本文将分形几何学的原理和方法应用于江西德兴斑岩铜矿田三组断裂系统的二维平面分布特征研究,发现在研究的标度范围内不仅具有统计自相似性,而且不同矿区子区域具有不同的分维数D值。矿化岩体产出部位分维值明显高于整个矿田分维值,NE向断裂体系分维值略高于WNW向体系分维值。结合断裂产状、时代、穿切关系与岩体侵入部位对比可知,分维值越高,越有利于矿床形成,矿床规模也越大,其中NE向和WNW向断裂体系起主导控矿作用。
In this paper, the principle and method of fractal geometry are applied to the study of two-dimensional plane distribution characteristics of three sets of fault systems in Dexing porphyry copper field in Jiangxi Province. It is found that not only statistical self-similarity is found in the scale of the study, Regions have different fractal dimension D values. The fractal dimension of the mineralized rock mass is obviously higher than the fractal value of the whole ore field. The fractal dimension of the NE fracture system is slightly higher than the WNW fractal dimension. According to the correlation between fault occurrence, age, permutation and intrusive parts of rock mass, the higher the fractal dimension value, the more favorable the deposit formation and the larger the deposit size. The NE and WNW fracture systems play a dominant role.
