Methods in Paleopalynology and Palynostratigraphy

2017
Because of their small size and vast abundance in various types of sedimentary rocks, microfossils have found a multitude of applications in geology, especially regarding biostratigraphy, correlations, and paleoenvironmental analysis. Organic-walled microfossils such as pollen, spores, and various organic debris derived from terrestrial plants are ...

Mid Tertiary palynostratigraphy of Thailand

Journal of Southeast Asian Earth Sciences, 1990
Abstract Mid Tertiary palynological assemblages from fourteen stratigraphic sequences in nine basins in Thailand have been investigated. Special emphasis has been given to the spore-pollen record and its stratigraphic distribution. The basis for defining the zonations is the first or last appearance of key species including: Inaperturopollenites ...

Microscopic Fungal Remains and Cenozoic Palynostratigraphy

Proceedings of the Annual Meeting. American Association of Stratigraphic Palynologists, 1976
Abstract Fossil fungal spores and morphologically related material are common in Cenozoic sediments. Form genera and species are definable on morphologic character, including overall shape or symmetry, apertures, septa‐tion, and ornament. Sclerotia, hyphae from broken mycelia, and certain other cellular structures are accommodated by the Order Mycelia ...

Palaeogene palynostratigraphy of Simla Hills

Journal of Palaeosciences, 1981
The Palaeogene succession of Simla Hills consists of Subathu, Dagshai and Kasauli formations in ascending order of stratigraphy. The palynostratigraphical information developed from the marine sequence of Subathu sediments throws light on the dating potential of the assemblages and also on the distributional pattern of various palynomorphs.

Lower Toarcian palynostratigraphy of Pozzale, central Italy

Palynology, 1997
Abstract Palynological studies of the Lower Toarcian Pozzale section of central Italy (Tethyan Realm, Mediterranean province) have revealed significant differences between palynomorph assemblages from the Boreal and Tethyan realms and marked similarities between the two bioprovinces of the Tethyan Realm (Mediterranean and Sub‐Mediterranean).

Application of morphological lineages in Australian palynostratigraphy

Review of Palaeobotany and Palynology, 1990
Abstract In terms of biostratigraphic subdivision dorected towards chronostratigraphic correlation, the lineage zone is of major significance. With the application of palynostratigraphy to time correlation however, morphological lineages are little used.

Palynostratigraphy, Paleoclimate And Sequence Stratigraphic Analysis Of Emi-4 Well, Niger Delta, Nigeria

Global Journal of Geological Sciences
Palynostratigraphic, Paleoclimatic and Sequence Stratigraphic analyses were conducted in a section of Emi-4 well, Offshore Niger Delta to establish palynozones, relative age, paleodepositional setting and reconstruct paleoclimatic changes overtime within
