Effect of Fluorine on the Stability of Dense Hydrous Mg Silicates With Implications for the Deep Water Cycle

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Water is believed to be transported, at least locally, into the Earth's deep mantle via hydrous minerals. Fluorine not only tends to interact with water but also influences the stability of hydrous minerals. Thus, knowledge of its stability could be important in understanding the deep‐water cycle.

Eocene to Miocene U‐Pb Geochronology Evolution of the Rio Grande Rise, Southwestern Atlantic: A Paleoceanographic Approach

Paleoceanography and Paleoclimatology, Volume 41, Issue 8, August 2026.
Abstract The Rio Grande Rise (RGR) is a major submarine feature in the South Atlantic that plays an important role in regional oceanographic dynamics. This study presents new U‐Pb geochronology of sedimentary rocks from the RGR, offering direct age constraints on carbonate and apatite embedded within Fe‐Mn crusts and associated foraminifera fossils ...

Inversion by Intrusion: Magma‐Driven Shortening in the Turkana Rift (East Africa)

Tectonics, Volume 45, Issue 8, August 2026.
Abstract Late Pliocene to Pleistocene inversion in the Turkana Rift, observed on seismic reflection data and in outcrop, presents a tectonic paradox by indicating local shortening in an overall extensional setting. Previous studies attributed this inversion either to the reactivation of obliquely oriented structural weaknesses or to reorientation of ...

Architecture of the Patrimonio Fault System and the Miocene Post‐Orogenic Extension in Alpine Corsica (France)

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The exhumation of Alpine Corsica is the result of Oligocene‐Miocene lithospheric back‐arc extension in the wake of the eastward migration of Apenninic subduction. Although the geometry, kinematics and timing of ductile detachments are well constrained, the brittle extension leading to final exhumation of Alpine Corsica is less documented.

Drivers and Patterns of Sediment Organic Carbon in European Regional Seas

Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Mapping organic carbon (OC) stores in marine sediments is a management priority to potentially minimize the anthropogenic release of organic carbon from the seabed. Sediment OC content shows high regional variability, shaped by a complex interplay of physical, chemical, biological and anthropogenic factors.

Hydrothermal Manganese‐Oxide Mineralization of a Carbonate Ooze, Samoan Hotspot Region, South Pacific Ocean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Low‐temperature hydrothermal manganese oxides occur throughout the global oceans. However, the hydrothermal replacement of a carbonate ooze by manganese oxides is described here for the first time. The 24 samples dredged from three locations around the Territory of American Samoa in the South Pacific Ocean include six samples with remnant ...
