The genesis of continental collision-related porphyry Cu deposits (PCDs) remains controversial. most common hypothesis links their with magmas derived from subduction-modified arc lithosphere. However, it is unclear whether a genetic linkage exists between collision- and subduction-related PCDs. Here, we studied Jurassic Cu-Au Miocene Cu-Mo in south Tibet. PCDs occur only the western segment arc, which has depleted mantle-like isotopic compositions [e.g., (87Sr/86Sr)i = 0.7041–0.7048; εNd(t)...
This study summarizes the Assessment Report on Environmental Changes over Tibetan Plateau.In that report, a set of indicators under six categories-climate, bodies water, ecosystem, land surface environment, effect human activities, and hazard risk-is used to depict past changes, present status, future scenarios Plateau environment.Similar other assessments, exercise deals with evaluating existing scientific evidence (typically published in peer-reviewed journals) concerning policy and/or...
Most porphyry Cu deposits in the world occur magmatic arc settings and are formed association with calc-alkaline magmas related to subduction of oceanic lithosphere. This contribution reviews a number significant eastern Tethyan metallogenic domain. They widely variety non-arc settings, varying from post (late)-collisional transpressional extensional environments intracontinental orogenic anorogenic processes. Their spatial–temporal localization is controlled by strike–slip faults,...
We have investigated a suite of Miocene high-Mg diorite porphyries from Qulong in southern Tibet, the largest porphyry Cu–Mo deposit China. Laser ablation inductively coupled plasma mass spectrometry zircon U–Pb dating shows that was emplaced at 15·7 ± 0·2 Ma, which is slightly younger than adakite-like Rongmucuola pluton (c. 19·5–16·4 Ma). The diorites phenocrysts showing disequilibrium textures and include high-Mg# clinopyroxene (0·91–0·97). These rocks exhibit both ultrapotassic features,...
Porphyry copper deposits (PCDs) in Iran are dominantly distributed Arasbaran (NW Iran), the middle segment of Urumieh–Dokhtar Magmatic Arc (UDMA), and Kerman (central SE with minor occurrences eastern Makran arc. This paper provides a temporal–spatial geodynamic framework Iranian porphyry Cu (Mo–Au) systems, based on geochronologic data obtained from zircon U–Pb molybdenite Re–Os dating host porphyritic rocks molybdenites 15 major PCDs. The results define long metallogenic duration (39–6...
Generation of continental crust in collision zones reflect the interplay between oceanic subduction and collision. The Gangdese southern Tibet developed during Neo-Tethyan slab Mesozoic prior to reworking India-Asia Cenozoic. Here we show that arc magmatism started with fractional crystallization form cumulates associated medium-K calc-alkaline suites. This was followed by a period commencing at ~70 Ma dominated remelting pre-existing lower crust, producing more potassic compositions....
The continental crust in the overriding plate of India-Asia collision zone southern Tibet is characterized by an overthickened layer felsic composition with underlying granulite-eclogite layer. A large data set indicates that this experienced magmatism from 245 to 10 Ma, as recorded Gangdese Batholith. Magmatism was punctuated flare-ups at 185−170, 90−75, and 55−45 Ma caused a combination external internal factors. growth starts period dominated fractional crystallization formation...

Abstract Carbonatite-associated rare-earth-element (REE) deposits are the most significant source of world’s REEs; however, their genesis remains unclear. Here, we present new Sr-Nd-Pb and C-O isotopic data for Cenozoic carbonatite-hosted giant REE in southwest China. These located along western margin Yangtze Craton that experienced Proterozoic lithospheric accretion controlled by strike-slip faults related to Indo-Asian continental collision. The carbonatites were emplaced as stocks or...
The Beiya ore deposit is located in the northwestern Yangtze Block, to southeast of Tibetan Plateau, SW China. hosted by a porphyritic monzogranitic stock that cross-cut granite and later lamprophyre dikes. whole-rock geochemistry monzogranite intrusions both potassic adakite-like, as evidenced high K2O/Na2O (2.2 24.8), Sr/Y (53.2 143.2), (La/Yb)N (4.9 28.9) ratios. Both have comparable zircon U–Pb ages ca. 36 Ma εHf(t) values − 6.8 + 2.7. Zircons within these Hf isotope crustal model with...
