Although the pullout capacity of plate anchors in clay has been studied extensively, results considering coupling effects anchor inclination, non-homogeneity and self-weight are relatively rare. In present paper, finite-element analyses carried out to investigate these factors on strip clay. The numerical solutions presented familiar form based various embedment depth, strength profile self weight, also compared with existing empirical solutions. A design procedure data-fitting equations is...
Frequent natural fracturing along shale bedding interfaces facilitates the formation of bed-parallel fractures. However, these mechanisms are not yet fully understood. The middle Permian Lucaogou Formation in Jimusar Sag Junggar Basin serves as a quintessential example fractured shale. Complex geological processes have led to development numerous fractures, which significantly contribute formation’s heterogeneity. In this study, we analyzed rare earth element, fluid inclusion, and C-O-Nd...
Identification of juvenile and mature crustal sources in granite formation relies on radiogenic isotopic systems such as Sm-Nd Lu-Hf assumes isotope reach equilibrium between the melt residual phases prior to extraction.However, we hypothesise disequilibrium melting zircon result preferential retention 177 Hf residues, generating partial melts with higher 176 Hf/ ratios.To test this hypothesis, evaluate signatures strongly-peraluminous granites from Chinese Altai.These show Nd-Hf decoupling...
Late Cambrian to Devonian granitic magmatism in the Chinese Altai provides a critical view of geodynamic processes active during crustal growth Central Asian orogenic belt. In this study, we report results zircon U-Pb and Hf-O isotopic compositions, whole-rock geochemical signatures, Nd data for late Cambrian–Early granites Altai. These were emplaced between 497 397 Ma have high SiO2 (66.02–72.07 wt%) K2O (3.18–5.19 contents, low Fe2O3t (1.94–5.63 wt%), MgO (0.21–2.23 CaO (0.62–1.25 with...
This study investigates three Lopingian (upper Permian)-Lower Triassic terrestrial successions in northwest China, namely the Urumqi and Jimsar sections southern Junggar Basin (SJB), Taodonggou section Turpan (TB). Stratigraphy studies suggest that, all sections, Lopingian-Lower strata are represented by mixed fluvial lacustrine deposits. The lithofacies geochemical indicators (CIA, PIA) Wutonggou Formation (Wuchiapingian) was deposited under subhumid conditions. Guodikeng...
Abstract Late Carboniferous magmatism in the Chinese Altai provides an important view of geodynamic processes active during crustal growth Central Asian Orogenic Belt (CAOB). In this study, five representative peraluminous granite plutons from were selected for systematic geochronological, geochemical and Sr–Nd–Hf isotopic analyses (Table 1). These granites emplaced between 449 327 Ma subduction zone, have moderate to high SiO 2 (66.54–76.13 wt%), Na O+K O (6.27–7.66 Al 3 contents...
The Middle–Upper Jurassic Shishugou Group in the central Junggar Basin was deposited a lacustrine shallow-water delta-meandering river sedimentary system. integrated petrological (thin-section, granularity and heavy minerals analysis), geochemical (trace elements rare earth analysis) geophysical analyses (well logging 3D-seismic slice are used to determine redox conditions, paleoclimate, paleosalinity, provenance evolution extant during deposition of Group: (1) condition changed from weak...
Abstract The gas content in shale reservoirs is often determined by the micro storage and sealing capacities of reservoir. Deep are high- or over-thermale maturity stage have complex pore structure connectivity, which highly heterogeneous vertical distribution. Research on gas-bearing property deep limited these microscopic conditions. To analyze characteristics reservoirs, this work collected summarized data total organic carbon content, mineral composition, porosity, water saturation,...
Wastewater treatment plants (WWTPs) are one of the largest sources energy consumption and greenhouse gas (GHG) emissions in urban systems. WWTPs account for 3% global electricity 2% GHG (in terms CO2 equivalents). Chinese wastewater emission standards have risen to improve water quality. The upgrading increased investments facilities, power chemical usage, others that can directly or indirectly increase carbon emissions. This study collected operational data from 15 key control areas Ziya...
Machine learning models must continuously self-adjust themselves for novel data distribution in the open world. As predominant principle, entropy minimization (EM) has been proven to be a simple yet effective cornerstone existing test-time adaption (TTA) methods. While unfortunately its fatal limitation (i.e., overconfidence) tends result model collapse. For this issue, we propose Conservatively Minimize Entropy (COME), which is drop-in replacement of traditional EM elegantly address...
The Longmaxi and Niutitang Formations are typical shale reservoirs in southeastern Chongqing. Since the Paleozoic, Chongqing has experienced multistage tectonic movement diagenesis, resulting formation of a large number natural fractures. In reservoirs, fractures not only provide seepage channels for oil gas migration but also play an important role reservoir space. Natural flow path from source rock to during filling connect hydraulic fractures, matrix pores, boreholes production....
