The regional evolution of a dryland fluvio‐aeolian and lacustrine succession in response to allocyclic forcing: insights from the Early Permian Cutler Group, Utah, USA

open access: yesSedimentology, Volume 73, Issue 2, Page 297-354, February 2026.
ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.

Soft‐bedded ice sheet in hummocky terrain of north‐central Poland: Origin of rim ridges and subglacial processes

open access: yesSedimentology, Volume 73, Issue 2, Page 540-559, February 2026.
ABSTRACT Hummocky terrains are characterised by various geomorphological features that typically record processes associated with the downwasting of ice sheets. Common landforms in these areas include ramparts, linear ridges, kettle holes and ice‐walled lake plains.

Control of salt structures on hydrocarbons in the passive continental margin of West Africa

open access: yesPetroleum Exploration and Development, 2011
Salt basins along the passive continental margin of West Africa are becoming one of the most attractive areas for hydrocarbon exploration. The oil and gas discovered recently are related to salt structures.

A Return to Chalosse Cherts: An Integrated Approach Based on Field Survey, Petrography and Geochemical Analysis to Understand a Palaeolithic Tracer

open access: yesGeoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT The Pyrenees have been considered a natural barrier for prehistoric populations. However, in recent years, Palaeolithic research has established connections between the two sides through the analysis of cherts. Among others, the presence of Chalosse cherts in sites on the southern slopes of the Pyrenees has proven the mobility of objects and ...

Imaging of Magma Intrusion Below La Palma During a Strong Effusive Eruption in 2021 Inferred From Repeated Seismic Tomography

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The 2021 eruption of Cumbre Vieja on La Palma, Canary Islands, provided a unique opportunity to investigate the dynamics of magma migration and storage during a large effusive eruption. In this study, we employ repeated seismic tomography to image temporal changes in the subsurface structure beneath La Palma, using body‐wave travel times from ...

Hierarchical x-fem applied to n-phase flow [PDF]

open access: yes, 2009
In this work we proposed an extencion of the level set technique to track any number of free surfaces. This extension is based in a hierarchical ordering of several level set functions.

3D modelling from outcrop data in a salt tectonic context: Example from the Inceyol mini-basin, Sivas Basin, Turkey [PDF]

open access: yes, 2016
International audienceWe propose a 3D modelling strategy of the encased mini-basin of Inceyol in Sivas (Turkey). The challenge lies in the combination of sparse outcrop data and the complex interpretive geometry of geological structures that comes from ...

Dynamic Controls on Salt Structures and Translation Velocity at Continental Rifted Margins

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Salt tectonics at rifted margins involves intricate interactions between weak, viscous evaporite layers and brittle sedimentary rocks. Geophysical data and geological interpretation offer valuable insights into evaporite structure formation and the average translation rate of evaporite and sediment layers on time scales of several million ...
