Abstract Aillikites are carbonate-rich ultramafic lamprophyres often associated with carbonatites. Despite their common field relationships, the petrogenetic links, if any, between aillikites and carbonatites remain controversial. To address this question, study reports results of a detailed geochemical isotopic examination Permian Wajilitag in northwestern Tarim large igneous province, including bulk-rock major- trace-element Sr–Nd isotope compositions, olivine (in situ secondary ion mass...
Abstract The origin of lamprophyres associated with large igneous provinces (LIPs) remains controversial, particularly whether they are derived by direct melting mantle plumes, or from previously metasomatized domains in thermally perturbed subcontinental lithosphere. Here, we report the petrological and geochemical characteristics a recently identified suite alkaline (sannaites) that represent final pulse magmatism Permian Tarim LIP NW China. sannaites display porphyritic texture...
Online learning democratizes and provides flexibility in accessing education, but it also places greater demands on students’ self-regulated strategies. Previous studies have explored the important impact of effort regulation academic performance. However, there remains more to explore dynamics among undergraduates their group differences. This study investigates how process varies between achievement categories an online environment using a sample 240 undergraduates. Findings suggest that...
Abstract Aillikites are carbonate-rich ultramafic lamprophyres, and although they volumetrically minor components of large igneous province (LIP), these rocks provide important clues to melting meta-somatism in the deep mantle domain during initial stages LIPs. In this study, we investigate Wajilitag “kimberlites” northwestern part Tarim LIP that redefine as hypabyssal aillikites based on following features: (1) micro-phenocrystic clinopyroxene Ti-rich andradite garnet occurring abundance...
Magnesium isotopes are widely used to trace recycled carbonates in the mantle source. We recently recognized extremely light Mg isotope values (δ26Mg = −0.50 −0.62‰) nepheline syenites Tarim large igneous province (TLIP), NW China. To evaluate significance of isotopes, we conducted petrological, mineral chemical, zircon U-Pb ages, and geochemical (Sr-Nd-Mg) analyses on syenite understand its petrogenesis. Laser ablation−inductively coupled plasma−mass spectrometry dating yields an age 272.5...
Recycled oceanic crust is believed to have played an important role in the formation of continental flood basalts, whereas involvement large amounts CO2 derived from recycled marine carbonate their mantle sources highly debated. Zn isotopes great potential trace due distinctly different δ66Zn values between carbonates and mantle. Representative basalt samples Keping (Group1) Yingmai Shengli (Group 2) Tarim, NW China, were collected investigate sources, studied systematically for first time....
Abstract The nature and source of magmatism associated with large igneous provinces (LIPs) remain disputed. Here we investigate the role recycled materials that contributed to mantle heterogeneity in Tarim Large Igneous Province (TLIP) China through integrated Zn–Mg–Sr–Nd isotopes a rare tephritic rock suite. Sr–Nd [(87Sr/86Sr)i = 0.70368–0.70629; εNd(t) −0.25–4.64] δ26Mg values (−0.23‰ −0.34‰) porphyries are consistent normal origin. In contrast, whole pyroxene phenocrysts...
Quartz is one of the most abundant minerals in shales, occurring predominantly three forms: biogenic quartz (BQ), detrital (DQ) and clay-transformed (CTQ). The content typically correlated with fracability shale gas reservoirs. However, origins its influence on mechanical properties remain not fully elucidated. To address this gap, study examines samples from LM1-LM8 graptolite zones well W202 Weiyuan field, Sichuan Basin as research object. After systematic analysis organic geochemistry,...
The Lower Cambrian Qiongzhusi formation and the Silurian Longmaxi Formation are two most important shale strata. Although differences between these shales have become focus of current research, a comparative study depositional environments has not been performed. Using cores both formations well W201, in situ comparison sedimentary environment was realized, interference other factors eliminated, which made results more reliable. In this study, 72 samples from were collected Weiyuan gas...
<title>Abstract</title> Transitional shale gas is an important area for oil and exploration. It has a wide distribution large resource potential, accounting about 25% of the total resources in China. The method reservoir fracture prediction by seismic attributes been relatively established. However, are often limited factors such as data frequency resolution. Characteristics transitional reservoirs, complex combinations lithologies, frequent lithological changes, low resolution changes...
The bimodal intermediate‐felsic suites are rare, and their petrogenesis remains unsolved. Here, we report a magmatic suite from East Junggar (NW China) composed of rhyolites, basaltic andesites, andesites. andesites porphyritic with phenocrysts predominantly plagioclase. rhyolites alkali‐feldspar, quartz, minor LA–ICP–MS zircon U–Pb dating yielded an age 284 ± 2 Ma for rhyolites. show SiO ranging 54.67 to 58.26 wt%, exhibit moderate TiO (1.45–1.77 wt%), K O (1.59–2.07 wt%) low MgO (1.51–2.25...
