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 study of the occurrence change of the ore-controlling fault in the Jiehe gold deposit and the relationship between its activity mode and the depositing position of the ore body, it is revealed that the ore-controlling fracture behaves as a dynamic characteristic of L-normal activity in the main metallogenic stage. The favorable site for occurrence is the partial extension expansion site where the fault structure goes northward and tends to steep dip. The ore body is voluntarily shifted to the side of SW with an angle of 40 ° ~ 70 ° at its side and remains equidistantly distributed as a whole. Based on the analysis of the ore-bearing lower limit of the area and the spatial pattern of ore body production, it is concluded that the second mineralized enrichment zone may occur along the direction of the SW lateral volcanoes of ore bodies IV and Ⅶ.
