Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Palynostratigraphy of the Dalichai Formation in Darjazin section, North of Semnan [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2018 The Dalichai Formation in Darjazin section in NE Semnan with a thickness of 631 meters consisting of an alternation of bulish-gray was studied.This formation overlies the Shemshak formation disconformity with conglomerate bed and it has gradually been ...

Terra Nova, Volume 35, Issue 6, Page 506-513, December 2023., 2023 Abstract “Doming–rifting–spreading” constitute the main phases of classical plate tectonics. The Middle–Upper Jurassic succession of East Greenland is interpreted as reflecting formation, deflation and onlap of a rift dome, similar to contemporaneous rift domes in the North Sea, Denmark and southern Sweden.

Boreas, Volume 51, Issue 4, Page 793-809, October 2022., 2022 To better understand the environmental variability during the Holsteinian interglacial, fauna of the palaeolake deposits at Ortel Królewski II, eastern Poland was investigated. The analysis covered the uppermost part of the profile, representing the so‐called pre‐optimal part of the Holsteinian interglacial (MIS 11c), namely the Taxus and Pinus‐Larix ...

Palynostratigraphy of the Middle Jurassic strata of central and eastern Alborz [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2018 Introduction In the geological history of Iran, the Mesozoic Era is of great significance since many important geological events occurred during this time interval. The tectonic and paleogeographic evolution of Iran during the Mesozoic controlled by the

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 ...

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.
