Potassic volcanic rocks and adakitic intrusions in southern Tibet: Insights into mantle–crust interaction and mass transfer from Indian plate
TLDR
In this article, a systematic study on the postcollisional potassic and adakitic rocks in order to investigate their petrogenetic links with the coeval mantle-derived ultrapotassic rocks and shed light on the potential input from underthrusted Indian continental crust is presented.About:

TL;DR: In this paper, a detailed study on the volcanic rocks of the Yeba Formation (YF) with the results offering insights into the ways in which the juvenile crust may be accreted in the southern Lhasa Terrane in the Jurassic.
Identifying Mantle Carbonatite Metasomatism through Os-Sr-Mg Isotopes in Tibetan Ultrapotassic Rocks
Dong Liu,Zhidan Zhao,Di-Cheng Zhu,Yaoling Niu,Elisabeth Widom,Fang-Zhen Teng,Donald J. DePaolo +6 more
TL;DR: In this article, a study of Os-Sr-Mg isotopes on the Oligocene-Miocene ultrapotassic rocks aimed at better understanding sediment subduction and recycling beneath southern Tibet is presented.

Inherited terrane properties explain enigmatic post-collisional Himalayan-Tibetan evolution
TL;DR: In this article, the authors use two-dimensional numerical geodynamical model experiments to show that the enigmatic behavior of the Himalayan-Tibetan orogeny can result from crust-mantle decoupling, transport of crust relative to the mantle lithosphere, and diverse styles of lithospheric mantle delamination, which emerge selfconsistently as phases in the evolution of the system.

TL;DR: In this article, a detailed investigation in the Lunpola basin of central Tibet and a new depositional age range of ca. 35 to 9 Ma was proposed, significantly younger than previously thought.

Chemical and isotopic systematics of oceanic basalt : implications for mantle composition and processes
TL;DR: In this article, trace-element data for mid-ocean ridge basalts and ocean island basalts are used to formulate chemical systematics for oceanic basalts, interpreted in terms of partial-melting conditions, variations in residual mineralogy, involvement of subducted sediment, recycling of oceanic lithosphere and processes within the low velocity zone.

Geologic Evolution of the Himalayan-Tibetan Orogen
An Yin,T. Mark Harrison +1 more
TL;DR: A review of the geologic history of the Himalayan-Tibetan orogen suggests that at least 1400 km of north-south shortening has been absorbed by the orogen since the onset of the Indo-Asian collision at about 70 Ma as discussed by the authors.

Correction of common lead in U-Pb analyses that do not report 204Pb
TL;DR: In this article, the authors proposed a correction method that neither uses 204Pb nor assumes concordance, but uses a numeric solution to a set of equations relating the content of radiogenic lead in a zircon or other U/Th-enriched mineral to its total lead content.

Derivation of some modern arc magmas by melting of young subducted lithosphere
Marc J. Defant,Mark S. Drummond +1 more
TL;DR: In this paper, the trace-element geochemical properties of the adakites (termed "adakites") of modern island and continental arcs are shown to be consistent with a derivation by partial melting of the subducted slab, and in particular that subducting lithosphere younger than 25 Myr seems to be required for slab melting to occur.
