Late Mesozoic extensional mechanisms in the Great Xing'an Range (GXR) and relevant crust-mantle interactions are complicated, which result in widespread magmatisms with diverse parental origins and petrogenesises. In this paper, we present the lithology, whole-rock geochemistry, and zircon U-Pb-Lu-Hf isotopes for granodiorite-monzogranite rocks (GM) and their enclaves of quartz monzodiorites in the Zhalantun area, east of central GXR. Zircon U-Pb dating results reveal that both GM rocks and their enclaves of quartz monzodiorites yield a nearly identical crystallization age of $125 Ma. The GM rocks exhibit weak peraluminous and high-K calcalkaline compositions with high SiO 2 , Na 2 O + K 2 O, and Al 2 O 3 contents, and low MgO, Mg # , Fe 2 O 3T , and TiO 2 contents, which are characterized by fractionated REE patterns, relatively strong negative Eu anomalies, enrichments of LILEs (e.g., Rb, Ba, and K), and depletions of Nb, Ta, P, and Ti. The parental origins for GM samples were juvenile crustal materials, with positive zircon ε Hf (t) values of +2.5 to +12.9. The whole-rock and zircon geochemical simulations limit slightly lower GM magma crystallization temperatures (T Ti-Zrn ) of 683-824 C and relatively more oxidizing conditions (log(fO 2 ) = FMQ+7.6-FMQ-6.8), and further confine that they were probably formed by $10-35% degrees of fluid-present partial melting of lower to middle crustal materials, with fractional crystallization and/or residual mineral phases of plagioclase, amphibole, clinopyroxene, and garnet. By contrast, the enclaves of quartz monzodiorites possess lower SiO 2 and Na 2 O + K 2 O compositions, but higher MgO, Mg # , Fe 2 O 3T , and TiO 2 values, which are consistent with metaluminous-weak peraluminous and high-K calc-alkaline series. All quartz monzodiorites exhibit subparallel right-declined REE patterns, negligible to none Eu anomalies, enrichments of LILEs, and depletions of Nb, Ta, and Ti. Combined with mineral morphology and disequilibrium structures, the whole-rock geochemical and Hf isotopic simulations imply that parental magmas for quartz monzodiorites were hybrid mixtures between $50% host GM acid magmas and $50% ancient crust compositions, with a wide range of zircon ε Hf (t) of +14.0 to À7.7, slightly higher T Ti-Zrn of 710-835 C, and lower log(fO 2 ) of FMQ+8.2-FMQ-10.5. Taken together, felsic plutons in the Zhalantun area

“…There is growing evidence that the lithosphere under WNCC has also been thinning in the Mesozoic (Chen et al, 2009;Guo et al, 2014) as evidenced by the widespread late Cretaceous volcanic rocks along north margin of WNCC (Fig. 1a; Guo et al, 2014Guo et al, , 2018He et al, 2013;Zhang, 2013;Zhong et al, 2014Zhong et al, , 2015Zou et al, 2008). These early Cretaceous basalts have high incompatible element abundances and highly enriched Sr-Nd-Hf isotopic compositions (e.g., Guo et al, 2014Guo et al, , 2018Zhong et al, 2014Zhong et al, , 2015, implying they also originated from an ancient metasomatized lithosphere mantle (Guo et al, 2014(Guo et al, , 2018.…”

U–Pb Dating and Trace Element Composition of Zircons from the Gujiao Ore-Bearing Intrusion, Shanxi, China: Implications for Timing and Mineralization of the Guojialiang Iron Skarn Deposit

The Gujiao ore field, located in the middle segment of the Lüliang Mountain in central North China Craton (NCC), is one of iron skarn deposits of western iron belt in China. The U–Pb dating results of zircon by LA-ICP-MS suggest that the ore-related monzonite from the Guojialiang deposit was formed at 129.7 ± 1.7 Ma, early Cretaceous, which is consistent with the timing of iron skarn deposits in the Handan–Xingtai district of western iron belt. The zircons of monzonite present notable positive Ce anomalies (Ce/Ce* = 23.38–45.85), high Ce4+/Ce3+ values (154–385) and relatively high oxygen fugacity (fO2 = −13.09 to −15.36), and yield relatively low Ti-in-zircon temperatures. The physico-chemical conditions of the Guojialiang deposit were quite similar to these of ore-bearing plutons in the Handan-Xingtai district. The ore-bearing magmas are derived from the enriched lithospheric mantle with crustal material contribution, which played key role in oxidation state of the magma and the iron mineralization in the western iron belt.
