Episodic Seafloor Hydrothermal Alteration as a Source of Stable Remagnetizations in Archean Volcanic Rocks

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 12, December 2024.
Abstract Interpreting the paleomagnetic records of altered rocks, especially those from Earth's earliest history, is complicated by metamorphic overprints and recrystallization of ferromagnetic minerals. However, these records may be as valuable as a primary signal if the timing and mechanism of alteration‐related remagnetizations can be ascertained ...

Zircon Xenocrysts From Easter Island (Rapa Nui) Reveal Hotspot Activity Since the Middle Jurassic

AGU Advances, Volume 5, Issue 5, October 2024.
Abstract We report the finding of mantle‐derived zircon grains retrieved from red soils, regoliths, and beach sands from Easter Island, that are much older than the island volcanism (0–2.5 Ma) and its underlying lithosphere (Pliocene, 3–4.8 Ma). A large population of 0–165 Ma old zircons have coherent oxygen (δ18O 3.8–5.9‰) and hafnium (εHf(t)+3.5–+12 ...

Diverse approaches to protecting biodiversity: The different conservation measures discussed as possible other effective area‐based conservation measures

Conservation Letters, Volume 17, Issue 4, July/August 2024.
Abstract Other effective area‐based conservation measures (OECMs) create opportunities for a wide range of area‐based conservation strategies. As countries seek to integrate OECMs into conservation planning, it is useful to consider the types of areas that might meet the formal criteria.
