We present integrated in situ zircon U–Pb and Hf isotope data, along with whole‐rock and mineral chemistry data for the Salari granite of western Arunachal Himalaya to constrain its emplacement age, origin, and geodynamic evolution. The investigated Salari granites are high Fe2O3, CaO, and Nb, and low SiO2 and Rb/Sr ratio with fractionated rare earth element patterns ((Ce/Yb)N = 9.90–20.24) and minor...
Plutonic and porphyritic intrusions of adakitic rocks are widely distributed in the southern part of the eastern Pontides orogenic belt in Turkey. Ranging in age from late Paleocene to early Eocene, these intrusions provide critical information to evaluate the early Cenozoic geodynamic evolution of the eastern Mediterranean region. Here we report the results from our field, petrologic, geochemical...
Before the continental collision of India with Asia, northward subduction of the Tethyan oceanic lithosphere beneath South Asia resulted in widespread arc magmatism in the Lhasa terrane of southern Tibet from Early Jurassic to Eocene time. The detailed magmatic history of this Transhimalayan arc system, however, remains unclear. Here we report in-situ detrital zircon U–Pb and Hf isotopic analyses...
