摘要
长乐—南澳构造带由于其特殊的地质构造背景,形成诸多具有典型意义的地质构造现象,岩浆混合作用形成的各类地质现象是其中的一类,通过对大量野外资料的分析,将岩浆混合作用划分为3个不同阶段,并结合区域构造背景探讨了各个阶段岩浆混合作用发生的机制,对进一步研究该构造带提供了重要的信息。
There are many typical and significant geological structures in the Changle-Nan＇ao tectonic belt which has many specific geological structures, one kind of which the deferent geologic structures formed by the magmatic mixing are. Based on the a great quantity of field geological data, it is considered that the magmatic mixing can be divided into three stages. In the paper, it makes a study of the mechanism of deferent magmatic mixing according to the background of regional geologic structures, which makes an offer of some important information for further research of the Changle-Nan＇ao tectonic belt.
