2024por Dallai, Luigi, Bianchini, Gianluca, Avanzinelli, Riccardo, Natali, Claudio, Conticelli, Sandro“…Magmas in volcanic arcs have geochemical and isotopic signatures that can be related to mantle metasomatism due to fluids and melts released by the down-going oceanic crust and overlying sediments, which modify the chemistry and mineralogy of the mantle wedge. …”

2025“…The small upper Pleistocene diatreme of Polino (central Italy) is known in literature as one of the few monticellite alvikites (volcanic Ca-carbonatite) worldwide. This outcrop belongs to the Umbria-Latium Ultra-alkaline District (ULUD), an area characterized by scattered and small-volume strongly SiO(2)-undersaturated ultrabasic igneous rocks located in the axial sector of the Apennine Mts. in central Italy. …”

2027por Greene, S. E., Ridgwell, A., Kirtland Turner, S., Schmidt, D. N., Pälike, H., Thomas, E., Greene, L. K., Hoogakker, B. A. A.“…From our data synthesis and modeling, we suggest that observations of warming, declining δ(13)C and a relatively stable CCD can be broadly reproduced by mid‐Paleogene increases in volcanic CO(2) outgassing and weathering. However, remaining data‐model discrepancies hint at missing processes in our model, most likely involving the preservation and burial of organic carbon. …”

This is the first evidence of non-native species reaching the Antarctic continent alive on kelp rafts. …”

P., Kuan, Pou-Long, Tseng, Yung-Che, Hwang, Pung-Pung, Quijada-Rodriguez, Alex R., Weihrauch, Dirk“…Shallow hydrothermal vent environments are typically very warm and acidic due to the mixing of ambient seawater with volcanic gasses (> 92% CO(2)) released through the seafloor making them potential ‘natural laboratories’ to study long-term adaptations to extreme hypercapnic conditions. …”

Volcanic degassing of carbon dioxide (CO(2)) and silicate chemical weathering are known to regulate the evolution of climate on a geologic timescale (> 10(6) yr), but the relationship between the solid earth and the shorter (< 10(5) yr) fluctuations of Quaternary glacial–interglacial cycles is still under debate. …”

Analysis of geochemistry and sedimentation suggests a hydrothermal source of the metals, where the mineralization of V is related to clay and organic matter. …”
