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

open access: yesSedimentology, 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.

Evidence for Low‐Pressure Crustal Anatexis During the Northeast Atlantic Break‐Up

open access: yesGeochemistry, Geophysics, Geosystems, Volume 25, Issue 7, July 2024.
Abstract While basaltic volcanism is dominant during rifting and continental breakup, felsic magmatism may be a significant component of some rift margins. During International Ocean Discovery Program (IODP) Expedition 396 on the continental margin of Norway, a graphite‐garnet‐cordierite bearing dacitic unit (the Mimir dacite) was recovered in two ...

Palynofacies analysis of Ida-4 well, Niger Delta Basin, Nigeria

open access: yesGeology, Geophysics & Environment, 2019
Palynofacies analyses of the strata penetrated by Ida-4 wells were carried out with the aim of studying the stratigraphic sequence penetrated by the well in order to establish palynostratigraphic zones, relative age and the paleoenvironment of deposition. Fifty ditch cutting samples within the interval of 2179–3523 m were analyzed.

Palynofacies analysis – principles and application for paleoenvironmental studies: implications from Bulgaria

open access: yesReview of the Bulgarian Geological Society, 2021
The use of palynofacies analysis has been steadily increasing during the last decades. This stems from both commercial interests (i.e., hydrocarbon exploration) and academic research of past environments and studies of the global climate changes that took place during the Phanerozoic.

The Carboniferous-Permian transition in Arunachal Pradesh, North East India: A palynological and palynofacies study

open access: yesEarth History and Biodiversity
Palynological and palynofacies analyses were carried out from an outcrop of the Bichom Formation located in Arunachal Pradesh, North-East India. The age of the Bichom Formation at this locality is inferred based on palynological investigation and ...
