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

open access: yesAnais 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

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)

open access: yesGeological 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

open access: yesGeological 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 ...

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

open access: yesThe Depositional Record, Volume 7, Issue 1, Page 147-171, February 2021., 2021
The aim of this study was to propose an integrated workflow to quantify detrital input into autochthonous lacustrine deposits in terms of regional extent and total organic carbon (TOC) content. This workflow includes (a) organic geochemical data such as Rock Eval data together with quantitative palynofacies assessment and (b) palaeogeographical maps ...

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

open access: yesGeosciences, 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

Quantitative Biofacies Analysis to Identify Relationships and Refine Controls on Paleosol Development, Prince Creek Formation, North Slope Alaska, USA

open access: yesGeosciences, 2021
Late Cretaceous coastal plain deposits of the Prince Creek Formation (PCF) offer a rare glimpse into an ancient, high-latitude, arctic greenhouse ecosystem for which there is no modern analog.

Palynofacies, palaeoenvironments and petroleum [PDF]

open access: yesJournal of Micropalaeontology, 1982
Abstract. During the past decade, transmitted light microscopy of dispersed organic particles has become an important tool for assessing the petroleum potential of sedimentary basins. The main components of palynofacies and the colours of the microfossils preserved therein are widely used in the oil industry to aid the determination of organic ...

PALYNOFACIES AND SEDIMENTOLOGY OF HB-001 WELL

open access: yesMalaysian Journal of Geosciences, 2023
The palynofacies and sedimentological analyses of the sedimentary succession of the HB-001 well were carried out to establish biozones and the palaeodepositional environment. Ninety-six samples of ditch cutting within intervals of depth of 1250 -4011 m were analyzed. Most of the previous researchers established biozones with alpha-numeric method.

Multiple early Eocene carbon isotope excursions associated with environmental changes in the Dieppe-Hampshire Basin (NW Europe)

open access: yesBSGF - Earth Sciences Bulletin, 2020
The early Eocene experienced a series of short-lived global warming events, known as hyperthermals, associated with negative carbon isotope excursions (CIE).
