英文摘要The Neo-Tethyan subduction that operated before the India-Asia collision resulted in an Andean-type convergent margin in South Asia and was associated with extensive arc magmatism that formed the Transhimalayan batholiths. Magmatism in the Gangdese Batholith, the largest batholith exposed in the Lhasa terrane of southern Tibet, is considered to have lasted from the early Jurassic to Eocene. However, eastward correlation of the Gangdese Batholith is uncertain because it is truncated by the eastern Himalayan syntaxis. Here, we report new data from the Lohit Batholith, NE India, including: (i) zircon U-Pb ages of five granitoids from ca. 148 to 96Ma; and (ii) zircon Hf isotopes of these rocks that yield high and positive epsilon(Hf)(T) values. We argue that the Lohit Batholith is the eastward extension of the Gangdese Batholith, and can be correlated southward to the Wuntho-Popa arc in West Burma, thus linking a prolonged Neo-Tethyan magmatic arc system from southern Tibet to Southeast Asia.
