The Magnetic Mineralogy of Carbonaceous Chondrites: A Microscopy and Machine Learning Study of Meteorite WIS 91600

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract A central challenge in the paleomagnetic study of meteorites is to characterize their diverse remanence carriers. Here, we develop a machine‐learning assisted workflow that combines multi‐scale (mm to nm) and multi‐dimensional (2D‐3D) microscopy to build a comprehensive picture of ferromagnetic mineralogy in the C2 ungrouped carbonaceous ...

Borehole Waters From Hole U1601C (Atlantis Massif) Provide Constraints for a Deep‐Sourced Formation Water That (Could) Feed the Lost City Hydrothermal Field

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Hole U1601C, drilled during International Ocean Discovery Program (IODP) Expedition 399, reached a depth of 1,268 m below the seafloor (mbsf) in the Atlantis Massif (30°N, 42°W). This borehole represents only one of six boreholes that extends more than 700 m into oceanic rock, penetrating predominantly ultramafic lithologies, mostly composed ...
