Summary: Understanding the kelyphites around garnets in mantle peridotite xenoliths is crucial for studying tectonic evolution and mantle transformation. Detailed analysis of the texture and mineral compositions of garnets and their kelyphites reveals primitive and metasomatic types. The primitive kelyphites consist of two concentric coronae, while the metasomatic kelyphites were formed by late metasomatism of the primitive kelyphites. Overall, this study provides important insights into the mantle processes beneath the Xing'an-Mongolia Orogenic Belt.

Summary: Determining the physical and chemical structures of the inaccessible continental lithosphere through comprehensive geophysical and geochemical studies can yield valuable information on its formation and evolution. An integrated study on the lithospheric mantle structure of the North China Craton (NCC) using various methods reveals a relatively heterogeneous lithospheric mantle with preferential modification in the eastern NCC and peripheral regions of the western NCC, while the interior of the craton remains stable.

Summary: Elevated contents of structurally-bound hydrogen in olivine can decrease the effective viscosity and make it susceptible to basal erosion. However, there are large variations in hydrogen contents of mantle olivines from different cratons, and the role of water as the main driver of rheological weakening is contentious.

Summary: This study investigates the role of sulfate as a vector for the mobilization of oxidized components in the subduction zones, based on the examination of orogenic spinel and garnet peridotite lenses from the Ulten Zone in the Eastern Alps of Italy. The research reveals the influence of multiple C-O-H-S-bearing fluids and melts on the peridotites during their metamorphic evolution. The findings suggest limited interaction with isotopically heavy crustal fluids and indicate a subordinate role of subduction-derived sulfate in the extended fluid/rock evolution of the Ulten Zone peridotites.

Summary: The mantle lithosphere beneath the North China Craton underwent significant transformations from the Paleozoic to the Cenozoic, with changes in thickness, composition, and isotopic signature. The destruction of the craton was influenced by Paleozoic subductions and Mesozoic dynamic processes like mechanical intrusion, melt fluid erosion, and local delamination, leading to lithospheric thinning and extension.

Summary: This study provides insights into the nature and evolution of the lithospheric mantle beneath the Siziwangqi region through petrological observations and in situ analysis of peridotites. The high-Mg# peridotites are remnants of Archean-Paleoproterozoic refractory lithospheric mantle, while the low-Mg# peridotites are likely reaction products of high-Mg# peridotites and asthenospheric melts. Both high and low-Mg# peridotites show evidence of multi-stage refertilization by asthenospheric melts.

Summary: This study presents data on lithospheric mantle xenoliths from two alkali basalts in south-central Vietnam, Pleiku and Xuan Loc, revealing the heterogeneity and metasomatic processes that have occurred in the Indochinese subcontinental lithospheric mantle (SCLM). The xenoliths display fertile and refractory compositions, along with variable isotopic signatures, suggesting variable melt extraction and recent asthenospheric melting. The study also suggests that large-scale delamination is not necessary to explain the observed characteristics, and the SCLM has been modified by melt infiltration.

Summary: The study suggests that the high content of orthopyroxene in the Kaapvaal craton may have been caused by early high-degree melting leading to depletion, followed by interaction with Si-rich melts, resulting in the formation of Opx-rich rocks. Such xenoliths are consistent with the experimental results, supporting a two-stage model of 'metasomatism-depletion'.

Summary: The study of peridotite xenoliths from the Chidliak kimberlite province on southern Baffin Island provides insights into the age of the mantle lithosphere beneath the eastern Hall Peninsula Block. The findings suggest an ancient melt depletion event around 2.8 billion years ago influenced the formation of the Chidliak lithosphere, aligning with the main crust-building ages of the region. Additionally, similarities in metasomatic history indicate a connection between the mantle lithosphere of the EHPB and the Greenlandic portion of the North Atlantic Craton.

Summary: Research reveals that the underlying mantle in Southern Victoria Land, Antarctica preserves evidence for major mid-Proterozoic lithosphere formation, despite the dominance of late Neoproterozoic to Ordovician rocks in the crust. The heterogeneous mid-Proterozoic mantle in the region has persisted on a Ga timescale, possibly due to the thick East Antarctic Craton lithosphere shielding the adjacent mantle from convective asthenosphere-driven erosion.

Summary: The formation of cratons during the mid-Archean to mid-Proterozoic period was favored, resulting in stable crustal shields with thick and cold mantle roots. These cratons have remained stable over time due to the high viscosity of the cratonic mantle, possibly influenced by dehydration during the formation process. Grain size may play a more significant role in controlling cratonic strength than the hydrogen content. The cratonic mantle, despite being wet and metasomatized, has achieved strength through the coarsening of grains and the passage of fluids.

Summary: This paper presents data on garnets from serpentinized peridotite xenoliths in the Nyurba and Botuoba kimberlite pipes of the Nakyn kimberlite field. The garnets are divided into two types with different REE distribution patterns, indicating two types of metasomatic agents. The geochemical characteristics of the garnets suggest a moderate reworking of lithospheric peridotites by silicate melts.

