The Qinling orogen was ultimately formed by suturing of the South Qinling and Yangtze blocks, but the exact timing of the final amalgamation of the two blocks has not been well established so far. Partial melting of the Qinling orogenic continental crust resulted in the generation of migmatites, and such rocks may help to decipher the chronology of such event. In this paper, we report U–Pb ages, trace...
Amphibole-bearing migmatites from the North Dabie Zone in the Dabie Mountains were investigated in order to constrain the partial melting process. These migmatites are characterized by large euhedral poikilitic amphiboles with abundant inclusions of plagioclase, biotite, and quartz in leucosome and melanosome. The amphiboles show large variations in REE compositions, which is interpreted as the result...
