诸如地球化学元素间的组合关系、地球物理和地球化学异常的分类与评价、矿床成因的推断解释、成矿远景区的划分等,往往都具有一定的模糊性。因此,应用模糊数学的原理和方法来解决地质—找矿问题,已渐引起广大地质工作者的重视。模糊相似优选比分析法是一种简明易行的模糊数学方法。本文以云南西盟锡矿田部分地球化学异常的分类和含矿性评价为例,简述其方法原理、实施步骤和效果。
Such as the combination between the geochemical elements, the classification and evaluation of geophysical and geochemical anomalies, the genesis of the interpretation of the interpretation of deposits, the division of the ore prospecting area, often have a certain degree of ambiguity. Therefore, the application of fuzzy mathematics principles and methods to solve the geological - prospecting problems, has gradually attracted the attention of the majority of geological workers. Fuzzy similar preference ratio analysis is a kind of concise and easy fuzzy mathematical method. In this paper, taking the classification and ore-bearing evaluation of some geochemical anomalies in the Ximeng tin ore field of Yunnan as an example, the method principle, implementation steps and effects are briefly described.
