摘要
在系统收集、整理修水桂坳区地质、矿产、物化探、遥感、前期铀矿勘查成果资料及相关文献报告基础上,运用地面伽马能谱测量方法,对该地区进行放射性异常测量,总结了该地区的放射性异常分布特征及其与岩性、断裂构造的潜在关系。修水桂坳地区处于区域铀成矿构造带内,经历了多期次的构造运动,断裂构造、层间破碎带、节理、裂隙带发育。铀异常主要分布在王音铺组、观音堂组地层中,沿深大断裂走向延伸,在断裂附近的断裂裂隙密集区分布更为显著。通过对异常分布特征的分析,确定了修水桂坳地区放射性异常分布受岩性、深大断裂、层间破碎带以及断层裂隙共同影响。
On the basis of systematically collecting and sorting out preliminary information on uranium exploration results and related literature report on geology,mineral resources,geophysical and geochemical exploration and remote sensing in Guiao area of Xiushui County,using ground gamma spectrometry,we measured radioactive anomalies in this area,the distribution characteristics of radioactive anomalies and their potential relationship with lithology and fault structures are summarized.Guiao area is located in the regional uranium metallogenic tectonic belt,has undergone many stages of tectonic movement,fracture structure,interlayer fracture zone,joint and fracture zone are developed.The uranium anomalies are mainly distributed in the stratum of Wangyinpu and Guanyintang formation,extending along the deep fault and distributes more significantly in the fractured fissure dense area near the fault.By analyzing the distribution characteristics of anomalies,it is determined that the distribution of radioactive anomalies is influenced by lithology,deep faults,interlayer fracture zones and fault fractures in Guiao area of Xiushui County.
