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。
Based on the comprehensive analysis of the metallogenic conditions of uranium in Mingyuefeng area, the author thinks that the uranium metallogenic prospect in this area is in the granite and not in the belt. The granitic uranium mineralization belongs to the fragmentary alteration granite (soluble leaching). It is concluded that the tectonic setting, rock alteration and elemental assemblage are favorable for uranium metallogenesis in this area. Northern granite is the fissile alteration granite-type uranium mineralization prospect. The favorable metallogenic belt is F1. F3 and F43 fractured tectonic mineralization zones. It is pointed out that in the future, the focus of uranium mine survey and exploration in this area should be shifted from the outer zone to the prospecting and economic evaluation of fractured alteration granite-type uranium deposits.
