Summary: The burial of organic carbon and mountain building during the Palaeoproterozoic era around 2 billion years ago were closely linked, with the high carbon burial playing a critical role in reducing frictional strength and lubricating compressive deformation. This relationship highlights the integral connection between the biosphere and lithosphere, impacting the long-term deformation of the Earth's crust and subsequent mountain building activities.

Summary: Research on lunar samples has revealed a phosphate mineral that records an impact event around 4.2 billion years ago and a disturbance around 0.5 billion years ago. The older event is attributed to the formation of the Serenitatis Basin, while the younger event may be related to the Dawes crater.

Summary: The study reveals that most Archean and Proterozoic carbonates do not show isotopic fractionation from the crustal and riverine compositions, which contradicts the view that the U isotopic composition of seawater simply reflects the areal extent of anoxic sediments in the past.

Summary: The study suggests that the high vanadium content in the Oklo-Okelobondo region may have originated from vanadium-rich black shales in the Upper Francevillian Group, rather than from igneous rocks or granites. These V-rich hydrocarbons likely prevented natural fission reactions from occurring in these U deposits.

Summary: Vaporization is a significant consequence of giant impacts in planet formation. The last giant impact during the early history of our planet resulted in the formation of a highly vaporized disk that condensed onto the Earth and Moon. This study investigated the thermodynamic state of the disk and its condensation process, finding that the mantle and post-impact Earth reached critical temperatures and pressures. The atomic structure of the silicate fluid within the disk varied with radius, leading to the presence of short-lived chemical species in the outer parts and long-lasting dense polymers in the deeper parts. The condensation of silicate vapor during cooling resulted in the dominance of species along the mantle vapor curve in the post-impact atmosphere.

Summary: In the leading theory of lunar formation, a collision between two planet-size objects resulted in a young Earth surrounded by a circumplanetary debris disk from which the Moon later formed. However, none of the proposed scenarios have successfully explained all the known constraints without controversial post-impact processes. To bridge this gap, researchers conducted a systematic study of simulations of potential Moon-forming impacts. The first paper focuses on pairwise impacts between nonrotating bodies, showing that a minimum initial angular momentum budget is required to generate a sufficiently massive protolunar disk. Low-velocity impacts with high impactor-to-target mass ratios are preferred to explain the Earth-Moon isotopic similarities.

Summary: This study investigates the impact of precipitation, evaporation, and salinity (P-E-S) coupling on the upper ocean and finds that heavy precipitation and strong winds associated with MJO events result in a locally fresher, warmer western Pacific warm pool with shallower mixed layer and thicker barrier layer. The fresh, warm water mass extends into the central-eastern Pacific, accompanied by a well-defined salinity/density front propagating eastward. The P-E-S coupling plays an important role in the eastward extension of the warm pool prior to the onset of El Nino in July 2018.

Summary: By studying the East Siberian Continental Margin, we have discovered preserved stable oxygen isotope and mineralogy records in the sedimentary core, which provide insights into the evolutionary history of the Siberian Ice Sheet. The records show multiple strong oxygen isotope excursions, indicating the activity of the ice sheet during past glaciations. This study advances our understanding of the development of the western Arctic Ocean basin and the impact of similar ice sheets on global climate change behavior.

Summary: The 2020 pandemic year witnessed an unprecedented retardation of spring water temperature rising in the northeastern basin of the Yellow Sea. This phenomenon was primarily caused by the significant increase in latent heat releases and exceptional heat fluxes generated by strong northwesterly winds. The warm winter water and oceanic heat redistribution also played a role in supporting the cold anomaly at the surface, resulting in the delayed and suppressed spring bloom.

Summary: This study examines the geochemical characteristics of Hadean detrital zircons from South Africa, finding that the majority of these zircons show a mantle affinity similar to zircon from modern plume-type mantle environments, rather than zircon from modern continental or oceanic arcs.

Summary: Hadean zircons from 4.0-4.2 Ga provide insight into early crustal development and surface conditions on Earth. These zircons were found in a Green Sandstone Bed layer in South Africa with a depositional age estimated at around 3.306 Ga. The findings suggest transport of windblown sediments and subaerial environments during the early stages of Earth's formation.

Summary: Sandstones from the Archean Moodies Group are some of the oldest sedimentary sequences rich in quartz. The study analyzed detrital zircon data to determine the age and provenance of the unit, showing evidence of both internal and external sources of quartz and feldspar, as well as multiple periods of felsic magmatism.

Summary: The nature and processes of Earth's early crust are still unknown in Precambrian geology. Recent research using trace element proxies for zircon formation has shed light on crustal processes. A study of materials from the Hadean period reveals a major shift in crustal processes, supporting the idea of global crustal instability and recycling.
