本文对环太平洋地区53个与斑岩钼、铜矿床有成因联系的侵入岩体的控矿专属性进行了研究。对矿化类型与岩石化学组分之间的关系进行了统计分析和对比,从而阐明了矿化类型与岩浆演化之间的关系。作者在传统的岩石化学研究方法基础上,进一步应用R型聚类分析和因子分析等多元统计方法提取有用信息。并从应用角度,运用模糊集合论中隶属函数的概念,研究已知控矿岩体矿化类型的划分,建立评价矿化岩体矿化类型的数学模型。
In this paper, we studied the ore-controlling specialties of 53 intrusions that are genetically linked to porphyry molybdenum and copper deposits in the Pacific Rim. The relationship between mineralization types and petrochemical components was statistically analyzed and compared to clarify the relationship between mineralization types and magmatic evolution. Based on the traditional research methods of petrochemistry, the author further uses multivariate statistical methods such as R-type cluster analysis and factor analysis to extract useful information. And from the application point of view, the concept of membership function in fuzzy set theory is used to study the division of mineralization types of controlled ore body and the mathematical model to evaluate mineralized type of mineralized rock mass is established.
