The Spatial and Temporal Evolution of Mixed Carbonate‐Clastic Mud‐Dominated Basin Fill Successions: The Middle to Late Devonian Shelf Margin, Western Canada

open access: yesBasin Research, Volume 37, Issue 6, November/December 2025.
The spatial interplay between updip clastic and carbonate depositional systems and downdip detrital and biogenic mud dominated depositional systems are mapped temporally using the sequence stratigraphic method to predict the occurrence of aquifers, petroleum reservoirs and organic‐rich deposits. ABSTRACT Middle to Upper Devonian strata preserved in the

Carbonate microfacies and transgressive‐regressive sequences of Oxfordian shallow‐water limestones (Korallenoolith, Lower Saxony Basin)

open access: yesThe Depositional Record, Volume 11, Issue 4, Page 1084-1106, September 2025.
The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.

Undulating stratigraphy of a carbonate inner ramp lagoon and associated architectural facies heterogeneity: An example from the Late Jurassic Hanifa Formation, Central Saudi Arabia

open access: yesSedimentology, Volume 72, Issue 3, Page 734-762, April 2025.
Abstract This study offers new insights into the internal architecture of shallow marine carbonate sediments deposited in an epeiric sea formed on a broadly flooded passive margin continental shelf. The Ullayah Member of the Late Jurassic Hanifa Formation is exposed along the Tuwaiq Mountain Escarpment in Central Saudi Arabia and serves as an example ...

Exploring electron backscatter diffraction analysis as a tool for understanding stromatolite: Quantitative description of Cretaceous lacustrine stromatolite reveals formative processes and high‐resolution climatic cycles

open access: yesSedimentology, Volume 71, Issue 7, Page 2448-2469, December 2024.
Abstract Lacustrine stromatolites serve as important archives for recording environmental changes, and the detailed examination of their microfabrics is essential for understanding their formative processes and the environmental changes embedded within them.

How to engineer a habitable planet: the rise of marine ecosystem engineers through the Phanerozoic

open access: yesPalaeontology, Volume 67, Issue 5, September/October 2024.
Abstract Ecosystem engineers are organisms that modify their physical habitats in a way that alters resource availability and the structure of the communities they live in. The evolution of ecosystem engineers over the course of Earth history has thus been suggested to have been a driver of macroevolutionary and macroecological changes that are ...

Stromatoporoid beds and flat-pebble conglomerates interpreted as tsunami deposits in the Upper Silurian of Podolia, Ukraine [PDF]

open access: yes, 2014
Tsunami deposits are currently a subject of intensive studies. Tsunamis must have occurred in the geological past in the same frequency as nowadays, yet their identified depositional record is surprisingly scarce. Here we describe a hitherto unrecognized

Authigenic Carbonate Burial Within the Late Devonian Western Canada Sedimentary Basin and Its Impact on the Global Carbon Cycle

open access: yesGeochemistry, Geophysics, Geosystems, Volume 25, Issue 3, March 2024.
Abstract Stable carbon isotope ratios (δ13C values) of marine carbonates are widely used to infer the relative burial rates of organic carbon, a source of oxygen to the ocean‐atmosphere system. This inference, however, is based on the assumption that ocean‐atmospheric carbon is buried either as organic carbon or as marine carbonate minerals. The burial
