Age and isotope geochemistry of magmatic rocks of the Lohit Plutonic Complex, eastern Himalaya: implications for the evolution of Transhimalayan arc magmatism

We present integrated in situ zircon U–Pb and Hf isotope data, along with whole-rock Sr–Nd isotope and geochemical data for plutonic rocks of the Lohit Plutonic Complex of eastern Himalaya to understand the age distribution and petrogenetic–tectonic evolution of the Transhimalayan batholiths in the eastern Himalaya. The plutonic rocks are gabbro, diorite and quartz-diorite in composition, have calc-alkaline signatures with metaluminous character...
