Late Neogene leaf assemblage from Bełchatów Lignite Mine (central Poland)

open access: yesActa Palaeobotanica, 2014
Leaf macroremains collected in the Bełchatów Lignite Mine (central Poland) were investigated. The fossil assemblage consists of leaves of Acer, Betula, Carpinus, Dicotylophyllum, Fagus, ?Magnolia, “Parrotia”, Pinus, Quercus, and Zelkova.

Using the fossil flora composition analysis for the reconstruction of vegetation and palaeoecological conditions during late glacial time in Karelia

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
The paper summarizes the results of pollen and macrofossil studies of late glacial deposits in Karelia, encompassing the Older Dryas, Allerod, and Younger Dryas – 12350–10300 14С yrs BP (14100–11900 cal. yrs BP).

Paleovegetation and paleoclimate in the Baise Basin during Oligocene

open access: yes地质科技通报, 2022
To reconstruct the palaeovegetation and palaeoclimate in the Baise Basin during the Oligocene, in this work, we analyzed sporopollen fossils from the Fuping Formation in this region.

Biomarker signatures of the Middle Jurassic coals from the Zhangjialiang mine in Dongsheng coalfield, North China: Implications for palaeoenvironment and palaeovegetation

open access: yesEnergy Exploration & Exploitation, 2023
The study on the Zhangjialiang No. 2 coal of Middle Jurassic Yan'an Formation in the northeastern Ordos Basin has been analyzed by gas chromatography-mass spectrometry (GC-MS) to determine geochemical characteristics and reconstruct palaeovegetation and ...

Evaluation of coupled ocean-atmosphere simulations of northern hemisphere extratropical climates in the mid-Holocene [PDF]

open access: yes, 2008
We have used the BIOME4 biogeography–biochemistry model and comparison with palaeovegetation data to evaluate the response of six ocean–atmosphere general circulation models to mid-Holocene changes in orbital forcing in the mid- to high-latitudes of the ...

What have we learnt from palaeoclimate simulations? [PDF]

open access: yes, 2016
There has been a gradual evolution in the way that palaeoclimate modelling and palaeoenvironmental data are used together to understand how the Earth System works, from an initial and largely descriptive phase through explicit hypothesis testing to ...

Vegetation dynamics in the Kostomuksha State Nature Reserve (Russia) and surroundings against changes in the natural environment during the Holocene

open access: yesNature Conservation Research: Заповедная наука, 2021
In the current situation of climate instability, research on the natural trends of vegetation development against global climate change is of high relevance, especially in areas once covered by the latest glaciation (Weichselian), and not altered ...

Role of tephra in dating Polynesian settlement and impact, New Zealand [PDF]

open access: yes, 2004
Tephrochronology in its original sense is the use of tephra layers as time-stratigraphic marker beds to establish numerical or relative ages (Lowe and Hunt, 2001).
