| 摘 要： | 本文讨论了如何改进岩石构造环境的地球化学判别方法及其应用于研究造山带构造演化的问题，在论述了岩石地球化学特征与形成构造环境关系实质的基础上，提出了优选判别指示元素，参数和方法的准则及应用实例；并提出采用岩套内岩类配套及相邻相造期岩套或岩石建造时空配套综合分析途径的建议，从解决某些岩石化学特征在反映构造环境方面存在的多解性问题，推动造山带构造演化细节的深入研究。

| Abstract: | This paper deals with the problem concerning geochemical discrimination of tectonic settings of rocks in order to diminish the wrong diagnoses and to improve the geochemical approach to the tectonic study The essential relation between the geochemical characteristics of a rock and its tectonic setting is discussed,so that the discriminating approach can be used more reasonably Then the optimum principles for selecting indicator elements and discriminating methods are suggested and the examples are given For the sake of overcoming ambiguities of the discriminations,a synthetical study of various rocks in a rock suite and of syntectonic rock suites is proposed |
