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.

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 ...
