火成岩系列划分的回顾与当代含义

本文对火成岩系列划分的历史演变进行了回顾,指出其当代含义的历史由来,以及与历史上某些概念的重大差别,旨在为消除已出现的某些混乱作出努力。本世纪上半叶,火成岩系列划分的概念中,亚碱性与钙碱性是作为同义语使用,而当代含义的钙碱性不等于亚碱性。国内有关文献中出现的某些概念上的混乱可能与对历史进程中这些概念的变化了解不够有关。

A Review oF the Classification of Igneous Rock Series and Its Present Meaning

This paper makes a historical review of the classification of igneous rock series, and points out how the modern idea of igneous rock series is developed as well as their difference in meaning in the past and at present, in order to clear up a misunderstanding as to the division of igneous rock series. In the first half of the twentieth century, the subalkalic and calc-alkalic series were synonymously used. However, the subalkalic rock series is not equivalent to the calc-alkalic series in the modern concept. The misunderstanding about the classification of igneous rock series in Chinese literature may be owing to little knowledge about the change in their meanings in the history.
