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.
