    Unique composition and evolutionary histories of large low velocity provinces by James Panton, J. Huw Davies, Paula Koelemeijer, Robert Myhill, Jeroen Ritsema

    Published 2025-02-01
    “…Abstract The two “large low velocity provinces” (LLVPs) are broad, low seismic wave speed anomalies in Earth’s lower mantle beneath Africa and the Pacific Ocean. Recent research suggests they contain relatively dense subducted oceanic crust (SOC), but the relative concentration of this recycled material within them is an open question. …”

    Enhanced phosphorus weathering contributed to Late Miocene cooling by Yi Zhong, Zhiguo Li, Xuefa Shi, Terry Isson, Jimin Yu, Sev Kender, Zhou Liang, George E. A. Swann, Alex Pullen, Michael E. Weber, Jinlong Du, Juan C. Larrasoaña, Jingyu Zhang, Yafang Song, F. J. González, Stefanie Kaboth-Bahr, Hai Li, Qi Zhang, Debo Zhao, Wei Cao, Mingyu Zhao, Qingsong Liu

    Published 2025-01-01
    “…Here, we present magnetic and geochemical paleoceanographic proxies from a hydrogenetic ferromanganese crust retrieved in the northwestern Pacific Ocean. Our results indicate a striking 50% surge in deep ocean phosphorus concentrations occurred 7 – 4 million years ago, synchronous with enhanced deep ocean oxygen consumption. …”
