【摘要】 本文依据近年西藏自治区矿产资源大调查的资料与西藏自治区矿产资源潜力评价研究获得的系统、详细的矿产资源资料,系统总结了西藏自治区金属矿床成矿系列及矿床成矿谱系,重点论述了喀喇昆仑(羌塘)-三江成矿省(含西金乌兰-金沙江成矿带、北羌塘-昌都成矿带及喀喇昆仑-他念他翁成矿带)的矿产地质特征及成矿分布规律与成矿系列。羌塘-三江成矿区除喀喇昆仑-他念他翁成矿带(Ⅲ-37)的多龙、美多及当曲等矿床分布在南羌塘与他念他翁地区外,其他主要矿床都分布在藏东三江地区。羌南地区主要有与燕山中晚期岩浆作用有关(如多龙铜矿)矿床成矿系列、与新生代流体-改造有关(如美多锑矿)矿床成矿系列和与燕山中晚期层控热液-改造有关(如当曲铁矿)矿床成矿系列。喜马拉雅期在藏东三江地区的成矿事件是非常重要的金属矿床成矿事件。造山带产生大规模走滑-伸展、推覆-剪切及其伴生的富钾碱性斑岩(岩浆热液)、弧后前陆盆地两侧推覆形成的盆地流体系统(以热液对流系统为特征),构成了玉龙铜矿为代表的Cu-Mo-Ag成矿系列和拉诺玛铅矿为代表的Pb-Zn-Sb成矿系列,及美多锑矿为代表的Sb-Ag成矿系列。更多还原

【Abstract】 Information based on extensive investigation of mineral resources in recent years,the Tibet autonomous region and the Tibet autonomous regional mineral resources potential evaluation research on the system,detailed mineral resources information,the system summary writing Tibet metal metallogenic series of ore deposits and metallogenic spectrum(four papers).This paper discusses the Karakoram(qiangtang)-jinshanjiang metallogenic provinces(including Xijingulam-jinshajiang metallogenic belt,North qiangtang-changdu metallogenic belt and the Karakoram-tanietaweng metallogenic belt)of mineral geological characteristics and distribution regularity of mineralization and metallogenic series.Qiangtangjiangshajiang metallogenic province in addition to the Karakoram-tanietaweng metallogenic belt(Ⅲ-37)DuolonCu,MeiduoSb and Danqu Fe deposits when the song deposit distribution in southern Qiangtang and Tanietaweng region,other major ore deposits are distributed in Cangdu jinshanjiang area.Qiang south region are mainly related to middle-late yanshan movement in the magmatism,such as more DuolonCu deposit metallogenic series,related to Cenozoic fluid-transformation,such as MeiduoSb deposit metallogenic series and related to yanshan period stratabound hydrothermal-transformation,such as DanquFe deposits when the song deposit metallogenic series.Himalayan period in Cangdu-jinshajiang region mineralization is one of the most important metal deposit metallogenic events.Orogenic belt have large-scale strike-slip stretching,nappe shear and its associated rich potassium alkaline porphyry(magmatic hydrothermal),arc first on both sides of the foreland basin formed nappe basin fluid system(characterized by hydrothermal convection system),constitutes the YulongCu deposit represented by CuMoAg metallogenic series and the Norma Pb deposit represented PbZnSb metallogenic series of ore deposits,and MeiduoSb deposit as representative′s SbAg metallogenic series of ore deposits.更多还原
