Abstract Magmatic processes associated with oceanic crustal accretion at slow-spreading mid-oceanic ridges are less well understood compared those fast-spreading ridges. Zoned plagioclase in the basalts might record these magmatic as a result of very slow intra-crystal diffusion CaAl–NaSi. Plagioclase phenocrysts plagioclase-phyric basalt from Hole U1433B International Ocean Discovery Program (IODP) Expedition 349 South China Sea show complex zoning patterns (e.g. normal, reverse,...
Abstract Controversies remain as to the Permian tectonic setting in Central Asian Orogenic Belt (CAOB), particular, regarding triggering of magmatism. To address this issue, we carried out a geochemical study on Dananhu volcanics from Tuha basin, southwestern CAOB. 40 Ar/ 39 Ar analyses for feldspar separates yield Carboniferous age 321.2 ± 9.8 Ma andesites and 278.9 4.2 basalts. Both basalts geochemically resemble subduction‐related magmas aspects their trace element Sr‐Nd‐Pb isotopic...
Abstract Whole-rock geochemistry, usually changed by magmatic processes, might provide misleading information on the petrogenesis of adakites. The Heishantou porphyritic diorites in Nileke, Western Tianshan orogenic belt record complex magma chamber such as replenishment, fractional crystallization and crustal contamination, thus, ideal samples for tracing processes that generate typically high Sr La contents Sr/Y La/Yb ratios In situ clinopyroxene amphibole compositions (271 ± 2 Ma) are...
Abstract Plate reconstructions reveal that two secular centers of convergence formed beneath eastern Eurasia and North America no later than 200 Ma. The cause these centers, which featured flat subduction, slab stagnation, and/or continental margin remains uncertain. Here, we propose upper-mantle thermal inhomogeneity, particularly an anomalously cool Northern Hemispheric upper mantle, was a fundamental driver this long-lived convergence. By considering the pattern observed our numerical...
Abstract Additional subsidence of oceanic basins compared to the half-space cooling prediction is thought be a dynamic response underlying mantle convection induced by slab sinking. Here, we identified significantly elevated proportion (10%–20%) recycled crust (ROC) in source mid-ocean-ridge basalts (MORBs) from South China Sea (SCS), illustrating ROC accumulation within confined upper-mantle range, possibly as result long-term surrounding subduction events. The presence this lithological...
Rapid determination of the original boron composition from altered basaltic glass by SIMS isotopic profile analysis core to rim.
In this study, we developed a method for measuring Sm–Nd isotopic ratios in samples with low Nd contents (<100 μg g −1 ) by LA-MC-ICP-MS.
The discovery of Carboniferous hydrocarbon source rocks in the Mahu-Shawan Sag has implied considerable exploration potential strata western Junggar Basin. However, controversy long surrounded when and how Ocean was eventually closed, leading to a poor understanding basin evolution continental growth Central Asian Orogenic Belt. We performed stratigraphic geochronologic studies establish chronostratigraphic framework Basin better understand its tectonic-sedimentary during Carboniferous-Early...
The development of the Fourth Industrial Revolution heavily relies on green and renewable new energy. In response to climate change energy security, Chinese government has formulated strategic goals for carbon neutrality emission peak. Rare earth elements play a crucial role as functional modifiers in various stages industry. This article analyzes application scenarios demands rare their materials fields such wind power, hydropower, storage, catalysis. It introduces layout progress China...

Abstract Understanding the petrogenesis of alkaline syenites is important for constraining mechanisms rare earth element (REE) and rare-metal mineralization. Here we report a detailed petrological geochemical study early Permian syenitic rocks from southwestern Tarim large igneous province (TLIP) in Wajilitag area (China). We use these data to investigate complex magmatic processes responsible enrichment incompatible elements (e.g. REEs metals) rocks. The comprise hornblende syenite (281 Ma)...
