| 摘 要： | 根据泰宁何宝山金矿区的控矿构造特征的综合分析,认为何宝山金矿区断裂构造发育,主要有近南北向、北东向、北西向3组。北东向的断裂为导矿构造,南北向断裂为控矿构造。控矿断裂为2组近南北向的断裂裂隙群,具有明显的剪性特征,控制了金矿化蚀变带及金矿体的空间展布。近东西向断裂构造为成矿后期的,对南北向的控矿断裂构造具有破坏作用。金矿化蚀变体产于断裂破碎带内,明显受断裂控制。而金矿化程度与蚀变强弱、断裂的规模、破碎程度有直接相关。结合地质类比法,通过构造分析法及矿区地质条件、矿化特征综合分析,认为矿区F3断裂及弧形的拐弯处、F2-4断裂深部为矿体产出有利部位,矿区北部在断裂构造收敛部位、帚状构造砥柱边缘为寻找矿体有利地段。

| Abstract: | According to the comprehensive analysisi of the characteristics of ore-controlling stucture in Hebaoshan gold deposit of Taining county,the author thinks that there are the 3 group faults of nearly north-south,North-east and North-west.The NE fault is ore conducting structure and the NS fault is ore-controlling structure.The ore controlling fracture are 2 nearly NS trending fracture groups and has the obvious shear characteristics,its controlling the spatial distribution of gold mineralization and alteration belts and gold ore bodies.The gold mineralization of altered body produced in the fracture zone and are obviously controlled by fractures.There is a direct correlation between gold mineralization and alteration intensity,fracture scale and the degree of fragmentation.Combined with the geological analogy method,Through the structural analysis and comprehensive analysis of the mineralization geological conditions,and Mineralization characteristics,it considers that Mine F3 fracture,the corner arc and F2-4 fracture in deep are the orebody preserved favorable position.The north of the deposit in the fracture tectonic convergence site and Brush structure foundation edge are the advantageous region for looking for orebody. |
