    Isotopic Age of the Xiong’er Group Volcanic Rocks and Its Geological Significance in Western Henan, China by Wenchao Dong, Xucheng Pang, Weixun Qu, Guangshun Hou

    Published 2022-01-01
    “…Combined with previous studies on isotope and rock geochemistry of volcanic rocks in the Xiong’er Group, it was believed that the formation ages of the volcanic rocks of the Xiong’er Group are between 1874 and 1618 Ma, among the ages of the Xushan Formation, Jidanping Formation, and Majiahe Formation, which were concentrated between 1874 and 1800 Ma, 1836 and 1711 Ma, and 1780 and 1618 Ma, respectively. …”

    Hazard Scenarios Related to Submarine Volcanic-Hydrothermal Activity and Advanced Monitoring Strategies: A Study Case from the Panarea Volcanic Group (Aeolian Islands, Italy) by Davide Romano, Alessandro Gattuso, Manfredi Longo, Cinzia Caruso, Gianluca Lazzaro, Andrea Corbo, Francesco Italiano

    Published 2019-01-01
    “…The “unrest” of the volcanic activity was triggered by a sudden input of deep magmatic fluids, which caused boiling water at the sea surface with a massive CO2 release besides changes in the fluids’ geochemistry. That event dramatically pushed scientists to develop new methods to monitor the seafloor venting activity. …”

    A probabilistic model-based approach to assess and minimize scaling in geothermal plants by Pejman Shoeibi Omrani, Jonah Poort, Eduardo G. D. Barros, Hidde de Zwart, Cintia Gonçalves Machado, Laura Wasch, Aris Twerda, Huub H. M. Rijnaarts, Shahab Shariat Torbaghan

    Published 2025-01-01
    “…The proposed modelling framework to demonstrate the optimization under uncertainty workflow consists of a multiphase flow solver coupled with a geochemistry model and an uncertainty quantification workflow to locally estimate the probability of precipitation potential, including its impact on the hydraulic efficiency of the geothermal plant by increasing the roughness and/or decreasing the diameter of the casings and pipelines. …”

    Solid–liquid phase change in planetary cores by Huguet, Ludovic, Kriaa, Quentin, Alboussière, Thierry,  Le Bars, Michael

    Published 2024-12-01
    “…Besides, due to the inaccessible nature of the planetary deep interior, our understanding relies on indirect data from seismology, mineral physics, geochemistry, and magnetism. Consequently, phase-change-driven flows in planetary cores constitute a compelling yet challenging area of research. …”

    Triassic evolution of the Adriatic-Dinaridic platform’s continental margins—insights from rare dolerite subvolcanic intrusions in External Dinarides, Croatia by Slovenec, Damir, Belak, Mirko, Badurina, Luka, Horvat, Marija, Šegvić, Branimir

    Published 2023-01-01
    “…Petrography of the studied rocks revealed the crystallization order: clinopyroxene ${\rightarrow }$ plagioclase ${\rightarrow }$ alkali-feldspar ${\pm }$ amphibole ${\pm }$ Fe–Ti oxides. The geochemistry of calc-alkaline dolerite suggested magma generation from a spinel–garnet bearing peridotite mantle source (60sp:40grt). …”

    Persistent functional and taxonomic groups dominate an 8,000-year sedimentary sequence from Lake Cadagno, Switzerland by Paula Rodriguez, Jasmine S. Berg, Longhui Deng, Longhui Deng, Hendrik Vogel, Michal Okoniewski, Mark A. Lever, Mark A. Lever, Cara Magnabosco

    Published 2025-02-01
    “…Despite these dramatic changes in taxonomic community composition and sediment geochemistry throughout the sediment core, higher-order functional categories and metabolic marker gene abundances remain relatively consistent and indicate a microbial community capable of carbon fixation, fermentation, dissimilatory sulfate reduction and dissimilatory nitrate reduction to ammonium. …”
