摘要
自相似性是指事物的一部分与其整体相似的性质。数学上与自相似性密切相关的是幂函数及分维(相似维)。本文从成矿作用时间演变、区域矿产分布、矿床空间分布、矿石矿物中元素和矿田构造形迹五个方面列举了矿床学中一些自相似现象;从经典地质学与现代物理学的角度分析了矿床学中自相似现象的形成机制;并指出矿床学中自相似现象的研究可为矿床成因分析提供信息,促进矿床研究的简化和定量化、提出新的研究课题、而且有利于矿床学与其它学科的渗透和综合。
Self-similarity is an attribute of things which means that there exists similarity between the whole and its component parts. The self-similarity is closely related to power functions and fractal dimensions in mathematics. This paper indicates the presence of self-similarities in economic geology in such aspects as the temporal evolution of mineralization, the regional distribution of mineral deposits, the location of ore deposits, the arrangement of chemical elements in ore minerals, and the structural features of ore fields and ore deposits.In the light of classical geology and modern physics the authors have discussed the formation mechanism of self-similarities in economic geology.The significance of the application of self-similarity to economic geology is pointed out in this paper: it can provide information for the analysis of ore deposit genesis, lead to the simplified and quantitative study of ore deposits and advance new research subjects; what is more, it contributes to the penetration and integration of economic geology and other disciplines.
