TL;DR: In this paper, the authors reported the first example of such magmas from southern Tibet in an active continental collision environment, and their overall geochemical characteristics suggest an origin by melting of eclogites and/or garnet amphibolites in the lower part of thickened Tibetan crust.

TL;DR: The first in situ Hf and U-Pb isotope analyses of zircon separates from Mesozoic granites in southern Tibet identify a significant, previously unknown stage of magmatism as discussed by the authors.

TL;DR: In this article, a geochronological study with 25 SHRIMP zircon U-Pb ages from the Gangdese Batholith was conducted to better delineate the magmatic duration.

TL;DR: In this article, a comparative analysis of whole-rock rare earth element geochemistry and zircon Hf isotopes between the adakites and associated Gangdese igneous rocks suggests that the Tibetan crust underwent a major phase of tectonic thickening between ca. 45 and 30 million years ago in the region.

TL;DR: In this paper, the authors report new 40Ar/39Ar age results for the volcanic rocks recovered from a large area (29°N to 32°N and 85°E to 93°E) that, together with literature data, delineate two discrete stages of volcanism.
