Impacts of Pre‐Existing Structural Fabrics on Fault Growth and Evolution During Multi‐Phase Rifting: Case Study From the Central Browse Basin, North West Shelf of Australia

open access: yesBasin Research, Volume 37, Issue 4, July–August 2025.
This study examines the development of fault patterns in a multi‐phase rift system and demonstrates how pre‐existing faults influence the geometries and distribution of subsequent fault systems. ABSTRACT In multi‐phase rifts, pre‐existing structural fabrics that are formed during earlier rifting stages can influence fault growth during later ...

Barremian and Aptian (Cretaceous) sharks and rays from Speeton, Yorkshire, north-east England [PDF]

open access: yes, 2004
Bulk sampling of a number of horizons within the upper part of the Speeton Clay Type section has produced teeth and other remains of sharks and rays from several poorly studied horizons.

Geochemical evaluation of black limestones in the Early Cretaceous platform carbonates of Gümüşhane (NE Turkey): An insight into petroleum source rock potential and palaeoenvironment conditions

open access: yesThe Depositional Record, Volume 11, Issue 3, Page 917-953, June 2025.
Some layers of limestone produce some hydrocarbons, and these hydrocarbons are removed from the fractures and cracks of the rock. The organic matter (OM) contained in the limestone is a mixture of terrestrial and marine OM and is thermally immature and mature.

Paguroid anomurans from the upper Tithonian–lower Berriasian of Štramberk, Moravia (Czech Republic)

open access: yesGeologija, 2020
Subsequent to a preliminary report on a handful of paguroid remains from the Tithonian (uppermost Jurassic) to lower Berriasian (Lower Cretaceous) Štramberk Limestone in Moravia (eastern Czech Republic), published in 2013, several field campaigns were ...

Geological reassessment of syn‐rift extensional sequences in the Shine Usny Tolgod and Dzun Shakhai fossil localities, Eastern Gobi Basin, Mongolia

open access: yesSedimentology, Volume 72, Issue 4, Page 1275-1315, June 2025.
ABSTRACT Sedimentary infill patterns in the Eastern Gobi Basin of southern Mongolia record a complex, polyphased history. Asynchronous timing and intensities of extensional tectonism during the Early Cretaceous fragmented the Eastern Gobi Basin into a series of sub‐basins within an extensional rift (horst‐graben) setting, which likely infilled ...

Relative sea-level change, climate, and sequence boundaries: insights from the Kimmeridgian to Berriasian platform carbonates of Mount Salève (E France) [PDF]

open access: yes, 2018
The present study analyses the stratal architecture of the Late Jurassic (Kimmeridgian) to Early Cretaceous (Berriasian) sedimentary succession of Mount Salève (E France), and four Berriasian stratigraphic intervals containing four sequence-boundary ...

New Kinematic Model of the Early Opening of the Equatorial Atlantic Realm

open access: yesTectonics, Volume 44, Issue 5, May 2025.
Abstract The opening of the Equatorial Atlantic Ocean constitutes the final stage of Gondwana's breakup, leading to the separation of the African and South American continents. The early spreading has been debated due to the absence of magnetic anomalies related to the Early Cretaceous opening at low latitude, and an incomplete fracture zone record ...

Salt Diapirs and Minibasins Along a Transect Across the Basque‐Cantabrian Pyrenees: Implications for Cover‐Basement Interaction During Rifting and Inversion

open access: yesTectonics, Volume 44, Issue 5, May 2025.
Abstract The Basque‐Cantabrian Pyrenees experienced Early Cretaceous rifting and latest Cretaceous to Cenozoic inversion, with the presence of prerift Upper Triassic Keuper salt influencing how deformation was accommodated. Considerable disagreement exists on the degree of decoupling of supra‐ and subsalt deformation, the amount of thin‐skinned ...

CRETACEOUS PALYNOLOGY (SPORES, POLLEN AND DINOFLAGELLATE CYSTS) OF THE SIQEIFA 1-X BOREHOLE, NORTHERN EGYPT

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2007
Diverse and well preserved palynofloras were recognized in the Lower Cretaceous succession penetrated by well Siqeifa 1-X in northern Egypt. Dinoflagellate cysts such as Subtilisphaera senegalensis was regarded, with the spores Impardecispora ...

Paleoenvironmental evolution of the southern Neuquèn basin (Argentina) during the Tithonian-Berriasian (Vaca Muerta and Picún Leufú Formations): a multi-proxy approach

open access: yesBSGF - Earth Sciences Bulletin, 2017
The Tithonian-Berriasian interval in the southern part of the Neuquén Basin is represented by the Vaca Muerta and the Picún Leufú Formations. Facies analysis and correlation of the Vaca Muerta Formation and the lower part of the Picún Leufú Formation in ...
