Palynofacies in upper cretaceous sediments of northern Siberia

Stratigraphy and Geological Correlation, 2010
Different palynomorph groups (spores and pollen of terrestrial plants, dinoflagellate cysts, prasinophytes, acritarchs, Zygnemataceae algae, and others) have been thoroughly studied to define major patterns in their distribution depending on the impact of different environmental factors and to establish their paleoecological characteristics.

The genesis and palynofacies characteristics of marine petroleum source rocks

Geological Society, London, Special Publications, 1987
SummaryThis paper attempts to demonstrate that the multi-disciplinary philosophy behind palynofacies investigations is of great value to the meaningful interpretation of the origins and palaeoenvironment of marine petroleum source rocks (MPSRs).The key control on the formation of MPSRs is identified as bottom water oxygenation (correlated with the ...

Palynofacies and salinity in the Purbeck and Wealden of southern England

1982
Many associations between components of palynological preparations and lithofacies in the Purbeck Beds and Wealden (uppermost Jurassic-Lower Cretaceous) of southern England have been recognised and are progressively being employed to aid the identification of depositional environments.

Palynofacies patterns of the Devonian of the Parnaíba Basin, Brazil: Paleoenvironmental implications

Journal of South American Earth Sciences, 2015
Abstract To help describe the paleoenvironmental interpretation of one the most extensive marine Devonian successions in Brazil, palynofacies analyses were conducted on 46 samples from the Itaim (Pragian–Givetian), Pimenteira (Givetian–Frasnian) and Cabecas (Famennian) formations of the Parnaiba Basin in north–central Brazil.

Woodbine Palynofacies--Their Relationship to Tuscaloosa of Gulf Coast: ABSTRACT

AAPG Bulletin, 1985
A recent palynologic study of the Texas Woodbine and comparison with the Gulf Coast Tuscaloosa have produced some interesting depositional models and increased our basic understanding of the relationship between these 2 petroliferous formations. Although age considerations and environments of deposition for the Woodbine were already determined from ...

Palynofacies Analysis and Submicron Pore Modeling of Shale-Gas Plays

North American Unconventional Gas Conference and Exhibition, 2011
Abstract The present study combines palynological applications with advanced microscopic techniques to characterize the Utica, Haynesville and Fayetteville shale-gas source rocks. This unprecedented approach could offer an alternative way to measure the total organic carbon (TOC) content using the 2D subsurface Scanning Electron ...

High-resolution palynofacies investigation of Kimmeridgian sedimentary cycles

Geological Society, London, Special Publications, 1995
Abstract Palynofacies analysis is used as a tool to investigate in detail the palaeoenvironmental variations through several sedimentary cycles in the Kimmeridge Clay of Kimmeridge Bay, Dorset, UK. Evidence is given of palaeoenvironmental variations within cycles corresponding to those expected for obliquity orbital forcing.

Development and multi-operator calibration of a standardised palynofacies analysis technique

2016
This report presents the results of a project to develop and test a standard approach and criteria for palynofacies analysis. Palynofacies analysis is a palynological method of sedimentary depositional facies recognition. It is the study of all particulate organic matter recovered in a palynological assemblage, and can be used to reconstruct ...

Use of palynofacies analysis in archaeopalynology

2017
Palynofacies analysis expands traditional archaeopalynology by including not only pollen, but also fungal spores, algal microfossils and a variety of microfossil debris. Archaeopalynology is the study of past human environments through pollen analysis.
