辽宁五龙金矿为大型石英脉型矿床,主要是断裂构造控矿;其矿体主要赋存于近SN、NW向断裂组成的格子状构造中。随着开采量的增加,该矿步入危机矿山行列,如何解决五龙金矿找矿问题,已迫在眉睫。本文结合两个方向构造所控制的矿体实例,论述辽宁五龙金矿近SN向与NW向控矿构造的特征及其对成矿的控制作用;总结出近SN向构造控矿规律是平面上尖灭侧现、剖面上向SSW侧伏,NW向构造控矿规律是平面上尖灭再现、剖面上向SE侧伏。在此基础上指出五龙金矿进一步找矿方向。

Wulong gold deposit is a large-sized quartz-vein-type deposit in Liaoning Province,the ore-body distribution of which is mainly controlled by lattice structures consist of nearly SN and NW trending faults.The deposit,however,begins to become exhausted along with further mining,which urgently need to be solved for the future ore prospecting.This paper analyzes the characteristic of two mineral ores controlled by the nearly SN and NW trending structures in order to study the two oriented structures and their influences on mineralization.It is concluded that ore bodies appear in nearly SN trending fault as an echelon in three-dimension and plunge to the SSW direction in the cross section,and also occur discontinuous in NW trending fault and plunge to the SE direction in cross section.
