Research on the sedimentary characteristics of organic matter in lacustrine mudrocks and their hydrocarbon generation potential based on palynofacies analysis: Eocene shahejie formation, dongying sag

Frontiers in Earth Science, 2022
Lacustrine mudrocks are important hydrocarbon source rocks due to their high contents of organic matter (OM). An accurate determination of the origins of OM in the rocks can contribute greatly to the identification of the sedimentary environment and the ...

Multi‐Parameter Investigation of Cretaceous to Palaeocene Sedimentary Sequences in the Anambra and Niger Delta Basins, Nigeria: Organic Matter Characterisation, Palynofacies and Implications for Palaeoclimate and Sea‐Level Changes

Geological Journal, Volume 60, Issue 1, Page 196-222, January 2025.
The study examines Cretaceous to Palaeogene sedimentary sequences in the Anambra Basin, part of West African rift basins, utilising geochemical and palynological interpretations to understand organic matter accumulation. Palynofacies and geochemical data indicate a predominantly warm and humid tropical climate during a time of widespread marine ...

Evolution and architecture of an exhumed ocean‐facing coarse‐grained submarine canyon fill, Baja California, Mexico

Sedimentology, Volume 72, Issue 1, Page 189-226, January 2025.
ABSTRACT Present day submarine canyons are active conduits for the transfer of large volumes of sediment, carbon and pollutants from continents to oceans. However, the evolution of submarine canyons over geological timescales remains poorly understood due to their erosional nature and low preservation potential. The Late Cretaceous Punta Baja Formation

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

Facies, 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 Upper Cretaceous carbonate-siliciclastic sediments of southern Poland.

Occurrence of photosynthetic microbial mats in a Lower Cretaceous black shale (central Italy): a shallow-water deposit [PDF]

, 2018
Cretaceous oceanic anoxic events (OAEs) were periods of high organic carbon burial corresponding to intervals with excellent organic matter (OM) preservation.

Silicification and organic matter preservation in the Anisian Muschelkalk: Implications for the basin dynamics of the central European Muschelkalk Sea [PDF]

, 2017
Anisian Muschelkalk carbonates of the southern Germanic Basin containing silicified ooidal grainstone are interpreted as evidence of changing pH conditions triggered by increased bioproductivity (marine phytoplankton) and terrestrial input of plant ...

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

Sedimentology, 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

Journal 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.

Palynofacies Analysis and Hydrocarbon Generation Potential of the Tithonian-Beriassian Chia Gara Formation from Selected Wells in Ajil, Hamrin, and Tikrit Oilfields, Northern Iraq [PDF]

Kirkuk Journal of Science, 2018
The recovered sedimentary organic matter from the Tithonian-Berriasian Chia Gara Formation was studied from three selected wells of Ajil-12 (Aj-12), Hamrin-1 (Hr-1), and Tikrit-3 (Tk-3) in Northern Iraq.
