Thermal histories of El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155): Implications for the diversity of IAB‐ungrouped iron meteorites and their parent bodies

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 8, Page 1763-1787, August 2026.
Abstract This study provides the first petrographic, crystallographic, and chemical comparison between El Médano 300 (EM 300) and Northwest Africa 8155 (NWA 8155), two particular IAB‐ungrouped iron meteorites. Both contain exceptionally large graphite nodules and “flowers”, providing unique insights into carbon behavior in metallic melts and cooling ...

Tracing methane sources in shallow waters of the North Sea: Biogenic signatures and hydrocarbon transport near abandoned wells

open access: yesLimnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Numerous abandoned wells in the North Sea may provide gas, particularly methane (CH4), migration pathways by penetrating shallow, biogenic gas accumulations. However, related sampling campaigns have been largely contradictory and lack a substantial database. Research cruise MSM98 targeted the abandoned wells B18‐1, DOK 1‐X, B11‐2, THOR and D‐1

Structural and geochronological constraints on the Permo-Triassic tectonic evolution of the southern Jinsha Orogenic Belt, eastern Tibetan Plateau

open access: yesJournal of Asian Earth Sciences: X
The southern Jinsha Orogenic Belt records the subduction-accretion-collision processes during the closure of the Paleo-Jinsha Ocean. Detailed structural analysis conducted along this belt and U-Pb zircon dating of tectonic-related plutons put robust ...

Post‐Miocene Transtensional Opening of the Northern Red Sea

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The mechanism of opening, as well as the crustal characteristics of the northern Red Sea are subject of ongoing controversial scientific debate. With the objective of elucidating the nature of rifting in this area, a grid of 2D multi‐channel reflection seismic data was acquired off the Al Wajh carbonate platform (AWCP), and supplemented by ...

Probabilistic Assessment of Variable Slip Rates of Offshore Buried Thrusts in the Central Adriatic Sea (Italy) Since the Pliocene Time

open access: yesTectonics, Volume 45, Issue 7, July 2026.
Abstract Understanding the recent tectonic activity of buried faults represents a challenge for scientists. In the offshore portion of the Northern and Central Apennines foredeep basin in the Central Adriatic Sea, Italy, high sedimentation rates, exceeding tectonic uplift since the Pliocene, and the offshore location are hampering the detection of ...
