| Abstract: | 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. |
