| 摘 要： | 秦岭造山带属于中央造山带的重要组成部分,由不同时期,不同类型造山作用所形成的各种构造带复合组成,具复杂时空组合关系,成为一个特色鲜明的大陆造山带,故对其研究一直热度不减。本文从秦岭造山带中各种中酸性岩的Zr、Hf地球化学行为入手,通过对比不同时代、不同岩性中Zr、Hf的含量及Zr/Hf比值,分析Zr、Hf,在不同时代、不同SiO2含量的岩浆中的特性及演化规律,以此探讨秦岭造山带中岩浆在不同时代和不同构造背景下的演化规律。

| Abstract: | The Qinling orogenic belt is an important part of the Central orogenic belt and composed of various structure zones which were formed by different orogenic actions in different periods,being a distinctive continental orogenic belt with complex spatial and temporal relations.This paper makes an approach to evolutionary law of magmatism in the Qinling orogenic belt in different tectonic settings and in different times by means of Zr and Hf contents and Zr/Hf ratios in the various intermediate-acid rocks. |
