摘要
302铀矿床位于棉花坑断裂与油洞断裂夹持部位,是粤北地区乃至全国最具代表性的花岗岩型铀矿床之一。矿体主要呈脉状、透镜状产出在花岗岩体的内部裂隙带中,在空间和成因上与诸广山复式花岗岩体有着密切的关系。研究表明,该区域经历了不同时代和不同阶段的构造-岩浆活动,这些地质活动对矿床形成的作用明显。本文在总结区域地质背景、构造-岩浆热事件以及矿床地质的基础上,从印支期晚期及燕山期早期的控矿构造和燕山期晚期的破矿构造分析,辅助以矿物学和围岩蚀变的研究,划分成矿阶段,进而加以论述不同构造活动对矿床的改造,为矿床的深部及外围找矿提供技术支撑和信息指导。
302 uranium deposit is located in the cotton fracture and fracture oil hole clamping parts,the pit is the same area and even the whole country one of the most representative of granite type uranium deposit.Main ore bodies are vein,lenticular output in the interior of the granite rock mass fissure zone,in space and origin and the wide compound granite mountains have a close relationship.Research shows that the region has experienced different age and different stages of tectonomagmatic activities,these geological activities on the deposit formation effect is obvious.This article summarizes the regional geological background,tectono-magmatic thermal events and ore deposit geology,on the basis of the late indo-chinese epoch and early yanshan epoch of ore-controlling structure and broken ore structure analysis of late yanshan epoch,aided by mineralogy and wall rock alteration,mineralization stage,divided into rehabilitation of ore deposit and discussed such different tectonic activities,for the deposit of the deep and periphery prospecting guide to provide technical support and information.
