Summary: Our research on the Trans-North China orogen has revealed the presence of a thick and refractory lithospheric mantle at approximately 1.54 Ga. This lithospheric mantle, which exhibits craton-like properties, may have been formed due to a large volume melt extraction caused by a major igneous event around 1.78 Ga. These findings are significant for understanding the evolution and stability of the Trans-North China orogen.

Summary: This study constrains the characteristics of zircon from mantle eclogite xenoliths through analyzing data from zircons in different geological settings, suggesting zircons within the xenoliths may have magmatic, metamorphic, and xenogenic origins. The origins of zircon in mantle eclogites can vary, including inheritance from mafic oceanic crust, direct crystallization from mantle-derived melts, and metasomatism related to kimberlite magmatism. The study also demonstrates a possible method for identifying inherited and xenogenic zircons within mantle eclogites, using zircon grains from kimberlite-hosted eclogite xenoliths.

Summary: The Singhbhum Craton of East India has a well-preserved Archaean geological record, including 3.5 to 3.3 billion-year-old greenstones and granites. While uncertainties remain, a consistent framework of craton evolution during the Archaean is proposed based on new data and literature review.

Summary: This study investigated the shock features of zircons on the lunar surface using transmission electron microscopy. Various shock-related structures and metamorphic phenomena were observed, but they showed no significant correlation with the ages of zircons. This suggests that the shock events either occurred after the formation of zircons or were too brief to cause noticeable lead loss during shock metamorphism.

Summary: The discovery of zircon xenocrysts provides insights into the evolution of the buried crustal basement in the West Ukukit kimberlite field, indicating significant tectonic events in ancient times played a crucial role in shaping the region. The multiple tectonomagmatic reactivations over different periods resulted in repeated eruptions of ore bodies in the West Ukukit kimberlite field, highlighting the complex and dynamic nature of deep Earth material cycling.

Summary: The study reveals that the mantle zircon megacrysts from northeastern Siberia have Triassic ages, typically formed from kimberlites or related alkaline mantle melts, and their compositions show significant variation in parental melt, potentially sourced from Triassic mantle. The chemically-heterogeneous sublithospheric source of these zircon megacrysts may have been formed through various mechanisms.

Summary: This study investigates the spatial and temporal changes in granitoid compositions in the Singhbhum Craton. The results indicate that the crust in Singhbhum Craton started building from a relatively thin oceanic plateau in the early Paleoproterozoic, and experienced gradual increase and decrease in thickness. These changes are related to the melting depth of the crust, resulting in changes in granitoid chemistry.

Summary: In this study, the chemical composition of 86 olivines from the Jericho kimberlite in Canada was analyzed, and three main olivine populations were identified. The results indicate a major change in the properties and composition of the kimberlite magma at the 150 km interface between the shallow and deep lithospheric mantle layers, likely due to assimilation of carbonate at this depth.

Summary: High-pressure experiments were conducted to study the behavior of argon in phlogopite under conditions corresponding to the mantle, providing insights into the dating methods for estimating mantle material age. The obtained data served as the basis for proposing a new behavior model of the K/Ar isotopic system for minerals in deep crustal conditions and during transport of xenoliths in kimberlite melt.

Summary: Through the study of whole-rock geochemistry, detrital zircon U-Pb-Hf isotopes, and trace element data from Mesoarchean clastic rocks in two greenstone belts of the western Dharwar Craton, it is found that these rocks were derived from a strongly weathered stable continental provenance dominated by low-HREE TTGs and K-rich granites of shallow crustal origin. The detrital zircon U-Pb and Lu-Hf data indicate two major crust formation events, with the antiquity of the western Dharwar Craton traced back to at least 3.8 Ga. The detrital record suggests episodic crustal growth and reworking in the western Dharwar Craton during the Paleoarchean to early Mesoarchean period, possibly related to intraplate processes.

Summary: Large volume rhyolitic ignimbrite volcanism significantly contributes to the evolution of the crust through the introduction of high-silica material and differentiation within the crust. Accurate models for the genetic evolution of these events rely on geochronology, which determines the rates of magmatic processes. This study presents new zircon geochronology and Hf isotope geochemistry for ignimbrites from the Mogollon-Datil volcanic field, providing insights into the protracted evolution of the lower crust.

Summary: A high spatial resolution LA-MC-ICP-MS calcite U-Pb dating technique was established by optimizing instrument parameters, and its effectiveness for analyzing low U content samples was confirmed. Two potential calcite U-Pb dating reference materials were preliminarily determined. The study also found that the change of laser spot size significantly affected the accuracy of the results, suggesting the need for strict matching of laser parameters between reference materials and unknown samples in calcite U-Pb dating.

Summary: This paper presents new data on water and trace element mass fractions and single-crystal structural refinement of the amphiboles from Kakanui and Arenal. The study reveals that the Kakanui amphiboles have better homogeneity compared to those from Arenal. The classification and nomenclature analysis further identifies the samples from Arenal as partially dehydrogenated pargasite and those from Kakanui as kaersutite. The significant presence of oxo-component and ordered Ti-C(4+) content suggest high fO(2) conditions during crystallization.

Summary: This study reports the uranium isotope ratios of twenty-nine geological reference materials, including various types of rocks and sediments. The measurements were done using a multi-collector inductively coupled plasma-mass spectrometer. The results show that most samples have U-234/238 values close to secular equilibrium, with minor fluctuations observed in Pleistocene speleothem samples. The U-238/235 values of igneous and metamorphic rocks are consistent with values found in the continental crust, while sedimentary rocks and sediments exhibit a wide range of values, indicating significant isotopic fractionation at low temperatures. The wider range of U-238/235 values reported in this study allows for inter-laboratory calibration of a broader range of geological and environmental samples.

Summary: Analysis of lunar soils returned by the Chang'e-5 mission suggests that impact glass beads on the Moon's surface may contain a significant amount of solar wind-derived water. This finding supports the existence of a hydrated layer in lunar soils that plays a role in the global water cycle on the Moon. The study also reveals that impact glass beads can serve as reservoirs for water on other airless bodies.

Summary: Porphyry Cu deposits are often associated with epithermal polymetallic (Ag-Pb-Zn-Au-Cu) veins, forming porphyry-epithermal ore systems. In the East Qinling ore belt, the genetic type of the large-scale vein-type Ag, Pb, Zn, and Au mineralization has not been determined. This study provides evidence for the occurrence of intermediate-sulfidation epithermal Ag-Pb-Zn-Au(-Cu) mineralization in the Xiayu orefield.

Summary: Understanding the crustal growth, reworking, and geodynamics of the northern continental margin of Gondwana during the Ediacaran to Silurian times is crucial for the paleogeographic reconstruction of Gondwana. This study uses various analytical methods to evaluate the magmatic history of this region and obtain relevant detrital zircon data. The results provide valuable insights into the crustal evolution and tectonic activities in the northern Gondwana region.
