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...
متن کاملSimulations of crustal anatexis: Implications for the growth and differentiation of continental crust
There is overwhelming and incontrovertible petrological and geophysical evidence for the significant role played by mantle-derived mafic magma in the generation and growth of continental crust. Likewise, intrusion of mafic magmas beneath or into continental crust is very likely the major source of enthalpy that drives intracrustal differentiation. A simple dynamical model has been constructed t...
متن کاملConstraints from rocks in the Taiwan orogen on crustal stress levels and rheology
[1] Taiwan’s Hsüehshan range experienced penetrative coaxial deformation within and near the brittle-plastic transition between 6.5 and 3 Ma. This recent and short-lasting deformation in an active, well-studied orogen makes it an ideal natural laboratory for studying crustal rheology. Recrystallized grain size piezometry in quartz and Ti-in-quartz thermobarometry yield peak differential stresse...
متن کاملCrustal evolution in the East African Orogen: a neodymium isotopic perspective
The East African Orogen (EAO) is one of Earth’s great collision zones, where East and West Gondwana collided to form the supercontinent ‘Greater Gondwana’ or ‘Pannotia’ at the end of Neoproterozoic time. There is now sufficient Nd isotopic data for basement rocks of the EAO to yield a useful summary. A total of 449 samples were gleaned from the literature, recalculated to a common value for the...
