Summary: Selective crystallization can achieve high chromium recovery for sustainable recycling of Cr-containing stainless steel slags by controlling thermophysical properties based on crystallization kinetics. In this study, in-situ observation and crystallization kinetics of synthesized Cr-containing slags were investigated using confocal laser scanning microscopy and differential scanning calorimetry. The crystallization characteristics of the CaO-SiO2-Al2O3-MgO-Cr2O3 slag system were analyzed, and the growth mechanism of primary spinel phase and crystallization kinetics of calcium silicate phase were demonstrated. The apparent activation energy during non-isothermal crystallization was determined using the Friedman differential isoconversional method.

Summary: Volcanism is the surface expression of extensive magmatic systems, with the majority of magma being intruded deep within the Earth. In continental or oceanic environments, intrusive igneous rocks often exhibit geochemical cumulate signatures, which can be explained by mineral-melt segregation. Deformation-assisted compaction and melt buoyancy are commonly thought to be the main processes involved in melt extraction, but recent studies suggest the involvement of other processes, such as melt-mush reactions.

Summary: Chromite-rich rocks and monomineralic chromitites in mafic-ultramafic layered intrusions are economically important as they contain significant resources of chromium and platinum group elements. This study focuses on chromite-hosted multiphase inclusions in the Noril'sk-1 intrusion, which provide direct insights into the process of bulk chromite crystallization during hybridization of magma. The findings suggest that assimilation-driven formation of chromite-rich lithologies in intrusions requires sufficient Cr contents in the magma, efficient digestion of host rocks, and a mechanism for accumulating excess chromite within a small volume.

Summary: By using the concept of surface lattice-matched engineering, a spinel coating P2/P3 heterostructure cathode material is designed with enhanced air stability, rate, and cycle performance. The surface spinel phase plays a vital role in preventing the ingress of water molecules, improving transport kinetics, and enhancing structural integrity for NaxTMO2 cathodes. The concept of surface lattice-matched engineering based on in situ spinel interfacial reconstruction will be helpful for designing new ultra-stable cathode materials for high-performance sodium-ion batteries.

Summary: The study focuses on the timing and petrogenesis of magmatic rocks in the Central Indian Tectonic zone (CITZ). Petrology, geochemistry and U-Pb in-situ zircon dating of porphyritic granitoids from the Makrohar Granulite Belt (MKGB) reveal that crystal fractionation is the dominant process in the evolution of the arc magma. The in-situ U-Pb zircon age of 1750 Ma suggests a southward progression of the arc front in the Indian shield during the growth of the Columbia supercontinent.

Summary: Studies indicate that the lower oceanic crust in the Atlantis Bank region contains an interlayered section of fine- and coarse-grained olivine gabbros, which record the reactive porous migration of magma. The area also shows occurrences of partial melt percolation and modifications in rock compositions, indicating that the composition of crustal lithologies is strongly influenced by the type of magma migration and modalities of melt percolation.

Summary: This study investigates the selective removal of sulfate (SO42-) from wastewater by co-precipitation to form hydrotalcite. Optimal conditions and methods are determined, and it is found that sulfate can be more easily removed than chloride. A first-principles approach is used to analyze the selective intercalation process. The formed coprecipitation products also show excellent adsorption properties for heavy metals. This research provides a simple and economical method for converting polluted wastewater into valuable products.

Summary: The direct synthesis of LDHs in wastewater and its removal mechanism were investigated in this study. Two different paths, A-S process and S-A process, were proposed. In the A-S process, the formation of LDHs involved three stages, with the removal of Cr(VI)/As(V) increasing significantly upon the formation of LDHs structure. In the S-A process, the formation of LDHs primarily involved structure optimization, accompanied by the removal of Cr(VI)/As(V).

Summary: In this study, the authors collected samples from the Bijigou intrusion and analyzed the crystal size distributions and major and trace elements of magnetite and ilmenite. They found that the crystallization of Fe-Ti oxides can be distinguished by their crystal size distributions, and in situ crystallization is likely triggered by increasing oxygen fugacity due to water decomposition. The study also showed that analysis of crystal size distributions for Fe-Ti oxides is applicable to examine the accumulation mechanism of Fe-Ti oxide ore bodies in layered intrusions.

