“…So far, two extreme models exist: the delamination model (e.g., Wu et al 2000Wu et al , 2003Gao et al 2002Gao et al , 2004Gao et al , 2008Chu et al 2009) and the thermal-mechanical erosion model (e.g., Griffin et al 1998;Menzies and Xu 1998;Xu 2001;Menzies et al 2007). In the delamination model, the thickened eclogitic lower crust, together with the lithospheric mantle below, delaminates into the convection mantle.…”

The geochemical characteristics of melt inclusions and their host olivines provide important information on the processes that create magmas and the nature of their mantle and crustal source regions. We report chemical compositions of melt inclusions, their host olivines and bulk rocks of Xindian basalts in Chifeng area, North China Craton. Compositions of both bulk rocks and melt inclusions are tholeiitic. Based on petrographic observations and compositional variation of melt inclusions, the crystallizing sequence of Xindian basalts is as follows: olivine (at MgO [ *5.5 wt%), plagioclase (beginning at MgO = *5.5 wt%), clinopyroxene and ilmenite (at MgO \ 5.0 wt%). High Ni contents and Fe/Mn ratios, and low Ca and Mn contents in olivine phenocrysts, combining with low CaO contents of relatively high MgO melt inclusions (MgO [ 6 wt%), indicate that Xindian basalts are possibly derived from a pyroxenite source rather than a peridotite source. In the CS-MS-A diagram, all the high MgO melt inclusions (MgO [ 6.0 wt%) project in the field between garnet ? clinopyroxene ? liquid and garnet ? clinopyroxene ? orthopyroxene ? liquid near 3.0 GPa, further suggesting that residual minerals are mainly garnet and clinopyroxene, with possible presence of orthopyroxene, but without olivine. Modeling calculations using MELTS show that the water content of Xindian basalts is 0.3-0.7 wt% at MgO = 8.13 wt%. Using 20-25 % of partial melting estimated by moderately incompatible element ratios, the water content in the source of Xindian basalts is inferred to be C450 ppm, much higher than 6-85 ppm in dry lithospheric mantle. The melting depth is inferred to be *3.0 GPa, much deeper than that of tholeiitic lavas (\2.0 GPa), assuming a peridotite source with a normal mantle potential temperature. Such melting depth is virtually equal to the thickness of lithosphere beneath Chifeng area (*100 km), suggesting that Xindian basalts are derived from the asthenospheric mantle, if the lithospheric lid effect model is assumed.

핵심어: 백악기초기, 동중국, 경상분지, 현무암, 암석권맨틀Abstract: Geochemical characteristics of the Early Cretaceous igneous rocks from eastern China and the Gyeongsang Basin, Korean Peninsula has been summarized. They have wide range of lithological variation with extrusive picrite-basalt-andesite-trachyte-rhyolite and lamprophyre, and intrusive gabbro-dioritemonzonite-syenite-granite and diabase in eastern China, mostly belonging to the high-K calc-alkaline or shoshonitic series. The volcanic rocks intercalated with the Hayang Group sedimentary assemblages in the Gyeongsang basin are high-K to shoshonitic basaltic trachyandesites. The Early Cretaceous basaltic rocks studied mostly fall within the field of within-plate basalts on the Zr/Y-Zr and Nb-Zr-Y tectonic discrimination diagrams. On a Sr-Nd isotope correlation diagram, basaltic rocks from the North China block (NCB) and the continent-continent collision zone (CZ) between the North and South China blocks plot into the enriched lower right quadrant along the extension of the mantle array.

“…The foundering of eclogitic lower crust and underlying lithospheric mantle implies complete removal of old lithosphere and subsequent replacement by juvenile lithosphere (Kay and Kay, 1993). However, mantle xenoliths entrained in Cretaceous lavas (e.g., Laiwu, Gao et al, 2008;Qingdao, Zhang et al, 2011;Fuxin, this study) and even Cenozoic lavas (Kuandian, Wu et al, 2006;Wudi, this study) that are far removed from the Tan-Lu fault contain remnants of original Precambrian, more refractory lithospheric mantle. By comparison, mantle xenoliths/xenocrysts in Cretaceous lavas erupted close to the fault have changed in composition through time, for example from pyroxenite xenoliths and low-Fo (88-91) olivine xenocrysts beneath Fangcheng (125 Ma; Zhang et al, 2002Zhang et al, , 2007 and websterite xenoliths and high-Fo (92-93) olivine xenocrysts beneath Feixian (119 Ma; Pei et al, 2004;Gao et al, 2008;Xu et al, 2013b) in the Early Cretaceous, to lherzolite xenoliths beneath Junan (67 Ma; Ying et al, 2006) in the Late Cretaceous.…”

“…By contrast, peridotite xenoliths carried in spatially associated Cenozoic basalts have Re-Os systematics similar to modern convecting upper mantle (e.g., Chu et al, 2009;Gao et al, 2002;Wu Tectonophysics 650 (2015) 104-112 et al, 2003, 2006), implying removal and replacement of the original Late Archean-Early Paleoproterozoic lithospheric mantle following the Ordovician, most likely during the Mesozoic. However, studies of mantle xenoliths erupted in the Mesozoic (e.g., Gao et al, 2008), or spatially distant from the Tan-Lu fault (e.g., Wu et al, 2006) are few, largely due to the scarcity of samples, as well as the very small size of those that do occur. The study of additional Mesozoic-erupted mantle xenoliths may be useful in constraining the temporal sequence and extent of lithospheric thinning in the eastern NCC.…”

Big insights from tiny peridotites: Evidence for persistence of Precambrian lithosphere beneath the eastern North China Craton

Previous studies have shown that the eastern North China Craton (NCC) lost its ancient lithospheric mantle root during the Phanerozoic. The temporal sequence, spatial extent, and cause of the lithospheric thinning, however, continue to be debated. Here we report olivine compositions, whole-rock Re-Os isotopic systematics, and platinum-group element abundances of small (b 2 cm in maximum dimension) mantle peridotite xenoliths from two basalt localities from the eastern NCC, Wudi (Cenozoic) and Fuxin (Cretaceous). These locations lie far (~150-200 km) from the Tan-Lu fault, which has been linked to lithospheric replacement in the eastern NCC. Peridotites at both locations have fertile to moderately refractory compositions (Fo b 91.5), while highly refractory (Fo N 92) lithospheric mantle is largely absent. Osmium isotopic data suggest the Wudi peridotites experienced melt depletion primarily during the Paleoproterozoic (~1.8 Ga), although an Archean Os model age for one xenolith indicates incorporation of a minor component of Archean lithospheric mantle. These data suggest that a previously unrecognized Paleoproterozoic orogenic event removed and replaced the original Archean lithospheric mantle beneath the sedimentary basin at the southern edge of the Bohai Sea. By contrast, the Fuxin peridotites, entrained in Cretaceous basalts that crop out along the northern edge of the eastern NCC, document the coexistence of both ancient (≥2.3 Ga) and modern lithospheric mantle components. Here, the original Late Archean-Early Paleoproterozoic lithospheric mantle was, at least partially, removed and replaced prior to 100 Ma. Combined with literature data, our results show that removal of the original Archean lithosphere occurred within Proterozoic collisional orogens, and that replacement of Precambrian lithosphere during the Mesozoic may have been spatially associated with the collisional boundaries and the strike-slip Tan-Lu fault, as well as the onset of Paleo-Pacific plate subduction.
