| [摘要]利用断裂构造的分维值可以定量描述断裂分布的复杂性和构造演化的成熟度,它是断层
数量、规模、发育程度、组合方式及动力学的综合体现。文章将分形几何学的原理和方法应用于九瑞地
区以及城门山和武山铜矿田的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,而且九瑞矿区子区域具有不同的分维数D 值。结果表明矿化岩体产出部位分维值明显
高于整个区域的分维值,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。 |

| Abstract:Fractal dimension can be used to quantify the complexity of the fracture distribution and its evolutional maturity. It is a synthetic character鄄
ization of fault amount, scale, evolution, assembly pattern and mechanism. Through the application of the principles and methods of fractal geometry to
the study of fractal characteristics of the Jiujiang-Ruichang area, both Chengmenshan and Wushan deposits. In the research of Jiujiang-Ruichang copper
deposit, the authors found that these fracture systems not only possess the statistical self-similar character in the scale extent studied, but also have differ鄄
ent D values of fractal dimension in different ore districts and fracture systems. The characteristic distribution of D values coupled with comparison of the
attitudes, penetration relationships and ages of different fracture systems with the location of porphyry copper deposit bodies indicates that the higher the D
value ,the more favorable the conditions of copper formation and larger the deposit size. |
