中文摘要:高昔铀矿床自开采以来,通过阶段性生产探矿和补充地质勘探后,根据探矿资料和采场地质资料的综合分析,对铀矿床成矿特征、矿化特点、矿体形态等方面得到了进一步地了解及论证。通过对矿床287m中段勘探和247m中段深部岩芯钻探探矿后,对矿体的分布和矿体形态的变化特征,具有较全面的认识。事实证明高昔铀矿床矿体形态较为复杂,绝大多数矿体基本上属于陡倾斜团块状、透镜状、不规则状(或者炉渣状)等特征,分布于区域QF2石英断裂构造带上盘燕山期中粗粒斑状或似斑状黑云母花岗岩内,主要富集在F5和F6矿床构造带之间。

Understanding of metallogenic characteristics from the uranium deposits of Gaoxi
Abstract:Since the uranium deposits of Gaoxi from mining,Production of prospecting and supplement through phased after geological exploration,according to the geological prospecting material and the comprehensive analysis of the data mining,Metallogenic characteristics,to the characteristic of mineralization,the form of orebody etc have been further understanding of and demonstration。Through the middle of the middle 247m,287m exploration and deep core drilling prospecting,with a comprehensive understanding for the distribution of the ore bodies and ore body shape variation features,.Facts prove gaoxi deposit orebody form is more complicated,Most orebody basically a steep sloping crumb,lenticular shapes and irregular shape(or slag form) features,Distributed in regional QF2 quartz fracture take dish yanshan midterm coarse grained erythema shape or like black mica in granite erythema shape,Main enrichment F6 deposits in the F5 and between tectonic belt.
