Questioning carbonate facies model definition with reference to the Lower Cretaceous Urgonian platform (SE France Basin)

BSGF - Earth Sciences Bulletin, 2023
Designing carbonate facies models requires the integration, correlation and conceptual interpretation of multiple geological data sets. Potential significant errors are sourced from uncertain stratigraphic correlations, speculative palaeoecological ...

Fluctuations of sea-water chemistry during Gargasian (Middle Aptian) time. Data from trace-element content (Mg, Sr, Mn, Fe) in hemipelagic carbonates from La Marcouline Quarry (Cassis, SE France)

Carnets de Géologie, 2007
In the Lower Aptian historical stratotype area (Cassis-La Bédoule, SE France), a geochemical study of the Gargasian (Middle Aptian) marl-limestone alternations of the La Marcouline quarry complements data already obtained from Bedoulian (Early Aptian ...

A new small-bodied azhdarchoid pterosaur from the Lower Cretaceous of England and its implications for pterosaur anatomy, diversity and phylogeny [PDF]

, 2013
BACKGROUND: Pterosaurs have been known from the Cretaceous sediments of the Isle of Wight (southern England, United Kingdom) since 1870. We describe the three-dimensional pelvic girdle and associated vertebrae of a small near-adult pterodactyloid from ...

Biogenic structures in test of large benthic foraminifers (Orbitolina): Example from Aptian-Albian sediments of SW Neo-Tethys Ocean, Zagros, SW Iran [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2018
Introduction Study of carbonate sediments of the Dariyan Formation (Aptian-Albian) in northwest of Shiraz releases different types of biogenic structures in forms of encrustation and drilling in hard substrates. Generally biogenic structures are referred

Aptian–Albian deposits of the Ait Ourir basin (High Atlas, Morocco): New additional data on their paleoenvironment, sedimentology, and palaeogeography

Open Geosciences, 2020
This sedimentological and palaeontological analysis of the Aptian–Albian sedimentary succession of the Ait Ourir basin in the High Atlas Mountains of Marrakesh in Morocco provides new data from a previously poorly understood basin.

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

, 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.

Early-Late Cretaceous (Aptian-Cenomanian) Palynomorphs [PDF]

Journal of Micropalaeontology, 1985
Abstract. Samples from 12 wells situated mainly in the northern part of the Cyrenaica Shelf of northeast Libya have yielded palynomorph assemblages of Aptian, Albian or Cenomanian aspect. The Aptian assemblages are dominated by land-plant remains and contain relatively few dinoflagellate cysts. By contrast, the latter are generally common in those from

Shark and ray teeth from the Hauterivian (Lower Cretaceous) of north-east England [PDF]

, 1999
Sampling of hiatal horizons within the Hauterivian part of the Speeton Clay Formation of north-east England has produced teeth of several species of sharks and rays, four of which are previously unnamed.
