Palynology of a terrestrial coal-bearing series across the Triassic/Jurassic boundary (Mecsek Mts, Hungary) [PDF]

open access: yes, 2008
Palynology and palynofacies patterns of terrestrial Triassic/Jurassic boundary series of the South Hungarian Mecsek Mountains were studied in search of paleoenvironmental and vegetation changes and climatic signatures related to one of the major mass ...

Hydrocarbon‐derived thrombolites from the Outer Carpathians (Lower Cretaceous, Poland)

open access: yesSedimentology, Volume 71, Issue 7, Page 2183-2209, December 2024.
Abstract Shallow marine thrombolites from a newly discovered Lower Cretaceous cold seep in the Outer Carpathians (Poland) were analysed in order to untangle the complex sedimentological and biogeochemical processes involved in their formation and their diagenetic modifications.

Hydrocarbon Generation Potential of the Campano-Maastrichtian Dark Mudstone Lithofacies, Benin Flank, South West Anambra Basin, Nigeria

open access: yesJournal of Applied Sciences and Environmental Management, 2020
The dark mudstone lithofacies of Mamu Formation was deposited during the Campano-Maastrichtian flooding episode. It is laterally heterogeneous, and has been subdivided into marsh, bay and central basin subenvironments in order of proximality.

Maastrichtian island in the central European Basin—new data inferred from palynofacies analysis and inoceramid stratigraphy

open access: yesFacies, 2017
The palynological study and palynofacies analysis supported by size analysis of opaque phytoclasts and diversity indexes for particulate organic matter in stratigraphically well-constrained (inoceramid biostratigraphy) sections is applied in monotonous ...

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.

Foraminifera, Thecamoebians and Palynomorphs as Hydrodynamic Indicators in Araguari Estuary, Amazonian Coast, Amapá State – Brazil [PDF]

open access: yes, 2010
The Araguari estuarine dynamics is singular among traditional models of estuaries under tidal regime due to influence of macrotidal and tidal bore. In order to establish estuarine zones in Araguari according foraminifera, thecamoebians, paliynomorphs ...

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 ...

Petrographic and geochemical study of organic matter in surficial laminated sediments from an upwelling system (Mejillones del Sur Bay, Northern Chile).

open access: yes, 2004
A study of recent laminated sediments, accumulated in the oxygen minimum zone of Mejillones Bay (Northern Chile), shows that the organic matter is autochthonous and deposited under varying oceanographic conditions.
