拉萨地体东南缘的多期深熔作用及动力学

The Lhasa terrane located between the Bangonghu-Nujiang suture and the lndus-Yalung Tsangpo suture in the Tibet Plateau which Precambrian crystalline basement underwent the amphibolite- to granulite-facies regional metamorphism and intense migmatization.Two phases of anatexis are recognized in the studied area.Firstly,granodioritic veins were formed by partial melting of amphibolite,and then these veins together with the country-rocks were metamorphosed to biotite-plagioclase gneiss;Secondly,garnet- rich pl...
