In this work, we present a numerical model dedicated to the simulation of friction and wear in an idealized fault asperity, taking inspiration from an experimental device used in a companion paper. The model can simulate the progressive damaging of the fault rock close to the contact, the release of fault gouge in the interface, and its circulation in the asperity and ejection from it. This allows to explore the complex interplay between a geometrical asperity and a gouge layer, in the presence of wear. Numerical results show that the asperity spontaneously evolves toward a tribological steady state in terms of friction, wear rate, roughness, and gouge thickness, in qualitative (and sometimes quantitative) agreement with experiments. We show that the existence of a geometrical asperity does not preclude the presence of a persistent gouge layer, which properties control the tribological response of the interface, and we emphasize the importance of understanding the mechanical, geometrical and rheological factors controlling its thickness.</p>","PeriodicalId":15864,"journal":{"name":"Journal of Geophysical Research: Solid Earth","volume":"130 7","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2025JB031345","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144695835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, here we present updated projections of TCs for the southwest Pacific from a high-resolution downscaled ensemble of CMIP6 models. The downscaling implements a variable-resolution atmospheric model enhancing resolution over the southwest Pacific and New Zealand (∼12–30 km). We assess future changes in TC frequency, changes in large-scale environmental conditions, and associated extreme precipitation and winds across tropical and ex-tropical storm phases. Changes in TC track pathways are also investigated through cluster analysis. Across the downscaled simulations, robust changes in TC frequency were not found, including for a high-emissions scenario at end-of-century. Projections of the background environmental conditions are shown to be a significant source of uncertainty, owing to diverging projections of relative SST and tropical convection across the region in the host GCMs. However, very strong TCs (category 4 and above) show greater consensus for an increase in frequency, with 16 of 18 simulations across models and scenarios projecting an increase. Cluster analysis of TC tracks indicates a slight decrease in tracks that often impact northern parts of Australia. Extreme precipitation associated with TCs under a high-emissions scenario is projected to increase by ∼30%–35% averaged across models, both for storms in the tropics and ex-TCs impacting New Zealand. This increase exceeds Clausius-Clapeyron scaling in five of six simulations. These projected increases in associated extreme precipitation pose significant societal risks despite the remaining uncertainty in TC frequency changes.</p>","PeriodicalId":15986,"journal":{"name":"Journal of Geophysical Research: Atmospheres","volume":"130 14","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2025JD043833","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144705429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the petrology, bulk geochemistry, and mineral chemistry of drill holes from the deep Platreef at Sandsloot, downdip from the established Sandsloot open pit, are examined, with the aim of establishing the magmatic stratigraphy. This newly described sequence is composed of up to six discrete pyroxenitic packages, with significant PGE and base metal mineralization observed in two consistent units: the PGE reef and the Base Metal zone. Varying CaO/Al2O3 ratios and mineral and alteration assemblages are associated with different units, alluding to varying degrees of carbonate contamination and hydrothermal alteration. Variations in parental magma compositions for the identified units are equivocal. The PGE reef and Ni-rich Base Metal zone are strongly associated with contamination from the underlying Malmani subgroup dolomites (indicated by CaO/Al2O3 ratios ≥ 2), and although this is not exclusive to the mineralized horizons, the highest PGE grades all show this signature. The stratigraphy of the deep Platreef at Sandsloot is difficult to correlate with other sections of deep Platreef/Critical zone in the northern Bushveld, which is likely a function of complex and localized contamination, and an emplacement history of discrete sills/fingers of barren and PGE-rich magmas. Notwithstanding the localized contamination, it is apparent that only some of the magmatic pulses that formed the Critical zone succession in the northern limb were PGE rich.","PeriodicalId":11469,"journal":{"name":"Economic Geology","volume":"22 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144712296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a two-dimensional (2-D) particle-in-cell (PIC) simulation model, we have thoroughly studied the evolution of ECH waves under various initial plasma conditions by relaxing anisotropic hot electrons with a loss-cone distribution. Overall, ECH waves are significantly suppressed once whistler waves appear, and their damping rate is strongly dependent on the amplitude of whistler waves, which is positively correlated with the hot electron proportion and the temperature anisotropy.
