An Early Cretaceous garnet-bearing metaluminous A-type granite intrusion in the East Qinling Orogen, central China: Petrological, mineralogical and geochemical constraints

Paleozoic metamorphism in the Qinling orogen, Tongbai Mountains, central China

The Qinling orogen (Fig. 1) extends for over 2000 km across central China, separating the Archean and Proterozoic Sino-Korean block in the north from the Proterozoic Yangtze block in the south. Although the orogen has been recognized as a continental collision zone for some time, the nature, age, and duration of the collision have been the subject of considerable debate (see review in Hacker et...

40Ar/39Ar thermochronology from the northwestern Dabie Shan: constraints on the evolution of Qinling–Dabie orogenic belt, east-central China

Seven structural units with distinct kinematics have been recognized in the northwestern Dabie Shan (114°E– 115°E and 31°N–32°N), east-central China. They are, from north to south: (1) the north-verging Mafan fold belt (MFB) involving early Paleozoic metamorphic rocks; (2) the Liangting melange belt (LMB), which is separated from the MFB by a south-dipping thrust and consists of gneissic and ma...

U=Pb zircon ages constrain the architecture of the ultrahigh-pressure Qinling–Dabie Orogen, China

New SHRIMP and TIMS zircon ages, Ar=Ar ages, and eclogite locations contribute significantly to our understanding of the ultrahigh-pressure Dabie Shan. (1) The geographic extent of the Yangtze craton that was subducted to ultrahigh pressure extends to the northern edge of the Dabie Shan. (2) The northern half of the Dabie Shan is a magmatic complex, intruded over a 10-Myr interval between 137 a...
