Source potential and palynofacies of Late Jurassic “Lemeš facies”, Croatia
Organic Geochemistry, 2009Laminated limestone and calcareous shale outcrop samples from the Late Jurassic "Lemeš" facies (Croatia) were investigated to characterize their organic facies and palynofacies and their hydrocarbon generative potential.The results indicate that the organic-rich sediments of "Lemeš" facies were deposited within a relatively shallow marine environment ...

Palynofacies in a Sequence Stratigraphic Context
1995Sequence stratigraphy is a systematic way of looking at well established and familiar stratigraphic concepts such as eustatic cycles, transgression and regression, diachroneity, and progradation, retrogradation and aggradation. It represents a powerful methodology for modelling and analysing geometric, spatial and temporal patterns of sediment ...

Some Practical Aspects of Palynofacies Analysis
1995Much palynofacies work has been done as a secondary exercise within palynostratigraphic studies. Unfortunately, this often means that the samples were collected using a strategy that emphasizes standard sampling intervals and the selection of only those lithologies likely to be most productive in terms of palynomorph yield.

Palynofacies in upper cretaceous sediments of northern Siberia
Stratigraphy and Geological Correlation, 2010Different 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.

Palynofacies Analysis and Submicron Pore Modeling of Shale-Gas Plays
North American Unconventional Gas Conference and Exhibition, 2011Abstract 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 ...

Characterization of Mangrol lignite (Gujarat), India: Petrography, palynology, and palynofacies
International Journal of Coal Geology, 2013A multidisciplinary approach (petrographical, palynological and palynofacies) has been adopted to characterize and assess the depositional conditions of Eocene Mangrol lignite deposit from western India. The petrographic study reveals that the lignite is composed predominantly of huminite macerals produced from a woody forest.

High-resolution palynofacies investigation of Kimmeridgian sedimentary cycles
Geological Society, London, Special Publications, 1995Abstract 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.

Palynofacies and salinity in the Purbeck and Wealden of southern England
1982Many 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.

Orbital forcing of palynofacies in the Jurassic of France and the United Kingdom
Geology, 1999Palynofacies analysis of marine Jurassic sedimentary successions in France and the United Kingdom demonstrates the pervasiveness of regular cycles in qualitative and quantitative aspects of the microscopic particulate organic content of the rocks, especially that part which is ignored during routine palynology.

Woodbine Palynofacies--Their Relationship to Tuscaloosa of Gulf Coast: ABSTRACT
AAPG Bulletin, 1985A 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 ...
