A GUIDE-LEVEL OF THE UPPERMOST HAUTERIVIAN (LOWER CRETACEOUS) IN THE PELAGIC SUCCESSION OF UMBRIA-MARCHE APENNINES (CENTRAL ITALY): THE FARAONI LEVEL

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
The definition of a regional guide-level, named Faraoni Level, in the Maiolica limestone of the Umbria-Marche Apennines is proposed in this paper. The age of the Faraoni Level is latest Hauterivian.

Uppermost Jurassic to Lower Cretaceous benthic foraminiferal biostratigraphy at ODP Site 765 on the Argo Abyssal Plain. [PDF]

open access: yes, 1992
Benthic foraminifers were studied in 99 samples collected from the lower 200 m of Hole 765C. The studied section ranges from the Tithonian to Aptian, and benthic foraminifers can be subdivided into five assemblages on the basis of faunal diversity and ...

Geochemical and Seismic Constraints on the Role of Mud Diapirs in Petroleum Migration and Accumulation in the Recôncavo Basin, NE Brazil

open access: yesJournal of Petroleum Geology, Volume 49, Issue 2, Page 433-447, April 2026.
ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...

The sinemydid turtle Ordosemys from the Lower Cretaceous Mengyin Formation of Shandong, China and its implication for the age of the Luohandong Formation of the Ordos Basin [PDF]

open access: yesPeerJ, 2019
Chronostratigraphic correlation of terrestrial Early Cretaceous biotas in China is highly problematic due to the lack of marine deposits, few absolute dates, and limited number of index fossils.

A revision of the Lower Cretaceous foraminiferal genus Falsogaudryinella from northwest Europe and Romania, and its relationship to Uvigerinammina [PDF]

open access: yes, 1995
We emend the definition of the foraminiferal genus Falsogaudryinella Bartenstein, 1977 based on observations of the type species, F. tealbyensis from the Barremian Lower Tealby Clay of Lincolnshire, U.K.

Tectonostratigraphic Evolution of the Guyana Basin: Implications for Sediment Routing and Slope Stability

open access: yesBasin Research, Volume 38, Issue 2, March/April 2026.
Seismic profile across the Guyana Basin showing the main tectonostratigraphic units and an order‐of‐magnitude increase in sedimentation rates since the Middle Miocene corresponding with the onset of sedimentation dominated by mass transport deposits. ABSTRACT The Guyana Basin developed in an evolving tectonic setting, but a lack of subsurface data has ...