Summary: The Huangyangshan super-large graphite deposit in Xinjiang Province is closely related to the Huangyangshan alkaline granites in terms of time, space, and origin. The graphite-bearing granites contain silicate minerals such as amphibole, biotite, pyroxene, and plagioclase. By analyzing the samples, the physicochemical conditions and evolution process of the alkaline magmatism and graphite mineralization were revealed. The study also showed the important influence of mixing of mafic mantle-derived magma and felsic crust-derived magma on the evolution and differentiation of the melts.

Summary: The Panzhihua gabbroic layered intrusion in SW China is a giant magmatic Fe-Ti-(V) oxide deposit. This study investigates the accumulation mechanism of Fe-Ti oxides in the lower and middle zones of the intrusion through the analysis of crystal size distributions and composition of clinopyroxene, as well as the three-dimensional morphology of Fe-Ti oxides. The results suggest that the Fe-Ti oxides may have crystallized from an interstitial Fe-rich melt within the crystal mush, forming the Fe-Ti oxide ore layers in the Panzhihua intrusion.

Summary: Geological and tectonic analysis of the Eastern Himalayan basins have sparked a decade-long debate on the geodynamic evolution of the Burmese terrane and the reorganization of the main SE Asia drainage systems. This study focused on the Central Myanmar Basin (CMB) and analyzed detrital grains to determine provenance, depositional ages, and environments. The results shed light on the transport pathways of Himalayan detritus in the CMB and provide insights into the geodynamic evolution of the region, revealing new sources contributing to the basin during the Oligocene.

Summary: This study combines new Pb isotopic analyses of detrital K-feldspar with published data to determine the dominant source of sediment in the Yangtze River; it reveals that southeastern Tibetan tributaries are the main contributors. K-feldspar from middle-lower reaches tributaries are not well represented in the trunk Yangtze, indicating a minor contribution. The study suggests that tectonic uplift in southeastern Tibet plays a key role in sand supply.

Summary: By analyzing sediment samples from the western Jianghan Basin and the Neogene Yangtze Gravel, this paper determines that the Three Gorges was formed after the late Miocene but before the late Pliocene. The detrital zircon source signal has been homogenized through transportation and recycling processes in the Yangtze Craton, showing a signature indistinguishable from that of the modern Yangtze River.

Summary: The unique drainage pattern in the southeastern Tibetan Plateau is not a result of the breakup of a single paleo-Red River system. Evidence suggests that during the Eocene, there was a river flowing through the Jianchuan Basin from the Qiangtang Block and Songpan-Ganzi, while the modern Red River is not a major ancient river in the region.

Summary: The study demonstrates the use of U-Pb dating of sedimentary apatite to understand early diagenesis and reworking in ancient rocks. The deposition of phosphate-rich sedimentary rocks is linked to significant environmental flux and geological events, providing valuable insights into Earth's evolutionary history and paleoenvironmental conditions. The integration of phosphate U-Pb dating and trace element analysis could offer age constraints for key geological periods, aiding in the reconstruction of evolutionary and paleoenvironmental records.

Summary: The origin and development of major rivers in the eastern Tibetan Plateau are closely related to river formation, tectonic uplift, and climate change. This article reviews sedimentary provenance investigations of rivers in eastern Tibet, including the Mekong, Red, Pearl, Yangtze, and Yellow rivers, to understand their evolution. The timing of river formations varies, with the Mekong River forming around -17 Ma, the Pearl River in the late Oligocene, and the Yangtze River still under debate. The evolution of these rivers is influenced by climate and tectonics, highlighting their importance in controlling river evolution.

Summary: Using Pb isotopes in detrital K-feldspar, we address the debated initiation time of the Pearl River. The Eocene and Early Oligocene sandstones in the northern South China Sea were supplied by proximal rivers draining the Cathaysia Block, while the Late Oligocene and Miocene sandstones mainly originated from the western Pearl tributaries. Detrital zircon data from the Beibuwan Basin suggest that the western tributaries flowed into this basin before being captured by the paleo-Pearl River, indicating a progressive headward erosion and late Oligocene integration of the Pearl River.
