NEW CHRONOSTRATIC SCHEME OF SOUTH-EASTERN FENNOSCANDIA AND ITS USE IN THE PREPARATION OF SMALL-SCALE GEOLOGICAL MAPS OF THE PRECAMBRIAN REGIONS

Известия высших учебных заведений: Геология и разведка, 2017
A new chronostratic scheme of South-East (SE) Fennoscandia has been developed, based on the International Stratigraphie Scale, taking into account some elements of the Common Stratigraphic Scale of Russia and the regional stratigraphic scheme of the ...

New evidence of the Vuoksi River origin by geodynamic cataclysm [PDF]

Bulletin of the Geological Society of Finland, 2018
The territory of investigations is located in the SE periphery of the Fennoscandian Shield. It served as an arena of periodic significant restructuring of the hydrographic network associated with the filling and discharge of large late-glacial and ...

Geochemical and Isotopic Constraints on Long‐Lived Source Enrichment and Mantle Evolution in Paleoproterozoic Cratonic Lamprophyres

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The cratonic lithospheric mantle records complex metasomatic processes and is frequently tapped by alkaline magmatism, offering a unique opportunity to trace the progressive evolution of the mantle. In the present contribution, we investigate a newly identified calc‐alkaline lamprophyre field from the Neoarchean Jonnagiri Schist Belt, Eastern ...

Radiolysis and Fe‐Biotite Alteration: Questioning the Origin of H2‐Bearing Fluid Inclusions in the Yorke Peninsula Granites, South Australia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Multiple drillings in the Yorke Peninsula, South Australia, recently confirmed the presence of natural hydrogen (H2) in shallow sedimentary units. While radiolysis and Fe‐oxidation in the basement are potential generation mechanisms, their respective contributions remain unconstrained.

Glaciation and regional groundwater flow in the Fennoscandian shield

Geofluids, 2012
AbstractRegional‐scale groundwater flow modeling of the Fennoscandian shield suggests that groundwater flow can be strongly affected by future climate change and glaciation. We considered variable‐density groundwater flow in a 1500‐km‐long and approximately 10‐km‐deep cross‐section through southern Sweden. Groundwater flow and shield brine transport in

Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages)—a review

Boreas, Volume 55, Issue 2, Page 282-307, April 2026.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Holocene subaqueous landslide dynamics in the Lake Siljan‐Orsasjön Basin, south‐central Sweden

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Subaqueous landslide areas studied by multibeam bathymetry, sub‐bottom profiling and sediment coring reveal complex stratigraphies, suggesting mass movement events starting close to the area's deglaciation and up to very recent times. Abstract The Siljan‐Orsasjön Basin in south‐central Sweden hosts two prominent lakes.

A Two‐Part Framework for Depth to Bedrock Prediction and Uncertainty Assessment in Sweden

European Journal of Soil Science, Volume 77, Issue 2, March–April 2026.
ABSTRACT Accurate mapping of depth to bedrock (DTB) in complex post‐glacial landscapes is challenging due to high spatial variability and the prevalence of bedrock outcrops, which introduce “structural zeros” that violate standard regression modelling assumptions.
