【摘要】 东堆—同富地区位于我国最大的火山岩型铀矿—相山矿田西部。本文在前人勘查和研究工作的基础上分析了工作区地质特征、铀成矿地质条件、铀矿化特征和铀资源潜力,并重点对成矿有利地区的地质、物探、化探特征进行了研究、针对地表铀矿化（异常）及重要的物化探异常进行了槽探查证、追索。综合分析认为:北东向王龙—土塘构造（F₁）为本地区主要导矿构造,北西向低级别低序次断裂裂隙为主要控矿、贮矿构造、地面伽马能谱及土壤²¹⁰Po测量成果显示沿控矿断裂走向和倾向方向发育有串珠状的铀和钋异常晕,表明本地区具有良好的浅、深部铀矿化信息;音频大地电磁测深测量成果也显示,本地区控矿构造和火山熔岩向下均有100～500 m的延伸,局部可达700 m,东堆—同富地区具有较优越的成矿地质条件,具有较好的寻找火山熔岩型铀矿化的找矿潜力,值得进一步开展地质找矿工作。更多还原

【Abstract】 Dongdui-Tongfu Section is located in the west party of Xiangshan ore-field which is the largest volcanic type uranium ore-field in China.Base on previous surveys and research work on the basis of the analysis of the geological features of the workspace,uranium ore-forming eological conditions and characteristics and uranium resources potential of uranium mineralization,And the metallogenetic prospective area,geophysical and geochemical characteristics of the research,Surface uranium mineralization or unusual and important channel exploration permits,the geophysical and geochemical anomalies of recourse.Comprehensive analysis shows that the Northeastwardly Wanglong-Tutang Structure（Fl） is the ore-passing structure,and the lower-level,lower-oder Northwest wardly fractures are the main ore-controlling and ore-storage structures.The terrestrial gamma spectroscopy and soil ²¹⁰Po measurement results show that,there are beaded uranium and polonium abnormal halos in the Northwestwardly fractures indicating that,the section has good shallow,deep uranium mineralization informations;Audio magnetetotelluric sounding measurement results also show that the ore-controlling Structure and the magmatic rocks of the section extend down for about 100～500 m,local up 700 m.The Dongdui-Tongfu Section has superior metallogenic conditions and has a better looking for volcanic-type uranium mineralization and ore potential.Further geological prospecting work carried out.更多还原
