Paleoenvironmental Changes Based on Palynofacies Analysis of the Albian - Maastrichtian Interval of the Pernambuco Basin, Northeast Brazil

Anuário do Instituto de Geociências - UFRJ, 2018
In order to infer paleoenvironmental changes for the Cretaceous of the Pernambuco Basin, 26 samples collected in the IATE 1-LABIO-PE3 well were analyzed. The study includes the Albian-Maastrichtian interval, which represent the Cabo, Estiva, Itamaracá and Gramame formations.

Evolution and architecture of an exhumed ocean‐facing coarse‐grained submarine canyon fill, Baja California, Mexico

Sedimentology, Volume 72, Issue 1, Page 189-226, January 2025.
ABSTRACT Present day submarine canyons are active conduits for the transfer of large volumes of sediment, carbon and pollutants from continents to oceans. However, the evolution of submarine canyons over geological timescales remains poorly understood due to their erosional nature and low preservation potential. The Late Cretaceous Punta Baja Formation

Hydrocarbon‐derived thrombolites from the Outer Carpathians (Lower Cretaceous, Poland)

Sedimentology, Volume 71, Issue 7, Page 2183-2209, December 2024.
Abstract Shallow marine thrombolites from a newly discovered Lower Cretaceous cold seep in the Outer Carpathians (Poland) were analysed in order to untangle the complex sedimentological and biogeochemical processes involved in their formation and their diagenetic modifications.

Palynofacies Analyses of Fox Bay Formation (Devonian), Falkland Islands [PDF]

, 2019
The Falkland Islands are an archipelago consisting two main islands (West and East) that show contrasts in their sedimentary history. The palynofacies analysis was applied as tool for reconstructing the history of sedimentary organic matter deposition ...

The latest Jurassic–earliest Cretaceous climate and oceanographic changes in the Western Tethys: The Transdanubian Range (Hungary) perspective

Sedimentology, Volume 71, Issue 6, Page 1843-1872, October 2024.
Abstract The Jurassic/Cretaceous transition was characterized by several distinct palaeoenvironmental processes and events, amongst which some of the best known are the late Tithonian–early Berriasian aridization and the late Berriasian tectonic reactivation in the Neotethyan Collision Belt.

Palynofacies classification of submarine fan depositional environments: Outcrop examples from the Marnoso-Arenacea Formation, Italy [PDF]

, 2017
Basin floor fans contain some of the largest deep-water hydrocarbon accumulations discovered, however they also demonstrate extremely complex stratigraphic architecture, understanding of which is crucial for maximum recovery. Here we develop a new method,

Hydrocarbon Generation Potential of the Campano-Maastrichtian Dark Mudstone Lithofacies, Benin Flank, South West Anambra Basin, Nigeria

Journal of Applied Sciences and Environmental Management, 2020
The dark mudstone lithofacies of Mamu Formation was deposited during the Campano-Maastrichtian flooding episode. It is laterally heterogeneous, and has been subdivided into marsh, bay and central basin subenvironments in order of proximality.
