Hf isotopic characteristics of the Tarim Permian large igneous province rocks of NW China: Implication for the magmatic source and evolution

The Early Permian Tarim Large Igneous Province: Main characteristics and a plume incubation model

“…These dates therefore constrain the emplacement of the intrusions and dykes between 278 and 284 Ma. The Wajilitag mafic-ultramafic intrusions have an OIB-like composition and are therefore derived from a similar source to the mafic dykes Li et al, 2012b). It has been proposed that large amounts of Fe-Ti oxides formed by crystallization of Fe-Ti rich melt under high fO 2 and a volatile-rich condition during the late-stage of magmatic differentiation .…”

High-alumina basalts from the Bogda Mountains suggest an arc setting for Chinese Northern Tianshan during the Late Carboniferous

“…Modern arcs: Singer et al (2007) and Simon et al (2014). Large igneous provinces: Li et al (2012), Wei et al (2014), Zhang et al (2006). Through wet melting experiments and direct measurements of H 2 O in melt inclusions, many workers believe that water (H 2 O N 2%) plays a dominate role in the formation of calc-alkaline HAB (Ariskin, 1999;Beard and Lofgren, 1992;Grove et al, 2012;Kelley et al, 2010;Grove, 1993a, 1993b).…”

Origin of the early Permian Wajilitag igneous complex and associated Fe–Ti oxide mineralization in the Tarim large igneous province, NW China

“…6). It has been argued that the Tarim basalts, which were mainly emplaced at $290 Ma, were likely derived from a subcontinental lithospheric mantle source metasomatized by subduction-related processes (Li et al, 2012b). The shift of magma source in the Tarim LIP from lithospheric mantle ($290 Ma) to asthenosphere ($280 Ma) is attributable to plume incubation under the thick Tarim craton, followed by deflection of the plume towards the cratonic margins with thin lithosphere Wei et al, 2013).…”

“…Thus, the syenites are interpreted as results of fractional Zhang et al (2010a). Data for the Tarim basalts are from Li et al (2012b), Yu et al (2011) andZhou et al (2009) Salters (1996) and Wilson (1989). The OIB array being from Chauvel et al (2008).…”
