“…The primordial mantle-normalized plots of the alkali feldspar granites reflect the depletion of Sr, Ba, P, Ti, Nb, and Ta and suggest that feldspar (probably K-feldspar or plagioclase) was fractionated (low Sr and Ba) along with apatite (low P) and possibly titanite, rutile, and ilmenite (low Ti, Ta, and Nb; Figure 7f). The normal Fe contents of the A-type granites do not support the occurrence of ilmenite fractionation (Frost & Frost, 2011 setting (Fu et al, 2014;Fu et al, 2016), whereas the Nd-Sr isotopic compositions of both volcanic rocks indicate that they have a similar provenance as the intrusive rocks (Fu et al, 2014).

This study presents zircon U–Pb ages and geochemical and Sr–Nd isotopic data for acid granites from the Uliastai continental margin, which is located in the Ulaan Tolgoi area of the south‐eastern Central Asian Orogenic Belt (CAOB). Although most samples have similar calc‐alkaline (K2O/Na2O = 0.55–1.70, average of 1.35) and peraluminous (A/CNK = 1.02–1.20 and A/NK = 1.09–1.87) characteristics, the granodiorites, monzogranites, and alkali feldspar granites exhibit distinct light rare earth element (LREE)/heavy REE (HREE) anomalies, including negative Nb, P, Ti, Sr, and Ba anomalies and negative εNd(t) values. These characteristics indicate that this complex massif comprises lower Early Carboniferous subduction‐related calc‐alkaline granodiorites (348 ± 1 Ma); an upper Early Carboniferous syn‐collisional segment characterized by S‐type, high‐K, calc‐alkaline, and peraluminous monzonitic granites (334 ± 1 Ma); and Late Carboniferous post‐orogenic extensional A2‐type peraluminous alkali feldspar granites (317 ± 1 Ma). Previous studies performed on coeval volcanic rocks and Early Palaeozoic granites in the same area have demonstrated that the Early Carboniferous granodiorites have the same geochemical characteristics as volcanic arc granites (VAGs), thus indicating that the northward subduction of the Hegenshan Ocean may have continued through the Early Carboniferous. The monzogranite and alkali feldspar granites, in conjunction with the Late Carboniferous lagged arc volcanic rocks observed in this area, suggest a syn‐collisional to post‐collisional setting. The new data presented in this study provide constraints on the timing of the transition from island‐arc magmatism to post‐collisional extension‐related magmatism in this region during the later stage of the Early Carboniferous.

Zircon U–Pb age, geochemistry and Sr‐Nd‐Hf isotopes of the Baolige granite complex in the Great Hingan Range, NE China

et al. 2017

The Solonker zone is widely accepted as the suture between the North China Craton and the Siberia–Mongolia continental plate. The Baolige granite complex is located to the north side of the Solonker Suture and is mainly composed of monzogranite and granite. Zircon U–Pb ages, geochemistry, and Sr‐Nd‐Hf isotopic data of the Baolige granites were presented to constrain their petrogenesis and tectonic settings. Two monzogranite samples from Baolige yielded weighted mean zircon 206Pb/238U ages of 310.7 ± 2.1 Ma (mean square of weighted deviates (MSWD) = 1.3) and 307.4 ± 1.6 Ma (MSWD = 0.77), whereas the granite intruded into the monzogranite yielded an age of 296.2 ± 2.0 Ma (MSWD = 1.2). Both the Baolige monzogranite and granite contain high contents of SiO2, K2O, and Al2O3, low contents of TiO2, MgO, and CaO, and are peraluminous high‐K calc‐alkaline. These rocks are characterized by enrichments of K, Rb, U, Pb, Th, and light rare earth elements and depletions of Nb, Ta, Ti, and heavy rare earth elements and contain slightly negative or no Eu anomalies, similar to typical arc‐related granitoids. The Ti‐in‐zircon thermometry yielded 650–759 °C for the monzogranite and 645–796 °C for the granite. The monzogranite shows positive zircon εHf(t) values (4.7–13.2) and whole‐rock εNd(t) values (3.6–5.2), with TDM2(Hf) ages of 1,324–557 Ma and TDM2(Nd) ages of 1,015–821 Ma, and ISr of 0.70363–0.70386. The granite shows εHf(t) values of 15.6–20.9 and εNd(t) values of 4.0–5.1, with TDM2(Nd) ages of 957–832 Ma, and ISr of 0.70364–0.70406. Geochemical evidence indicates that the Baolige granite complex is highly fractionated I‐type and was likely formed by partial melting of the Neoproterozoic juvenile crust in a continental arc setting. We concluded that the Paleo‐Asian Ocean may have undergone north‐dipping subduction beneath the Siberia–Mongolia continental plate during the Late Carboniferous, and the subduction may have continued to the Early Permian (ca. 296 Ma).

Geochronology and geochemistry of the Late Jurassic bimodal volcanic rocks from Hailisen area, central‐southern Great Xing'an Range, Northeast China

Zircon U–Pb dating and whole‐rock geochemical analysis have been studied on the Late Jurassic volcanic rocks in the Hailisen area, Northeastern China, with the aim of constraining the tectonic evolution of the central‐southern Great Xing'an Range during the Late Jurassic. The volcanic rocks mainly consist of andesite from the Tamulangou Formation, and rhyolite and minor dacite from the Manketouebo Formation. The results of inductively coupled plasma‐mass spectrometry Zircon U–Pb dating for two andesites and one dacite indicate that they formed in the Late Jurassic (161–150 Ma). The mafic rocks are characteristic of low TiO2 (1.01–1.04 wt.%) and P2O5 (0.23–0.31 wt.%) contents, and high Al2O3 (17.19–20.18 wt.%) and CaO (6.69–7.45 wt.%) contents, and belong to the low‐K tholeiitic series. These mafic rocks are also characterized by moderately enriched light rare earth element (LREE) patterns and high abundances of Th, U, Zr, and Hf but negative Nb, Ta, and Ti anomalies. The felsic rocks are enriched in alkalis, Th, U, and LREEs; depleted in Ba, Sr, Nb, Ta, and Ti; and exhibit moderately LREE‐enriched patterns. These features indicate that the mafic volcanic rocks were likely formed by the partial melting of a lithospheric mantle that was metasomatized by subduction‐derived components, but the felsic rocks could derived by partial melting of a crustal source. The Tamulangou and Manketouebo formations have compositions of typical bimodal volcanism, an extensional environment, similar to a post‐orogenic setting, which might be related to the closure of Mongol–Okhotsk Ocean.
