中文摘要:热液矿床的成矿物质往往具有多来源性。因此，定量判别不同来源矿质的量比关系，从而正确地识别矿床的主要成矿物质来源和成因机制，是现代矿床学研究的关键性问题之一。本文给出了三元混合模式的同位素一成矿元素的比值型判别方法，并给出了金银和萤石矿床成矿物质来源的定量判别应用实例。
Abstract:Ore-forming materials of hydrothermal deposits are commonly characterized by multiple sources. Therefore, the quantitative discrmination of ore materials from different sources and, furthermore, the recognition of the principal ore material source and the genetic mechanism of the ore deposit seem to be one of the key problems in the ore deposit study. In this paper, an isotope-metallogenic element ratio type discriminant equation of ternary mixed model is proposed: Some examples of applying quantitative discrimination are given in this paper, illustrating the sources of metallogenic materials for gold-silver and fluorite deposits.
