福建省铅锌矿床主要金属矿物中微量元素统计特征及其与成因类型的关系

利用锅锌矿床中方铅矿、闪锌矿单矿物中微量元素Ａｇ、Ｓｉ、Ｃｄ、Ｍｎ的含量，应用数学地质的方法将参加统计的铅锌矿床划分为四种类型．同时描述了各类型矿床单矿物中微量元素的统计特征及其与成因类型之间的关系．由工作结果看到．单矿物中微量元素的统计特征可为矿床成因类型的划分提供比较客观的依据，方铅矿中的微量元素比闪锌矿判别能力更强．

The Relationship Between the Statistical Characteristics of Trace Elements of Major Metallic Minerals of Fujian Pb-Zn Deposits and Their Genetical Types

8 Pb-Zn deposits in Fujian province are classified into 4 types according to their contents or trace elements Ag, Cd, Bi, Mn.etc.in galena and sphalerite, by means of the methodology of mathematical geology.The relationship between the statistical characteristics of trace element in minerals from different types of deposits and their genetical types is also described herein.It can be seen from the result that the statistical characteristics of trace ele- ments of mono-minerals provide rather objective basis for the genetical classfication of Pb-Zn deposits.Galena is considered to show better discernment than sphalerite is.
