Boreas, Volume 51, Issue 2, Page 496-516, April 2022., 2022 We present a new chironomid record from southern Germany that covers the mid‐Eemian to the end of the first Würmian stadial (roughly 125‐105 ka) and also parts of the late Rissian glaciation and early Brörup interstadial of the early Würmian glaciation.

American Journal of Botany, Volume 108, Issue 8, Page 1500-1524, August 2021., 2021 Abstract Premise The Fagaceae comprise around 1000 tree species in the Northern Hemisphere. Despite an extensive fossil pollen record, reconstructing biogeographic patterns is hampered because it is difficult to achieve good taxonomic resolution with light microscopy alone.

Basin Research, Volume 33, Issue 2, Page 1546-1579, April 2021., 2021 Abstract The Greater Barents Sea Basin (GBSB) in Arctic Russia and Norway is an intracratonic basin that accommodated an enormous amount of sediment during the Triassic. These deposits are up to 4.5 km thick over an area 2,500,000 km2, and consist of marine mudstones and mudstone‐rich fluvio‐deltaic topsets with sandstone‐dominated fluvial channels ...

A palynostratigraphic classification of the Westphalian of the southern North Sea carboniferous basin. [PDF]
, 1993 Based upon the examination of the palynostratigraphy of 28 well sections and 6 multi-well studies, the Westphalian sequences in the Southern North Sea Carboniferous Basin are divided into 7 biozones and 12 sub-biozones.

The sedimentary sequence from the Lake Ķūži outcrop, central Latvia: implications for late glacial stratigraphy [PDF]
Estonian Journal of Earth Sciences, 2011 Sediment samples from an outcrop in the near-shore area of Lake Ķūži (Vidzeme Heights, Central Latvia) were investigated using palaeobotanical (pollen and macrofossil analysis) and lithological (grain-size analysis) methods and accelerator mass ...

Late Jurassic-Early Cretaceous palynostratigraphy and palaeoclimate in the Andigama Basin, Sri Lanka
Journal of Asian Earth Sciences: X, 2021 Sri Lanka consists of only ten percent of sedimentary rocks, and high-grade metamorphic rocks underlie the rest. Most of these sedimentary terrains are post-Gondwanic and such formations help to understand the geological history of the island.
