Age of the Ordovician sedimentary succession in Lumparn Bay, Åland Islands, Finland [PDF]
Estonian Journal of Earth Sciences, 2023 Depression of the ancient Lumparn meteorite impact structure in the à land Islands is partly infilled with the lower Palaeozoic sediments, lying presently below sea level. The Cambrian and Ordovician sedimentary cover is distributed in the area of 15 km2,

Oxygen isotope compositions of conodonts – analytical challenges of in situ SIMS studies [PDF]
Estonian Journal of Earth Sciences, 2023 Reliable deep-time environmental and climate reconstructions are needed to understand the drivers of Earthâs system evolution over geological time. Palaeozoic temperature estimates, including reconstructions of the climate change through the Ordovician,

Middle–Late Ordovician organic- walled phytoplankton from Sweden: diversity and early radiation [PDF]
Estonian Journal of Earth Sciences, 2023 The Borenshult-1 core, drilled in the vicinity of Motala, east of Lake Vättern in south central Sweden, comprises a well-dated and nearly complete succession of marine marly carbonates deposited relatively close to land. The 34 core samples analyzed for

Terra Nova, 2023 AbstractLate Ediacaran opening of the Iapetus Ocean is typically considered to reflect separation of Baltica and Laurentia during final breakup of the Rodinia supercontinent, with subsequent closure during the Caledonian Orogeny. However, evidence of the pre‐opening juxtaposition of Baltica and Laurentia is limited to purportedly similar apparent polar

Provenance shift in Cambrian mid-Baltica: detrital zircon chronology of Ediacaran–Cambrian sandstones in Estonia [PDF]
Estonian Journal of Earth Sciences, 2014 In order to clarify the tectono-sedimentary history of Paleozoic Baltica, age spectra of detrital zircon grains from the Ediacaran (Kotlin Regional Stage) and Lower Cambrian sandstones (lowermost Lontova and Lükati formations) in western Estonia in ...

The appearance of Rosenella (stromatoporoid sponge) in Baltica: new species from the Pirgu Stage (Katian, Upper Ordovician) of Estonia [PDF]
Estonian Journal of Earth SciencesThe Katian Age, part of the Late Ordovician Epoch, was a period of significant stromatoporoid diversification. However, their fossil record is often less continuous, hindering our understanding of their diversity and diversification.
