实践证明笔者在探讨山西南部峨眉台塬存在隐伏铁矿的可能性,进行岩石特征对比过程中,通过研究各种主要参数之间的关系,探求出一种评价岩浆岩成矿性的综合指标,即铁碱协和系数,现提出仅供参考. 铁碱协和系数的地质意义理论依据多数人认为,岩浆活动是接触交代型铁矿成矿物质的主要来源,因此,研究与之有关的岩浆杂岩系特征,查明岩浆演化过程,就成为研究接触交代型铁矿成矿作用的主要途径之一.为此,必须研究岩石化学成分的变化,以揭
The practice proves that the author has probed into the possibility of concealed iron ore in the Emei platform plateau in the south of Shanxi Province. During the process of contrasting the characteristics of the rock, a comprehensive index for evaluating the mineralization of the magmatic rock was explored by studying the relationship among the various parameters, namely, Iron-basecoordination coefficients, are presented for reference only.Geological Significance of Iron-Basecoordination Coefficients Basis Most people believe that magmatic activity is the main source of contact with the ore-forming material of iron ore, so the study related magmatic complexes Characteristics, to identify the evolution of magmatism, has become one of the main ways to study the contact mineralization of iron ore For this reason, we must study the chemical composition of the rock changes in order to expose
