U–Pb age and Hf isotopic constraints of detrital zircons from the Himalayan foreland Subathu sub-basin on the Tertiary palaeogeography of the Himalaya

Detrital zircon U–Pb ages of the Proterozoic metaclastic-sedimentary rocks in Hainan Province of South China: New constraints on the depositional time, source area, and tectonic setting of the Shilu Fe–Co–Cu ore district

“…The successions and occurrences of the Shilu Group and overlying Shihuiding Formation are consistent with the features of foreland basins described by Burke et al (1986) and Ravikant et al (2011), which can be summarized as follows: (1) the transverse cross section of both successions is wedge-shaped, thickest in the SEE section and taping toward NWW ( Fig. 1b; also see Fig.…”

Provenance of Early Paleozoic metasediments in the central Chinese Altai: Implications for tectonic affinity of the Altai-Mongolia terrane in the Central Asian Orogenic Belt

“…In the East Antarctica Block, the age spectrum is relatively simple and dominated by late Mesoproterozoic ages with a strong peak at 1.14 Ga, with minor zircon groups formed at~2.7 and~2.45 Ga (Bisnath et al, 2006;Clark et al, 2012;Grew et al, 2012;Marschall et al, 2013). The main zircon populations of the northern India Block have pre-Neoproterozoic age peaks at 2.55 and 1.77 Ga slightly older than those of the Tarim Craton, with more extensive Neoproterozoic magmatic records with peaks at 1178, 979 and 609 Ma (Decelles et al, 2004;Gehrels et al, 2006;Kaur et al, 2011;McKenzie et al, 2011;Ravikant et al, 2011). The age distribution of the South China Block is similar to that of the Tarim Craton, characterized by three age peaks at 2.48, 1.85 and 0.8 Ga (Wan et al, 2007;Wang et al, 2007Wang et al, , 2010bXu et al, 2007;Sun et al, 2009;Yu et al, 2010;Li et al, 2011).…”

“…Comparing relative probability plots for detrital zircons from the Paleozoic metasediments in the Chinese Altai and detrital zircons from several other blocks. Original data are from the references: the Chinese Altai ; and data in this study), the North China Craton (Darby and Gehrels, 2006;Zhou et al, 2008;Wan et al, 2011;Liu et al, 2012bLiu et al, , 2013, the Siberia Craton (Khudoley et al, 2001;Wang et al, 2011;Gladkochub et al, 2013), the Tarim Craton Zhang et al, 2011Zhang et al, , 2012Zhu et al, 2011;Wang et al, 2013), the Yilgarn Craton (Cawood et al, 2003;Veevers et al, 2005;Pidgeon and Nemchin, 2006), the Gawler Craton (Swain et al, 2005;Belousova et al, 2009), the East Antarctica Block (Bisnath et al, 2006;Clark et al, 2012;Grew et al, 2012;Marschall et al, 2013), the northern India Block (Decelles et al, 2004;Gehrels et al, 2006;Kaur et al, 2011;McKenzie et al, 2011;Ravikant et al, 2011), and the South China Block (Wan et al, 2007;Wang et al, 2007Wang et al, , 2010bXu et al, 2007;Sun et al, 2009;Yu et al, 2010;Li et al, 2011). materials for the Early Paleozoic metasediments in the Chinese Altai. Therefore, we suggest that the Tarim Craton is most likely the main source of old detritus of the Early Paleozoic metasedimentary rocks in the Chinese Altai, which therefore suggests that the whole AltaiMongolia terrane has a close tectonic affinity to the Tarim Craton.…”

Geological characteristics and age of the Dahongliutan Fe-ore deposit in the Western Kunlun orogenic belt, Xinjiang, northwestern China

“…The direct evidence for synchronous magmatic rocks or contemporaneous metamorphic or deformational events have not yet been found in the Tianshuihai terrane, the Late NeoproterozoicCambrian ages obtained in our study suggest the existence of a provenance from which these zircons were sourced. Detrital zircon age peaks of 690, 625, 620 and 618 Ma have been reported in the Tarim-, Qiangtang-, Lhasa-, and Himalaya blocks (Dong et al, 2011;He et al, 2011;Ravikant et al, 2011;Zhu et al, 2011a,b;He et al, 2014). Also, the 660-610 Ma magmatic rocks, including the potassic granitoids (Ge et al, 2012), peraluminous granite (Luo et al, 2011) and mafic dykes (Zhu et al, 2008(Zhu et al, , 2011a in the northern Tarim Craton, have been reported.…”
