Geochemical Disequilibrium at the Brittle‐Ductile Transition
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract We investigate the microtextural, microchemical, and isotopic effects of late‐stage ductile deformation in quartzite mylonites and kyanite–muscovite–quartz veins from the Raft River shear zone (Utah). Quartz microstructures record pervasive disequilibrium, expressed by unannealed features including undulatory extinction, deformation lamellae ...

, 1993 Structural setting, stratigraphic relationships, paleontolgical character and sedimentology of Paleogene deposits cropping out in Cabrera Islands are described. They correspond to sandy to silty limestones building up a transgressive-regressive cicle that correlates with s'Envestida Calcarenites Fm. defined in Mallorca Is.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract Igneous Plumbing Systems in sedimentary basins comprise a complex of interconnected intrusive bodies that lead to volcano formation, though their 3D distribution and dynamics are not fully understood. We characterized the post‐breakup igneous plumbing systems at the Santos and Campos Basins using wells and 3D high‐resolution seismic and ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract Tectonic CO2 Earth degassing is globally relevant and has probably controlled climate on a geological scale (Brune et al., 2019, https://doi.org/10.1038/s41561‐017‐0003‐6). Endogenous CO2 outgassing from rifting areas remains poorly constrained, with most available data from the East African Rift.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions. The southwestern Pacific International Ocean Discovery Program (IODP) Site U1553, with its almost complete succession of the ...