Summary: The study shows that water content decreases with depth in the southwestern Kaapvaal Craton, broadly matching the distribution of metasomatism. While most water content measurements from xenolith samples agree with the models, discrepancies suggest a local metasomatic control over xenolith water contents.

Summary: Two clinopyroxene megacrysts, DMP-2 and DMP-3, from Cenozoic alkali basalts in Hannuoba region of China were characterized for major and trace element compositions through in situ microanalysis. Both clinopyroxene samples showed homogeneity in element mass fractions based on EPMA and LA-ICP-MS analyses. Bulk analyses using XRF, ICP-OES and solution ICP-MS techniques also revealed consistent major and trace element data. Thus, these samples can serve as potential reference materials for elemental in situ microanalysis, with recommended element mass fractions for thirty-two elements.

Summary: Contrary to previous understanding, research on typical zircon samples from gneisses and intrusive leucogranites in the Suhum Basin in SE Ghana suggests that Neoarchean crustal material was involved in the formation of the Palaeoproterozoic juvenile crust of the Birimian terranes in Ghana. U-Pb dating and Lu-Hf isotopic analysis of the zircons indicate that crust-forming events occurred within the Suhum Basin over a time interval of 139 Ma, from 2224 to 2085 Ma, during different contemporaneous magmatic episodes. Whole-rock Lu-Hf data for the gneissic and leucogranitic rocks show model ages (T-DM2) ranging from 2789 to 2456 Ma with eHf(t) values ranging from -1.1 to +5.4, suggesting that the magmas that formed these rocks originated from the early Palaeoproterozoic juvenile mantle with significant reworking of Neoarchean crustal material.

Summary: The Jehol and Yanliao biotas of northern China, two world-class Lagerstatten, have provided important clues to the Mesozoic terrestrial ecosystems. The evolution of these biotas in response to the destruction of the North China craton remains a mystery. However, statistical analyses show a coevolutionary relationship between volcanism and the proliferation of terrestrial biotas, where volcanic nutrient element delivery, biomass, and biodiversity increase synchronously while harmful elements decrease. This suggests that the voluminous volcanic products produced under the geodynamic regime of paleo-Pacific subduction and cratonic destruction created a conducive environment for the high prosperity of Mesozoic terrestrial biotas.

Summary: Fractional crystallization of Fe-Ti oxides during late-stage basalt differentiation can lead to detectable changes in Mg isotopes. The effect of chromite crystallization on Mg isotopic fractionation during early-stage basalt differentiation is poorly understood. This study examines the possibility of chromite-induced Mg isotope fractionation by analyzing chromite-olivine pairs in different types of basaltic intrusive rock suites formed by fractional crystallization. The results suggest that early crystallization of chromite can cause equilibrium Mg isotopic fractionation with olivine.

Summary: The Mesozoic terrestrial Jehol Biota of northern China is more diverse and has a larger biomass than contemporaneous Lagerstatten. The increase in phosphorus delivery, biological productivity, and species abundance in the middle-late Mesozoic volcanic-sedimentary sequences of northern China reveals the coevolution of volcanism and terrestrial biotas. The supply of phosphorus from the weathering of volcanic products of the destruction of the North China Craton supported a terrestrial environment conducive to the high prosperity of the Jehol Biota.

Summary: The traditional interpretation of mantle peridotites in ophiolites needs to be reconsidered as recent petrological and geochemical data suggest significant compositional variations and modifications in these rocks. The presence of interstitial spinel grains and widespread clinopyroxene suggests post-crystallization modifications. Amphibole and enriched Mg and Ca melts/fluids serve as evidence of the past presence of hydrous melts and indicate interactions between different lithologies. The mantle peridotites of ophiolites cannot be considered as paleo-oceanic lithospheric mantle and cannot be used for reconstructing ancient oceans or constraining global tectonic processes.

Summary: Granitoids, a major component of the Earth's crust, exhibit significant variations in K isotopic composition. This study examined a suite of well-characterized crustal igneous rocks from the Tagong pluton and found a positive correlation between delta K-41 values and SiO2 and K2O contents, and a negative correlation with MgO and Al2O3 contents. Fractional crystallization of K-rich phases and the presence of mafic microgranular enclaves were identified as key factors contributing to K isotope heterogeneity in the crust.

Summary: This article reports the formation of Cr-bearing spinel through the interaction between alkali basaltic magma and fertile lherzolite. It is similar to the occurrence of concordant podiform chromitites in ophiolites and stratiform chromitites in layered intrusions. The significant difference is that the Cr-bearing spinel formed from the alkali basaltic melt-lherzolite interaction is extremely rich in Al.

Summary: Potassium (K) is an essential electrolyte that plays a crucial role in cellular functions. This study investigates the natural distribution of stable K isotopes in different organs and red blood cells (RBCs) in mice and their potential use as biomarkers for diseases related to K+ homeostasis. The results show that different organs and RBCs have distinct K isotopic signatures, with RBCs showing heavy K isotopes enrichment and brains showing lighter compositions compared to livers and kidneys. The study suggests that K isotopic composition could be used as a biomarker for changes in K+ homeostasis and related diseases.
