摘要
本文的研究对象为造山带中与构造运动关系密切的动热变质岩，主要从微量元素地球化学、稀土元素地球化学、p－t特征、流体包裹体特征、同位素年代学特征等方面讨论了松潘－甘孜造山带中丹巴地区动热变质岩的原岩、化学组成、变质作用演化过程以及主要变质热事件发生的时间。
This paper deals with the thermodynamically metamorphic rocks related to the tectonic movementin the Songpan-Garze orogenic belt, Danba area. Based on trace elements, REE, p-t, fluid inclusionsand isotope geochronological characteristics, the paper presents the source rocks and the composition ofthe thermodynamically metamorphic rocks, metamorphic processes and the timing of major metamorphism in the Danba area.
