| 摘 要： | 本文通过对明月峰地区铀成矿条件的综合分析，认为该区铀成矿远景区在花岗岩内带，而非外带；花岗岩铀矿化类型属碎裂蚀变花岗岩型（可溶浸）；总结出该地区有利于铀成矿的构造环境、岩石蚀变组合及元素组合特征；提出北部花岗岩为碎裂蚀变花岗岩型铀矿成矿远景区，有利成矿带为F1．F3，F43条断裂构造矿化带；指出今后该区铀矿普查勘探重点应（从外带）转向内带碎裂蚀变花岗岩型铀矿找矿及经济评价上。

| Abstract: | By comprehensive analysis of uranium mineralization, this paper proposes that the uranium mineralization prospect in Mingyuefeng area is in the endocontact of granite, ratherthan in the exocontact of granitic massif and the uranium mineralization is of leachable cataclastic alteration granite type. This paper also summarizes the favorable structural settingand association characteristics of wall-rock alteration and elements association of uraniummineralization, and suggests that the northern granite has the prospect for cataclastic-alteration granite-type U-mineralization and the favorable metallogenic zones are F1,F3 and F4fault structures and that the future work of uranium reconnaissance survey and prospectingshould be emphasized on the prospecting and econonmic evaluation on the cataclastic-alteration granite--type uranium deposits in the endocontact zone of granitic massif instead of theexocontact zone. |
