| 摘 要： | 火山岩型铀矿床均产于古陆壳之上的酸性（或偏碱性）陆相火山岩系中,文章根据中国陆相火山岩系的产出环境,结合铀矿床、矿点及矿化点的分布,划分出6条火山岩型铀矿成矿带和8条火山岩型铀矿远景带（预测工作区）,对铀矿化集中区进一步划分出21个预测区。根据含矿主岩及控矿构造特征,将火山岩型铀矿床分为5个亚类、16个矿床式（29个典型矿床）,建立了成矿模式,并在此基础上划分出4个预测类型,总结了火山岩型铀矿的成矿要素、预测要素及成矿规律。对14个预测工作区和21个预测区编制了系列图件,圈出了预测工作区靶区近200个,并分别采用数量化理论Ⅰ、品位吨位法、体积法及德尔菲法对各预测工作区和预测区500m以浅及1 000m以浅的铀矿资源量进行了估算。编制了火山岩型铀矿勘查工作部署图,对今后铀矿地质工作及铀矿大基地建设提出建议。

| Abstract: | In China,volcanic type uranium deposits occur in the main continental acid or alkaline volcanic.Based on the tectonic environments of host volcanic and the distribution characteristics of uranium deposits and occurrences,6 volcanic type uranium mineralization belts,8 volcanic type uranium mineralization prospective belts and 21 mineralization clusters can be drawn.The volcanic type uranium deposits are classified into 5 sub-types,16 deposit trypes,29 typical deposits and 4 prediction types based on the host rocks and ore-controlling structures.The metallogenic feature,ore-controlling factors and predictive factors of volcanic type uranium deposits have been summarized.Maps of different predicting factor for 21 prediciont areas was compiled to delineate target area.Some 200 target areas was delineated and their resource potential within the depth of 500 m and 1 000 m was evaluated with the mehod of ditalization theory 1,grade-tone,volume and Delphi.The deploy map for volcanic uranium exploration was compiled and the suggestions to enlarge mine base was proposed for the future efforts. |
