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

Geoarchaeology, 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 ...

Some features of deformation structures in an esker on the southern margin of the Fennoscandian shield [PDF]

Bulletin of the Geological Society of Finland, 2018
As a result of melting of the last ice sheet in the southeastern edge of the Fennoscandian shield, ridge structures called eskers were formed. One of these eskers is the subject of our study.

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

Journal 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 ...

Submarine channels ‘swept’ downstream after bend cutoff in salt basins

The Depositional Record, 2020
Channel‐bend expansion and downstream translation, as well as vertical movements by aggradation and incision, set the stratigraphic architecture of channelized depositional systems.

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

Journal 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 ...

Study on the planar structure characteristics of mud diapirs in Rio del Rey basin , West Coast of Africa(非洲西海岸里奥-德雷盆地泥底辟平面地质结构特征研究)

Zhejiang Daxue xuebao. Lixue ban
The Rio del Rey basin, located in the eastern margin of the Niger Delta Basin in West Africa, develops large-scale mud diapirs. There are some disputes about the activity time and mechanism of the diapirs. Based on the detailed interpretation and mapping

Seismological Characterization of Northern Hikurangi Margin Slow Slip Regions Associated With Normal Faults, Seamounts, and Seeps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract At the northern Hikurangi margin, Aotearoa New Zealand, slow slip events (SSEs) recur every 6–24 months to ∼ ${\sim} $30 km depth. Although shallow SSEs (0–10 km) are well‐studied offshore, the deeper portion (10–30 km) remains poorly understood, limiting insight into SSE initiation.

An investigation into the impact of diapir structures on formation pressure systems: a case study of the Yinggehai Basin, China

Geothermal Energy
Under the influence of diapir structure, the formation pressure system is complicated. The characteristics of high temperature and high pressure are obvious, the prediction is difficult, and complex accidents such as well kick and leakage are frequent ...

“Salt Tectonics” on Titan: Radial Labyrinths as Topographic Expressions of Solid‐State Flow

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Surface observations of Saturn's moon Titan revealed features characterized as dissected, elevated plateaus with high valley density known as labyrinth terrains. Of this terrain class, a subtype referred to as radial labyrinth is described as dome‐shaped uplifts with radial channel patterns.
