Detrital input quantification in lacustrine petroleum systems: An example of the pre‐salt source rocks from the Lower Congo Basin (Congo)

The Depositional Record, 2021
This study describes an integrated workflow designed to quantify detrital input into lacustrine deposits in terms of regional extent and total organic carbon content.

Research on the sedimentary characteristics of organic matter in lacustrine mudrocks and their hydrocarbon generation potential based on palynofacies analysis: Eocene shahejie formation, dongying sag

Frontiers in Earth Science, 2022
Lacustrine mudrocks are important hydrocarbon source rocks due to their high contents of organic matter (OM). An accurate determination of the origins of OM in the rocks can contribute greatly to the identification of the sedimentary environment and the ...

Palynofacies and Sporomorph EcoGroups-based paleoecology implications for the Dalichai Formation, Andariyeh, central Alborz [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2020
The Dalichai Formation at the Andariyeh stratigraphic section in the northeast of Andariyeh village, central Alborz Mountains, was studied by using analyses of the Sporomorph EcoGroups (SEGs) data and associated plant communities and palynofacies in ...

The Hoanh Bo Trough‐a landward keyhole to the syn‐rift Late Eocene–Early Oligocene terrestrial succession of the northern Song Hong Basin (onshore north‐east Vietnam)

Geological Journal, Volume 57, Issue 10, Page 4216-4241, October 2022., 2022
The sedimentary pattern and interpretation of the Hoanh Bo Trough evolution match well with the rift initiation, rift development, and rift termination tectonic system tracts of the South China Sea and could be treated as a landward keyhole for the offshore basins of the northern Song Hong Basin.

A new stratigraphic framework for the Miocene – Lower Pliocene deposits offshore Scandinavia: A multiscale approach

Geological Journal, Volume 56, Issue 3, Page 1699-1725, March 2021., 2021
A multiscale stratigraphic framework (combined dinocyst stratigraphy, sequence stratigraphy, and seismic stratigraphy) for the Neogene succession in the Danish North Sea area is presented. Based on this framework, an updated stratigraphic subdivision of the more fragmentary Neogene succession in the well 6407/9‐5 (Norwegian Sea shelf), proposed as the ...

Paleoenvironment of the Cerro Negro Formation (Aptian, Early Cretaceous) of Snow Island, Antarctic Peninsula

Anais da Academia Brasileira de Ciências, 2022
A study of macro and microfacies, palynoflora and palynofacies of the non-marine Cerro Negro Formation at President Head Peninsula, Snow Island, northwest of the Antarctic Peninsula, was developed. Two assemblages were recognized: Palynofacies assemblage

Palynostratigraphy, Palynofacies, T-R Cycles and Paleoenvironments in the Middle Jurassic–Early Cretaceous Ramså Basin, Andøya, Northern Norway

Geosciences, 2021
Palynostratigraphy and palynofacies analyses are applied to identify transgressive-regressive sequences and changes in paleoenvironment through the Middle Jurassic–Early Cretaceous succession of the Ramså Basin on Andøya. The conglomerate, the succeeding
