Sedimentology, EarlyView.ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

The Magnetic Signature of Shear Zones in Marbles and Experimental Simulations
Geoscience Data Journal, Volume 13, Issue 4, October 2026.This dataset explores how strain, microstructure, texture and magnetic susceptibility interact in natural and experimental shear zones. It includes data from low‐ and high‐temperature marble shear zones and analogue experiments simulating different deformation regimes.

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman
Journal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract Genetic enhancement of crop plants such as kola [Cola nitida (Vent) Schott. & Endl.] can be made effective and efficient via estimates of genetic parameters. Our study evaluated genetic parameters to provide insights into heritable variability and character associations in kola to guide variety development.

The Depositional Record, Volume 12, Issue 4, September 2026.This study investigates the sedimentology and geochemistry of recent sediments from ephemeral river systems on Hurd Peninsula, Livingston Island, Antarctica. These systems are important for understanding sedimentary and geochemical processes in unique polar environments.

CHIME dating of monazite from pelitic hornfels of the Kurihashi Granodiorite, Kitakami Mountains
, 1996 1996-12The Cretaceous Kurihashi Granodiorite in the Kitakami Mountains contains no monazite grain. To date the emplacement time of the Kurihashi Granodiorite by the CHIME method, monazite in a hornfels from the immediate contact of the granodiorite ...
