摘要
在西藏念青唐古拉地区区域地质背景的综合研究基础上,通过对区内已知矿床、矿化(点)的分析,应用矿床成矿系列理论,将念青唐古拉成矿带主要矿床、矿化(点)划分为2个成矿系列,即海西中期海底喷流-沉积铜-铅-锌-重晶石-石膏矿床成矿系列、与燕山晚期中酸性侵入岩浆活动有关的钨-钼-铜-铅-锌-银矿床成矿系列。提出了区内矿床的找矿评价标志,并对亚贵拉-龙玛拉断拗、昂张-拉屋断拗、桑巴弧后盆地的找矿前景进行了评价。
On the basis of researching the regional geological background,in combination with the analysis of discovered mineral deposits in the region,the theory of metallogenic series was applied,thus the Region of Neoproterozoic is preliminarily divided into 2 metallogenic series,includingthe variscian middle period Hotwater sedimentary Cu,Pb,Zn,barite,gypsum deposit metallogenic serie and W,Mo,Cu,Pb,Zn,Ag deposit metallogenic series,related to late Yanshan movememt intermediate-acid and acid granite.The Regional prospecting criteria was discussed,the prospecting potential of Yaguila-Longmala,Angzhang-Lawufaulted depressed and the Sangba back-arc basin was evaluated and analyzed.
