Abstract Most of the gold deposits in the Xongershan area,Henan province,occurr in NE-and E W-trending faults.But the recently discovered Xiaonangou deposit is in the fault running north-south,which appears to show a new approach for exploring in this district.The study on the fault system around the mine suggests that the S-N-trending fault controlling the orebodies is composed by the conjugate NE-and NNW-trending. Based on that,it is considered that the intersections of the faults running NNW,NE,and NWW,especially the fault along NE,are good ore-forming positions for gold deposits.The orebody sidepitches rapidly to north,which may be coursed by the pitching to north of the E-W fault or the cross line of the faults trending NE and NNW.
