The Origin of Carbonate Magmas Predating and Accompanying Main‐Phase LIPs Eruptions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Some large igneous provinces (LIPs) are associated with precursory carbonatite eruptions. Models for precursory carbonatites invoking partial melting of a carbonate metasomatized lithosphere appear implausible, given the long time needed for heat conduction from the plume head.

Cosmic Dust Flux During the Quaternary: The Record of Large Scoriaceous and Unmelted Micrometeorites From the Transantarctic Mountains Collection

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract We estimate the cosmic dust flux to Earth through the study of rare micrometeorites that preserve part of their precursor features during atmospheric entry heating, namely unmelted and scoriaceous subtypes. Combining high‐precision mass balance measurements, X‐ray computed microtomography and scanning electron microscopy, we studied mass, size

Structural Evolution of the Gaggiano High: A Preserved Rift‐Related Structural High in the Western Po Plain (Italy)

Tectonics, Volume 45, Issue 7, July 2026.
Abstract The Gaggiano High, buried beneath the sediments of the Western Po Plain (northern Italy), represents one of the few examples of Mesozoic structural highs largely preserved within a foreland–foredeep system. Unlike the adjacent Lacchiarella Basin, which underwent strong positive inversion during the Neogene, the Gaggiano High experienced only ...

Non‐Uniqueness, Symmetries and Invariance of Thermal History Modelling in Sedimentary Basins

Basin Research, Volume 38, Issue 4, July–August 2026.
This paper approaches non‐unique inverse problems by generating a representative ensemble of all possible solutions using the concept of symmetry. In the context of basin modelling, a symmetry is any manipulation of a forward model's parameters (e.g., thermal history) that leaves the model output (e.g., downhole vitrinite reflectance) unchanged ...
