Many LIPs around the world possess world-class Ni–Cu–PGE magmatic oredeposits, such as the Siberian Traps and the Bushveld Complex (Naldrett, 1999,2004). Although so far no Ni–Cu–PGE deposits have been found in the Tarim LIP,a number of coeval Ni–Cu–PGE m...[继续阅读]

    Flood basalts that erupted on the continent are generally inevitably contaminatedby crustal materials (Arndt and Christensen, 1992). The large variations of Th/Nbratios and Sr–Nd–Hf isotopes among basalts from different groups (Figs. 3.6 and3.7) suggest t...[继续阅读]

    Tian et al. (2010) did the LA-ICP-MS zircon U–Pb dating for rhyolites in the NTUas follows. Rhyolites interlayered with basalts are interpreted to be roughly coevalwith their surrounding flood basalts. Two such samples of rhyolites were targetedin an atte...[继续阅读]

    The Tarim LIP is most readily considered as a result of mantle plume beneaththe Tarim Block in the Early Permian (Tian et al., 2010; Yang et al., 2013; Zhouet al., 2009; Pirajno et al., 2008; Zhang CL et al., 2008), just as most of the LIPsaround the worl...[继续阅读]

    The overall outputs of the Tarim LIP can be attributed to two stages of magmatismrelated to the mantle plume. During the early stage, the magmas were from thepartial melting of sub-continental lithosphere mantle (SCLM) which was heatedby the extreme hot u...[继续阅读]

    It is apparent that the crust/lithosphere will probably uplift due to the underplatingof hot plume (Campbell and Griffiths, 1990; Saunders et al., 2007). This has beenproved by many examples of plume-induced LIPs. The crust of the North AtlanticOcean is s...[继续阅读]

    For both the Tarim Basin and the Tianshan area, there were a lot of magmaticactivities during the Permian period, with various igneous rocks outcropped, suchas basalt, andesite, diabase, gabbro, trachyte, rhyolite, volcanic breccia, tuff andso on. For eas...[继续阅读]

    The geodynamic model is greatly dependent on the geochemical relations amongthe different components of the Tarim LIP, i.e. ultramafic rocks, basalts of theKeping Group and the Tabei Group, diabases from different parts of the block,syenites and syenitic ...[继续阅读]

    The new geochronological data from the Wajilitag kimberlitic intrusions supportedthe theory of the arrival of the mantle plume beneath the Tarim lithosphereat least 10 million years before the onset of the Tarim flood basalt volcanism(Zhang et al., 2013)....[继续阅读]
