“…The Triassic strata were deformed and metamorphosed between circa 51 and circa 44 Ma (Dunkl et al, ; Ratschbacher et al, ). Crustal thickening is also indicated by 48–45 Ma metamorphic zircon growth within the Yardoi gneiss dome in the Tethyan Himalaya (Ding et al, ). The single young circa 18 Ma white mica grain age from SWK does not provide enough data to describe a cooling age population.…”

New data from the lower Miocene Dumri Formation of western Nepal document exhumation of the Himalayan fold‐thrust belt and provenance of the Neogene foreland basin system. We employ U‐Pb zircon, Th‐Pb monazite, 40Ar/39Ar white mica, and zircon fission track chronometers to detrital minerals to constrain provenance, timing, and rate of exhumation of Himalayan source regions. Clusters of Proterozoic–early Paleozoic (900–400 Ma) Th‐Pb monazite and 40Ar/39Ar white mica detrital ages provide evidence for erosion of a Greater Himalayan sequence protolith unaffected by high‐grade Eohimalayan metamorphism. A small population of ~40 Ma cooling ages in detrital white mica grains shows exhumation of low‐grade metamorphic Tethyan Himalayan sequence through the ~350 °C closure temperature along the Tethyan Frontal thrust (proto‐South Tibetan detachment) during the late Eocene. Dumri Formation detritus shows a ~12 Myr time difference between cooling of its source rocks through the ~350 and ~240 °C closure temperatures as recorded by ~40–38 Ma youngest peak cooling ages in 40Ar/39Ar detrital white mica and ~28–24 Ma youngest populations in detrital zircon fission track. Exhumation between circa 40 and 28 Ma is consistent with slip and exhumation along the Main Central Thrust. Combined with similar data from northwestern India, our study suggests west‐to‐east spatially variable exhumation rates along strike of the Main Central Thrust. Our data also show an increase in exhumation during middle Miocene–Pliocene time, which is consistent with growth of the Lesser Himalaya duplex.

“…Nevertheless, significant debates still exist on possible links between global climate change and the India-Asia continent collision (Kerrick and Caldeira, 1999;Willenbring et al, 2013), because silicate weathering in response to plateau uplift sequesters carbon (Raymo and Ruddiman, 1992;Dosseto et al, 2015), whereas syn-collisional volcanism (e.g. Mo et al, 2008;Niu et al, 2013;Zhu et al, 2015), post-collisional volcanism (Guo et al, 2006(Guo et al, , 2007(Guo et al, , 2013(Guo et al, , 2014a(Guo et al, , 2015a, subduction zone metamorphism (Kerrick and Connolly, 2001;Cook-Kollars et al, 2014) and modern hydrothermal activities (Guo et al, 2014b;Zhang et al, 2014Zhang et al, , 2016 release carbon. Additionally, chemical geodynamics of volatile recycling at mid-ocean ridge (MOR; Graham, 2002;Stagno et al, 2013;Burley and Katz, 2015;Kagoshima et al, 2015) and oceanic subduction zone (OSZ; Sano and Williams, 1996;Lee and Lackey, 2015;Kelemen and Manning, 2015;Zellmer et al, 2015) have been well established, while little attention has been paid to volatile recycling at continental subduction zone (CSZ) and continental collision zone (CCZ), which highlights the importance of investigating flux and origin of volatiles (e.g., CO 2 ) from continental subduction zone.…”

“…The India-Asia continent collision at 55-50 Ma (e.g., Najman et al, 2010;Bouilhol et al, 2013;Zhu et al, 2015;Ding et al, 2016), accompanied by subsequent underthrusting of the Indian continental lithosphere beneath the Asian continent (e.g., DeCelles et al, 2011;Capitanio and Replumaz, 2013;Wang et al, 2014;Shi et al, 2015), led to formation of the Tibetan Plateau with an average elevation about 5000 m above sea level (Fielding et al, 1994), which has been widely invoked as critical geological event responsible for global cooling, central Asian aridification and East Asian monsoon intensification in the Cenozoic (e.g., Guo et al, 2002;Dupont-Nivet et al, 2007;Clift et al, 2008;Wu et al, 2012;Zheng et al, 2015).

“…The North Himalayan gneiss domes (NHGD) are located in the northern part of the South Tibetan detachment system (STDS). From east to west, the dome belt is composed of the Yalaxiangbo (Yardoi; Ding, Zhang, Dong, et al, ; Ding, Zhang, Hu, et al, ), Ramba (Z. C. Liu, Wu, Ji, Wang, & Liu, ), Kangmar (Wagner, Lee, Hacker, & Seward, ), Kampa (X. C.

Those gneiss domes can be used to better understand the crustal anatexis, magmatism, and orogeny in the Himalayan terrane (Zhang et al, ).…”

The Cuonadong Dome in southern Tibet is a newly discovered gneiss dome in the Tethys Himalaya. Here, we investigate the Late Cambrian augen gneiss (orthogneiss) within the core of this dome to address the controversy surrounding early Palaeozoic tectonic evolution of the northern margin of eastern Gondwana. We report new zircon laser ablation multicollector inductively coupled plasma mass spectrometry (LA‐(MC‐)ICP‐MS) U‐Pb ages, Lu‐Hf isotopes, whole‐rock major and trace element geochemistry, and Sr‐Nd‐Pb data on representative samples from the granitic gneiss. The weighted mean of 116 analyses of zircon grains yields an age of 498.2 ± 1.5 Ma (mean square weighted deviation [MSWD] = 1.2). Forty‐one spots analyses on these grains show consistent εHf (t) values of −2 to +4 (average = +1.1), corresponding to Hf crustal model age (TDM2) of 1.3 to 1.6 Ga (average = 1.39 Ga). The orthogneiss (metagranite) is characterized by high Si and K contents, with low Al, Mg, and Ti, and A/CNK values ranging from 0.87 to 0.98 with an average of 0.92, indicating a metaluminous composition and I‐type granitoid affinity. The granitoid displays significant enrichment in light rare earth elements (LREEs) and relatively flat high rare earth element (HREE) patterns, with strong negative Eu anomalies (Eu/Eu* = 0.26–0.31). The primitive mantle‐normalized trace elements show a relative enrichment in large‐ion lithophile elements, such as Rb, and high‐field strength elements, such as Th, U, Zr, and Hf, with depletion in Ba, Nb, Ta, Sr, P, and Ti. The rocks show high initial 87Sr/86Sr ratios (0.7221–0.7248) and low εNd (t) values (−8.9 to −7.3) with Nd model ages (TDM) of 1.79–1.91 Ga. Their radiogenic Pb isotopic compositions show (206Pb/204Pb)t = 18.804–19.110, (207Pb/204Pb)t = 15.730–15.768, and (208Pb/204Pb)t = 38.409–39.054, indicating an ancient upper middle continental crustal origin. Our study shows that the protolith of the metagranite was most likely derived from the partial melting of upper continental crust with a minor contribution of depleted mantle materials. Through integration of the regional information on early Palaeozoic magmatism and metamorphic events, we contend that the protolith of the Cuonadong granitic gneiss formed in an accretionary setting associated with the early Palaeozoic Proto‐Tethys Oceanic plate subduction beneath the Gondwana continent.
