2)总结为5个成矿系列家族:加里东期伟晶岩有关RM-白云母-宝石成矿系列家族、华力西期火山-沉积岩系有关Fe-Cu-Pb-Zn-Au-Ag成矿系列家族、华力西期中酸性侵入岩有关Cu成矿系列家族、印支期伟晶岩有关RM-白云母矿床成矿系列家族、新生代陆相沉积物有关Au-RM-石英砂成矿系列家族。该成矿系列家族的建立为阐明区域成矿规律奠定了基础。
According to the geological and metallogenic characteristics of geologists,the metallogenic series are further researched based on the theory which is founded in the Altay metallogenic province.The metallogenic series are divided into the syngenetic,parasyngenetic,epigenetic series,and superficial weathering.Several metallogenic series are related to the same geological formation which comprises a metallogenic series family.In this study,the mainmineral deposits of the North Altay metallogenic zone（Ⅲ-1）and the South（Ⅲ-2）fall into 4and 5series families：the Caledonian period pegmatite is related to the RMmuscovite-gem metallogenic series family,the variscan volcanic sedimentary is related to the Fe-Pb-Zn-CuMo-Au-Ag metallogenic series family,the variscan midterm acidic pegmatite is related to the RM-muscovite-gem metallogenic series family,the Cenozoic sediments are related to the Au metallogenic series family,the Caledonian period pegmatite is related to the RM-muscovite-gem metallogenic series family,the variscan volcanic sedimentary is related to the Fe-Cu-Pb-Zn-Au-Ag metallogenic series family,the variscan midterm acidic intrusive rocks are related to Cu metallogenic series family,the indosinian period pegmatite is related to the RM-muscovite metallogenic series family,the Cenozoic continental deposits are related to the Au-RM-quartz sand of quartz sand metallogenic series family.This research builds the foundation of clarify the regional metallogenic regularity.
