The Permian Fengcheng Formation in the Mahu sag of the Junggar Basin is a crude oil reservoir and source rock. However, its stratigraphic characteristics, the boundary marks of the three members (lower, middle, and upper), and the sediment-filling processes are unclear. This study presents the sedimentary systems and sediment-filling processes in an intracontinental rift basin of this area using sedimentary-faces analysis, sequence stratigraphy, well logs, and two-dimensional seismic interpretations. The results show that the Fengcheng Formation consists of three third-order sequence stratigraphy (SQf1, SQf2, and SQf3). The lowest member of the Fengcheng Formation is composed of gray to dark gray thin middle layers of tuff, lacustrine dolomitic mudstone, and argillaceous dolomite near the depocenter. Tuff, siltstone, a small amount of fan–delta glutenite, volcanic breccia, and basalt are present near the fault zone. The logging curve is characterized by a high gamma-ray (GR) value, high amplitude, wavelength growth, and medium frequency. Near the depocenter, the middle member of the Fengcheng Formation comprises gray and gray–black thin layers of lacustrine muddy dolomite and dolomitic mudstone and thin sandstone and mudstone interbedded between tuff and gravel near the orogenic belt. The logging curve displays high-to-low GR values, high amplitude, short wavelength, and high frequency. The upper member of the Fengcheng Formation is not characterized by lesser tuffaceous and dolomitic components but by an increased fan–delta sandy content. Next, the bottom of the upper member is composed of lacustrine mudstone and siltstone interbedded between dolomitic mudstones; whereas, the top of the upper member is dominated by fan–delta coarse sandstone and sandy conglomerate. The logging curve shows low GR values, small amplitude, and continuous stability. The sediment-filling process of the Fengcheng Formation is controlled by fault activity. Overall, the lower and middle members of the Fengcheng Formation expand during the sediment-filling process of the lake basin of the Mahu sag; whereas, the upper member contracts. The strong uplift of the Horst near the Baiquan and Mahu orogenic belts led to an increase in provenance supply, resulting in a contraction of the southwestern margin of the lake basin during the sedimentation period from lower member to upper member of Fengcheng Formation.

AbstractThis paper presents new zircon U–Pb geochronological, Hf isotopic and whole‐rock geochemical data for the granitic plutons in the Xing'an Massif, Northeast China, to constrain the Late Mesozoic tectonic evolution of the Mongol‐Okhotsk Ocean and the Paleo‐Pacific Ocean. The zircon U–Pb ages indicate that the granitoids emplaced during the Late Jurassic–Early Cretaceous. The granodiorites show an adakitic affinity with high Sr/Y ratios and low Yb (< 1.30 μg/g) contents. The monzogranites exhibit high SiO2, low MgO contents, enrichment in LILEs (Rb, K, and Th), and depletion in HSFEs (Ta, Nb, Zr, P, and Ti). Petrological and geochemical features of these monzogranites suggest that they are highly fractionated I‐type granitoids. In addition, the zircon εHf(t) values and two‐stage model ages (TDM2) are in the range of +2.6 to +8.1 and 669–1011 Ma, respectively, indicating that primary magma was generated by partial melting of juvenile lower‐crustal materials, and there was a significant crustal growth in the Phanerozoic in the Northeast China. Combined with the coeval granitoids widely exposed in the Xing'an Massif, we conclude that the Late Jurassic magma in Northeast China was generated in an extensional setting related to the closure of the Mongol‐Okhotsk Ocean, but the Early Cretaceous magma was related to the subduction of the Paleo‐Pacific Plate.

A database of 1075 high-precision geochemical analyses of least-altered ultramafic–mafic units, predominantly flows, was compiled for the Eastern Goldfields Superterrane. Samples are divided into a high-Mg population at MgO≥10–24 wt% and a basaltic population where 4≤MgO<10 wt%. There are eight groups based on (La/Sm)N and Nb/Th ratios. Five magma series are identified. Uncontaminated komatiitic basalts have MgO ∼11–23 wt% and Nb/Th≥8, whereas contaminated counterparts have Nb/Th<8 corresponding to silicious high-Mg basalts (SHMB). A distinct second magma series with MgO ∼5–18 wt% MgO has a narrow range of Nb/Th at 0.5–≤2 over a range of (La/Sm)N from 0.7–5.5, unlike contaminated suites where (La/Sm)N and Nb/Th are correlated; this series corresponds to the enriched Paringa Basalt representing shallow melts of heterogeneous domains of the plume with recycled ancient continental lithosphere, or an independent plume. Prevalent, crustally uncontaminated, tholeiitic basalt magma series three all have Nb/Th≥8, span Mg-rich to fractionated Fe-rich counterparts, and range from LREE-depleted to mildly LREE-enriched where high Nb/Th ratios stem from eclogite streaks in the asthenosphere plume; contaminated equivalents have Nb/Th<8. A fourth alkaline, high-Mg magma series has a narrow range of MgO at ∼13–16 wt%, extends to elevated TiO2 and Ni contents relative to komatiitic basalts at that MgO range, and features (La/Sm)N ≥2. Two additional uncontaminated tholeiitic basaltic groups are defined respectively by high-Nb to 20 ppm akin to alkaline ocean island basalts, and high-ΣREE relative to the other basaltic groups. The former, a fifth magma series, reflect melts of an eclogite-rich domain of the plume. Contamination of all groups, when present, was dominantly by interaction with continental mantle lithosphere with a minor crustal component. Komatiitic basalts are fractionation products of komatiites erupted from the hot axis of a mantle plume whereas prevalent tholeitic basalts are liquids derived from the cooler plume annulus. In all cases melting was in anhydrous peridotite. Ratios of Nb/Th in uncontaminated samples span 8–24 signifying that the Neoarchean mantle was as heterogeneous in terms of this ratio as Phanerozoic asthenosphere. In contrast, the fourth alkaline magma series stems from decompressional melting of metasomatised, hydrous, continental mantle lithosphere at >90km. Komatiites and komatiitic basalts are most abundant proximal to terrane boundaries because mantle plumes are ‘steered’ to the margins of thin, rifted, continental lithosphere. Given that mantle plumes melt on impingement at the base of the lithosphere, (Gd/Yb)N ratios are used as a proxy to ‘map’ the thickness of the contemporaneous lithosphere.
