The Applications of palynostratigraphy to the Devonian of Bolivia [PDF]
A continuous and unthrusted 1.2km section of latest Emsian to Frasnian sediments is exposed in the Rio Lajas at Bermejo, Santa Cruz Province, Bolivia. One hundred and forty-five samples were taken from this section to validate the cuttings-based Devonian subsurface palynostratigraphy.

Palynostratigraphy of the last interglacial/glacial cycle in Germany
Quaternary International, 1989Abstract The last interglacial/glacial cycle comprises the Eemian and the Weichselian (in the area of the Scandinavian Glaciation), respectively the Riss/Wurm and the Wurm (in southern Germany). Drastic changes of the vegetation have occurred several times during this period in Europe.

Upper Triassic–lowermost Jurassic palynology and palynostratigraphy: a review
Geological Society, London, Special Publications, 2010Abstract This review advances understanding of the palynostratigraphy of the Late Triassic–Early Jurassic by correlating the established palynozonations for the northern and southern hemispheres. Previous palynological studies have contributed greatly to our understanding of the biostratigraphy, paleoclimatology and paleogeography of the ...

Palynostratigraphy of the non-marine neogene in North Asia
Review of Palaeobotany and Palynology, 1986Abstract Palynological evidence leads to records of a number of floras and of vegetational evolution in West and Central Siberia and the northeastern area of the U.S.S.R., these may serve as a stratigraphic basis for correlation of the Neogene sediments in North Asia. In West Siberia there are six horizons and eighteen palynofloras, in the northeast

Palynostratigraphy and age of the Bhavnagar Lignite, Gujarat, India
Journal of Palaeosciences, 2000A good frequency of pollen and spore taxa are recovered during the palynological study of the Bhavnagar Lignite of Gujarat. Pollen assemblage consist of 66 genera and 85 species. Of these, eight genera and 12 species are of pteridophytic spores, one genus of gymnosperms and 57 genera and 74 species of angiosperms.

Palynostratigraphy of the late Ladinian and Carnian in the Southeastern Dolomites
Review of Palaeobotany and Palynology, 1988Abstract In the Late Ladinian and Carnian Cassian Formation, Cassian Dolomite and Raibl Group a qualitative and quantitative palynological investigation of 50 productive samples was carried out. Sixty taxa of pollen and spores were identified, one species is described as new.

Palynostratigraphy of the Triassic–Jurassic transition in southern Sweden
GFF, 2009Palynological samples from Upper Triassic and Lower Jurassic exposures and borehole sections of the Hoganas and Rya formations (Fm), NW Skane (Sweden), exhibit diverse and generally well-preserved palynomorph assemblages that can be divided into four miospore zones (from bottom to top): (1) the informal “Topmost upper Rhaetian” zone of Lund; (2) the ...

Palynostratigraphy of the murray basin, inland Southeastern Australia
Palynology, 1999Abstract To date, the only published comprehensive zonation for dating and correlating late Tertiary non‐marine sequences in Australia is that developed in the 1970s for the offshore Gippsland Basin on the extreme southeastern margin of the continent.

Permian palynostratigraphy of the Collie Basin, Western Australia
Review of Palaeobotany and Palynology, 1991Abstract The Collie Coal Measures and the underlying glacigene Stockton Formation are Permian lithologic units in the small, intracratonic Collie Basin situated near the western margin of the Yilgarn Craton in Western Australia. Palynological data were obtained from a number of cored boreholes and opencut mines.
