通过对界河金矿控矿断裂的产状变化及其活动方式与金矿体赋存位置关系的研究,揭示控矿断裂在主成矿期表现为左旋正断活动的动力学特征,金矿体赋存的有利部位为断裂构造走向上偏北、倾向上倾角变陡的局部引张扩容部位.矿体向SW侧伏,侧伏角为40°～70°,且总体上保持似等距分布.结合区域含矿下限的分析和矿体空间产状模式,推断Ⅳ和Ⅶ号矿体沿SW侧伏方向向下可能出现第二矿化富集带.

Based on the analysis on the relationship between the spatial location of gold ore bodies and the atti-tude and acting pattern of ore-controlling fracture zones in Jiehe gold deposit, it.was revealed that the ore-controlling fractures were characterized by sinistral normal acting pattern during mineralization, the favorable locations for ore bodies were partial extensional positions among faults, where stroked northwards and dipped deeply. The ore bodies were commonly SW side dipping with the angle of 40°～70° and distributed near-equidistance. Finally, combined with studies on the limit of regional ore-bearing depth and the ore body spatial location model, it was predicted that a second mineralization enrichment zone might exist beneath Ⅳ and Ⅶ ore bodies along SW side dipping direction.
