Methods in Paleopalynology and Palynostratigraphy
2017Because 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 ...

Microscopic Fungal Remains and Cenozoic Palynostratigraphy
Proceedings of the Annual Meeting. American Association of Stratigraphic Palynologists, 1976Abstract 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 ...

Mid Tertiary palynostratigraphy of Thailand
Journal of Southeast Asian Earth Sciences, 1990Abstract 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 ...

Late‐Glacial radiocarbon‐ and palynostratigraphy on the Swiss Plateau
Boreas, 1989A detailed late‐glacial radiocarbon stratigraphy for the Swiss Plateau has been established on the basis of over 90 accelerator14C dates on terrestrial plant macrofossils. Two plateaux of constant.,14C age were observed, occurring at 12,700 B.P. and at 10,000 B.P. The consequences of these plateaux for palaeo‐ecological investigations are threefold: (1)

Palynostratigraphy of the Upper Cretaceous in Hungary
Cretaceous Research, 1993Abstract Within the territory of Hungary four sedimentologically different sequences can be distinguished in the Senonian: the Transdanubian Central Range, the 'Gosau', the flysch and the southern Great Hungarian Plain. The most continuous Central Range sedimentary succession can be referred, on the basis of palynology, to the Upper Sanionian-Upper ...
