STRATIGRAPHY AND DIAGENESIS OF THE THAMAMA‐B RESERVOIR ZONE AND ITS SURROUNDING DENSE ZONES IN ABU DHABI OILFIELDS AND EQUIVALENT OMAN OUTCROPS

open access: yesJournal of Petroleum Geology, Volume 47, Issue 4, Page 395-430, October 2024.
We review published studies characterizing the Thamama‐B reservoir zone in the upper Kharaib Formation (late Barremian) in Abu Dhabi oilfields and at outcrops in Oman. Available data for oxygen and carbon isotope compositions, fluid inclusion measurements, cement abundance and formation water composition are interpreted in terms of a paragenetic model ...

Carboniferous Barrovian to Permian Buchan‐type metamorphic cycles in the Mongolian Altai Zone: Implication for pressure cycles in accretionary orogens

open access: yesJournal of Metamorphic Geology, Volume 42, Issue 7, Page 979-1033, September 2024.
Abstract In the Altai Accretionary Wedge, several periods of Barrovian‐ and Buchan‐type metamorphic cycles were dated from Ordovician to Permian. However, the timing and link between these cycles are not clear, and their causes are debated. In order to contribute to the understanding of Barrovian‐ to Buchan‐type evolution of the accretionary wedges, we

How the Sima de los Huesos was won

open access: yesThe Anatomical Record, Volume 307, Issue 7, Page 2225-2245, July 2024.
Abstract Although the first discovery of a human fossil in the Sima de los Huesos took place in 1976, systematic excavations did not begin there until 1984. Since then, this site has been continuously excavated in month‐long camps. The site is dated by different radiometric techniques to between 430,000 and 300,000 years ago.

Volcanic Unrest After the 2021 Eruption of La Palma

open access: yesGeophysical Research Letters, Volume 51, Issue 11, 16 June 2024.
Abstract La Palma, Canary Islands, had its largest historical eruption in 2021. From January 2022 to May 2023 there were >2,100 seismic events, primarily at depths ≤20 km, prompting us to update the deformation and modeling study, using interferometric synthetic aperture radar observations and a last generation interpretation tool.
