Fingerprinting metal transfer from mantle.
Zengqian Hou,Rui Wang +1 more
TL;DR: The Au-Te fingerprints of post-subduction magmas reveal an important role for the metasomatized sub-crustal lithospheric mantle in the formation of porphyry and epithermal copper deposits.

Highly fractionated Himalayan leucogranites and associated rare-metal mineralization
Fu-Yuan Wu,Xiao-Chi Liu,Zhi-Chao Liu,Rucheng Wang,Lei Xie,Jia-Min Wang,Wei-Qiang Ji,Lei Yang,Chen Liu,Gautam Prashad Khanal,Shao-Xiong He +10 more
TL;DR: The formation of the Himalaya was associated with the exhumation of high-grade metamorphosed rocks of the Higher Himalayan sequence (HHS) complex, which underwent amphibolite-, granulite- to eclogite-facies metamorphism and anatexis as discussed by the authors.
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.

Porphyry mineralization in the Tethyan orogen
TL;DR: The Tethyan metallogenic domain (TMD) is one of the three major domains in the world, and has developed several world-class mines, such as porphyry deposits, epithermal deposits, VMS deposits, chromite deposits, and orogenic gold deposits as discussed by the authors.

TTG generation by fluid-fluxed crustal melting: Direct evidence from the Proterozoic Georgetown Inlier, NE Australia
Amaury Pourteau,Luc Serge Doucet,Eleanore Blereau,Silvia Volante,Tim E. Johnson,William J. Collins,Zheng-Xiang Li,David C. Champion +7 more
TL;DR: In this paper, the authors demonstrate that the geochemical signature of the Georgetown TTG suite in the Georgetown Inlier, NE Australia, was derived from partial melting of spatially-associated mafic rocks in a post-collisional setting.

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.

Zircon trace element geochemistry: partitioning with garnet and the link between U–Pb ages and metamorphism
TL;DR: In this article, the trace element distribution coefficients between zircon and garnet were analyzed for trace elements using LA-ICP-MS and SHRIMP ion microprobe.

Porphyry Copper Systems
TL;DR: Porphyry Cu systems are the most widely distributed mineralization types at convergent plate boundaries, including porphyry deposits centered on intrusions; skarn, carbonate-replacement, and sediment-hosted Au deposits in increasingly peripheral locations; and superjacent high and intermediate-sulfidation epithermal deposits as mentioned in this paper.
