相山矿田居隆庵地区铀成矿条件及资源潜力

居隆庵地区位于我国最大的火山岩型铀矿田——相山铀矿田西部,处在东西向基底断陷带、周边被4条断裂构造所圈闭的菱形断块中。铀矿化受构造、蚀变、岩层组间界面及其界面变异部位控制。断裂构造与岩层组间界面及基底界面复合的"三面交汇"部位是成矿的有利部位。现有的矿化信息显示,其垂幅近千米。各矿带和矿床的发展趋势分析表明,以往矿床勘查的深度不够,留下很大的找矿空间。采用不同方法对该区铀资源量进行预测也表明本区铀资源潜力巨大。综合研究认为,深部岩层组间界面与断裂构造交汇区,以及沿矿体走向、倾向追寻新矿体是今后的主攻方向。

Uranium formation conditions and perspective potential of Julong'an area,Xiangshan uranium orefield

Julong＇an area is located in the west of Xiangshan uranium orefield which is the largest volcanic one in China,it is a diamond shaped block surounded by 4 large faults on the uplift part of a EW strike basement faulted depression.Uranium mineralization in this block is controlled by fracture,alteration,interface of rocks and strata and its variable part.The favorable mineralization site is the superposition of fracture,lithologic face and ＂three surfase intersection ＂.Different methods are applied to analyse the distribution trend of orebody and deposit and evaluate the uranium resource,and great potential has been predicted.Due to the misunderstanding of mineralization depth,exploration in the past did not reach enough depth and large prospecting space was left behind,present mineralization indicates that there is nearly 1000 m elevation aplitude.It was believe that clamp zone between lithologic interface and fault,the trending space of orebody are the favourable target for prospecting new orebody.
