粤北佛冈岩体琶江地区断裂构造特征与找矿方向OACSTPCD
Fault Characteristics and Uranium Prospecting Direction in Pajiang Area of Fogang Pluton in Northern Guangdong
粤北佛冈复式岩体中部琶江地区断裂构造发育,主要有近东西向、北东向、北西向、北北西向及近南北向五组.文章对这五组断裂构造进行了野外调查及室内综合研究分析,将区内断裂构造划分为三级,一级断裂为近东西向社岗-门楼富断裂、竹园-草子顶断裂;二级断裂为北东向仙人石断裂、汤塘断裂;三级断裂为北东向次级断裂、北西向、北北西向及近南北向断裂.其中近东西向、北东向断裂为压扭性断裂,控制了区内铀矿床、铀矿点的分布与产出,为重要的控岩控矿断裂;北北西向17号带、近南北向5号、83号带、F1-1断裂带为主要含矿构造,次级北东向2号带、F1 断裂带为次要含矿断裂.综合分析认为区内北北西向17号带、近南北向5号、83号带、F1-1断裂带为下一步重点工程揭露部位.
The fault structure in Pajiang area of the central Fogang complex pluton in northern Guangdong province is mainly divided into five groups:nearly east-west,northeast,north west,north northeast,north north west and nearly south-north.The paper conducted field survey and indoor comprehensive analysis of the five groups of fault structures,and divided the fault structure in the area into three levels:the first level faults are nearly east-west Shegang-Menloufu fault and Zhuyuan-Caoziding fault;the second level faults are northeast Xianrenshi fault and Tangtang fault;the third level faults are northeast,northewest,north north west and nearly south-north.Among them,the nearly east-west and northeast faults are compression-torsion faults,which control the distribution and output of uranium deposits and occurrences in the area,and are important rock-control and ore-control faults;the north north-west No.17 fault,nearly south-north No.5,No.83 and F1-1 faults are tensile-torsion faults,which are the main ore-bearing structures,and the secondary north east No.2,F1 faults is a minor ore-bearing fault.The comprehensive analysis shows that the north north-west No.17 fault and nearly south-north No.5,No.83 and F1-1 faults in the area are the key expose target of the next project.
