Growth history of fault-related folds and interaction with seabed channels in the toe-thrust region of the deep-water Niger delta [PDF]

open access: yes, 2015
The deep-water fold and thrust belt of the southern Niger Delta has prominent thrusts and folds oriented perpendicular to the regional slope that formed as a result of the thin-skinned gravitational collapse of the delta above overpressured shale.

Facies analysis provides new insights into event bed deposition in a hadal trench environment

open access: yesSedimentology, Volume 73, Issue 2, Page 441-477, February 2026.
ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...

Provenance history of a Late Triassic-Jurassic Gondwana margin forearc basin, Murihiku Terrane, North Island, New Zealand: petrographic and geochemical constraints [PDF]

open access: yes, 2004
The Murihiku Terrane in the North Island was a forearc basin adjacent to a volcanic arc along the eastern margin of Gondwana during the Mesozoic. The rocks that infill the basin are mainly volcaniclastic sandstones and mudstones, often turbiditic, with ...

Deformation of the Upper Oceanic Crust in the Outer Rise of the Sumatra Subduction Zone: Insights From P‐ and Doubly Converted S‐Wave Arrivals on Downward Continued Streamer Data

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The structure and properties of mature upper oceanic plates may evolve through mechanisms such as magmatism, hydrothermal circulation, and faulting. However, high‐resolution constraints, especially those involving both P‐ and S‐waves, remain scarce, limiting our ability to detect these processes and assess their impacts on crustal properties ...

Origin and reservoir properties of deep-water gravity flow sediments in the Upper Triassic Ch6–Ch7 members of the Yanchang Formation in the Jinghe Oilfield, the Southern Ordos Basin, China

open access: yesEnergy Exploration & Exploitation, 2019
In recent years, the Ch6–Ch7 deep-water gravity flow deposits of the Yanchang Formation in the Southern Ordos Basin have been characterised as sandy debris flow sediments, a modification from previous sedimentary facies characterisations of braided river

Biostratigraphic and magnetostratigraphic synthesis of the Celebes and Sulu Seas, Leg 124 [PDF]

open access: yes, 1991
During ODP Leg 124, late middle Eocene to Quaternary sediment sequences were recovered from 13 holes drilled at five sites in the Celebes and Sulu basins. Paleomagnetic measurements and biostratigraphic studies using calcareous nannofossils, planktonic

Guide to the geology of Bradgate Park and Swithland Wood, Charnwood Forest [PDF]

open access: yes, 2010
Charnwood Forest is one of the few parts of England where there are exposures of ‘basement’ rocks dating back to Precambrian time. Its locally rugged topography is caused by these highly resistant rocks protruding as craggy knolls through a surrounding ...

The stratigraphy, correlation, provenance and palaeogeography of the Skiddaw Group (Ordovician) in the English Lake District [PDF]

open access: yes, 1995
A new lithostratigraphy is presented for the Skiddaw Group (lower Ordovician) of the English Lake District. Two stratigraphical belts are described. Five formations are defined in the Northern Fells Belt, ranging in age from Tremadoc to early Llanvirn.
