摘要
通过对张八岭隆起中段瓦屋刘岩体地球化学特征的研究,分析了岩浆源区特征与属性,为探讨该区构造-岩浆演化提供重要的信息。瓦屋刘岩体属高钾钙碱性岩系列,稀土元素、微量元素特征显示其为地壳深源物质部分熔融作用产物,并有源自交代地幔的热液流体参与。岩体地球化学特征与埃达克岩相近,形成于挤压、地壳加厚的构造背景。
Based on study of geochemical characteristics of the Wawuliu rock mass in the middle part of the Zhangba Uplift,this paper analyzes the features and properties of the magmatic source area,providing important information for discussion of tectono-magmatic evolution in this area.The Wawuliu rock mass is of high-K calc-alkaline series.The characteristics of rare earth elements and trace elements show that the rock is the product of partial melting of deep-source materials in the crust,and is also involved in hydrothermal fluid sourced from the metasomatic mantle.The rock mass is geochemically similar to adakite that is formed in a tectonic setting of compression and crustal thickening.
