“…The Permian Tarim Plume was considered to have extended to the western Tarim Table 1. Zhou et al, 2009;Xu et al, 2014) and may affect the Tianshan Orogen, which may explain the extensive Early Permian thermal anomalies and high-temperature A 2 -type granitoids and Cu-Ni-bearing maficultramafic intrusion in this region (e.g., Pirajno et al, 2008;Qin et al, 2011;Liu et al, 2013;Zhang and Zou, 2013).~300 Ma kimberlitic intrusions and Fe-Ti oxide-bearing mafic layered intrusion (He et al, 2016) in the southwest part of the Tianshan Orogen was attributed to the beginning of the Tarim Plume at the end of Carboniferous Xu et al, 2014;He et al, 2016). Devonian OIB-like mafic magmatism and ocean plate stratigraphy might even imply that the plume magmatism was active in the southern Tianshan Ocean in Devonian (Safonova et al, 2016).…”

“…Li et al 2011;Xu et al 2014). Based on 27 published dates, Xu et al (2014) proposed that the Permian Tarim magmatism comprises three main episodes: c. 300 Ma kimberlites, c. 290 Ma flood basalts and c. 280 Ma ultramafic-mafic-felsic intrusions and dyke swarms. The first episode is defined by three SIMS dates on perovskite and baddeleyite ), which we conclude here are not robust.…”

Abstract:The Permian Tarim magmatic province has 118 published ages, ranging from 358 to 205 Ma, but the timing of mafic magmatism is not well constrained. We report two new secondary ion mass spectrometry U-Pb zircon dates on the Halahatang trachydacite and Wajilitag olivine clinopyroxenite, which are 287.2 ± 2.0 Ma and 283.2 ± 2.0 Ma, respectively. The trachydacite overlies the uppermost basalt and constrains the latest eruption age of basalt in northern Tarim. The latter is the first high-resolution date for the Wajilitag mafic layered intrusion. By screening all published ages, we identified 22 robust ages, ranging from 290.9 ± 4.1 to 261.7 ± 1.8 Ma. The robust ages together with our new data reveal a protracted period of mafic magmatism at c. 283 and c. 267 Ma. Silicic magmatism occurred from 291 to 272 Ma. Although the current known volume of Tarim basalt is too small to qualify as a large igneous province, the eroded and intrusive components, as well as pyroclastic deposits and silicic lavas, may increase the estimated volume. Further work is required to refine the duration of magmatism and the volume estimate of the province.Supplementary material: A list of all the published dates, raw data of published 40 Ar-39 Ar dates, raw data of published U-Pb dates, published geochemistry data used for calculation and complete details of the data evaluation are available at

Abstract:In the Chernorud granulite zone in the Olkhon region of West Pribaikalie, we studied gabbro-pyroxenites composing tectonic plates (Chernorud, Tonta) and synmetamorphic intrusive bodies (Ulan-Khargana), as well as numerous disintegrated boudins and inclusions embedded in the metamorphic matrix. Based on the results of comparative analysis of the chemical compositions, the gabbro-pyroxenites are classified into a single island-arc tholeiitic series. The COMAGMAT software was used to simulate this series and to estimate the initial composition of the parent magma (magnesian basalt: SiO2=46.0 wt. %, TiO2=0.8 wt. %, Al2O3=15.3 wt. %, ΣFeO=9.0 wt. %, MnO=0.15 wt. %, MgO=10.5 wt. %, CaO=17.0 wt. %, Na2O=1.0 wt. %, K2O=0.2 wt. %, P2O5=0.05 wt. %, total = 100.0 %, Mg# = 67.5 %). It is concluded that the granulite metamorphism (P=7.7 to 8.6 kbar, T=770 to 820 °C) was due not only to dipping of the initial sedimentary-volcanic series to a depth of 25-28 km, but also to the presence of a deep chamber of magnesian basalt magma. In our estimations, garnet-pyroxenites (i.e. mafic rocks of the top facies in the above-mentioned chamber) originated at P=8.0-8.3 kbar and T=900-930 °C. Considering petrology, the deep mafic chamber under the layer of granulite facies is evidenced by metamorphic magma mingling, as well as pipe-shaped intrusions characterized by the specific morphology, internal structure and bulk rock compositions. Based on the data on the Ulan-Khargana massif and gabbro-pyroxenite bodies involved in the structure of the marble melange, we propose a petrological model showing two stages of mafic injection -Stage 1: hydraulic fracturing of granulite series and the emergence of tubular structures and bodies, which are similar to kimberlite pipes or channels of different shapes; Stage 2: rising of the fluidized residual alkaline melt through the emerging 'pipes' and fractures armored by hardened zones, which is followed by metamorphic magma mingling under viscous deformation conditions. The mafic magmas intruding to the
