Terrigenous dissolved organic matter persists in the energy-limited deep groundwaters of the Fennoscandian Shield [PDF]
Nature Communications, 2022 Dissolved organic matter in the Fennoscandian Shield deep continental bedrock fracture waters of varying characteristics and ages carries a strong terrigenous signature, and only a small proportion of this potential energy source links to the deep ...

Energy efficiency and biological interactions define the core microbiome of deep oligotrophic groundwater [PDF]
Nature Communications, 2021 Ecological constraints on microbial niches in oligotrophic deep groundwaters remain elusive. This study provides support for the existence of a common core microbiome in two deep groundwater biomes of the Fennoscandian Shield using a genome-resolved ...

HETEROGENEOUS LITHOSPHERIC STRUCTURE OF THE FENNOSCANDIAN SHIELD: SEISMIC DATA
Геодинамика и тектонофизика, 2022 A generalization has been obtained based on the data for deep seismic studies on longitudinal DSS profiles (explosion seismology) and seismological evidence found for local and distant earthquakes (earthquake seismology) in the Fennoscandian Shield over ...

The Fennoscandian Shield deep terrestrial virosphere suggests slow motion ‘boom and burst’ cycles [PDF]
Communications Biology, 2021 Karin Holmfeldt et al. sequence metagenomes and metatranscriptomes of viruses in deep groundwaters down to 448 m below the surface. The results reveal ecological dynamics of viruses including slow motion ‘boom and burst’ cycles and a ‘kill the winner ...

Seismic model of the Earth's crust and upper mantle beneath the Fennoscandian Shield [PDF]
E3S Web of Conferences, 2023 Well-founded concepts of the crust and upper mantle structure of the Fennoscandian Shield were developed. Quantitative evidence for horizontal and vertical lithospheric heterogeneities was obtained.

Petrogenesis of the Paleoproterozoic Näränkävaara layered intrusion, northern Finland, Part II: U-Pb ID-TIMS age and Sm-Nd isotope systematics [PDF]
Bulletin of the Geological Society of Finland, 2022 Several mafic-ultramafic layered intrusions were emplaced in the NE Fennoscandian Shield during a magmatic episode at 2.44 Ga. The Paleoproterozoic Näränkävaara layered intrusion, northern Finland, is one of the largest ultramafic bodies in the ...
