Sedimentology, Palynofacies, and Hydrocarbon Potential of the Early Cretaceous Sarmord Formation from Khabbaz and Kirkuk Oil Fields, Northern Iraq

Iraqi Geological Journal, 2023
The Early Cretaceous Sarmord Formation of northern Iraq has been studied from two subsurface sections, Kirkuk Oil Field (well K-229) and Khabbaz Oil Field (well KH-14), through petrographic, palynolofacies and organic geochemical analyses.

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 ...

RECONSTRUCTING KUNGURIAN (CISURALIAN, PERMIAN) TERRESTRIAL ENVIRONMENTS WITHIN A MEGACALDERA IN THE SOUTHERN ALPS (N-ITALY) USING LITHOFACIES ANALYSIS, PALYNOLOGY AND STABLE CARBON ISOTOPES

Rivista Italiana di Paleontologia e Stratigrafia, 2023
During the Permian, climate experienced a change from icehouse to greenhouse conditions. Few multidisciplinary studies have investigated Kungurian (late Cisuralian) tropical terrestrial ecosystem and climate changes.

Termus shale of central Pahang, Malaysia: kerogen typing by palynofacies analysis

IOP Conference Series: Earth and Environmental Science, 2022
Abstract Palynofacies study has been done on selected samples fom the Late Jurassic – Early Cretaceous Termus Shale from Kuala Tahan, Jerantut-Jengka and Maran in Central Pahang to study its kerogen properties. Palynofacies study reveals distinct organic matter composition of different biological affinities from the samples where the ...

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

Geosciences, 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.

Integrating Palynofacies Analysis and Spore Coloration for Assessing Thermal Maturity and Hydrocarbon Potential in Cretaceous Rocks: Safir-N-2 Well, Egypt [PDF]

Egyptian Journal of Pure and Applied Science
Thirty-seven cutting samples from the lower upper Cretaceous succession of Safir-N-2 well, north Western Desert of Egypt, were processed palynologically to extract the particulate organic matter (POM). Two palynofacies associations (PFA-1 and PFA-2) were
