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 ...

Late‐Glacial radiocarbon‐ and palynostratigraphy on the Swiss Plateau

Boreas, 1989
A 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, 1993
Abstract 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 ...

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 in Phanerozoic and Precambrian Metamorphic Rocks

1992
A review is presented on the current state of palynological research in metamorphic rocks. Recent studies have shown that organic-walled microfossils may be structurally preserved in rocks of the greenschist facies and even those of the lower amphibolite facies from where they can be separated by a special maceration procedure.

Lower Jurassic palynostratigraphy of Eastern Siberia

Stratigraphy and Geological Correlation, 2017
This paper presents the results of a palynological study of the natural outcrops of the Lower and Middle Jurassic on the Kelimyar River (Outcrops 5, 6, 7, 14, and 16) and two boreholes, Middle-Nakynskaya and Ygyata-Tyungskaya 1, in Eastern Siberia. The Ukugut, Tyung, Motorchuna, Suntar, Kyrin, and Kelimyar formations were studied.

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).

Palynostratigraphy of the Stroud-Gloucester Trough, N.S.W.

Alcheringa: An Australasian Journal of Palaeontology, 1987
An investigation of spore-pollen assemblages from the Permian succession of the Stroud-Gloucester Trough, N.S.W., establishes that sedimentation began at the top of palynological zone Upper Stage 4 in the Dewrang Group. Deposition continued, without major break, through to the Gloucester Coal Measures, which are of lower Upper Stage 5 age.

Palynostratigraphy, Imperial Adgo F-28

1977
The biostratigraphy on Imperial Adgo F-28 consists of palynostratigraphy and zonation by Dr. Geoffrey Norris and a micropaleontological analysis by Dr. W. Braun. One hundred and six micropaleontological slides and 77 micropaleontological preparations from well cuttings provided by the Geological Survey of Canada were examined in detail.

Jurassic Palynostratigraphy of Offshore Eastern Canada

1977
Abstract The Scotian Shelf and Grand Banks, offshore southeastern Canada, cover approximately 175,000 square miles and extend over 850 miles from northeast to southwest. More than 100 exploratory wells drilled to date have encountered Lower Paleozoic to Recent sediments, which frequently contain rich and age diagnostic palynomorph assemblages.
