THE STRUCTURE OF LOW-VELOCITY ZONES IN THE MANTLE OF THE NORTHERN EUROPE
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015 The areas of low-velocity middle mantle shift into the transition zone are distinguished according to 3-d P-velocity model of the Fennoscandian shield mantle and its surroundings using Taylor approximation method.

Highly varying radiogenic heat production in Finland, Fennoscandian Shield [PDF]
Tectonophysics, 2019 Abstract Radiogenic heat production in Finland has been previously studied using airborne gamma-ray surveys and glacial till measurements alike. For the first time, this paper presents a detailed survey on the spatial variation in radiogenic heat production determined using outcrop samples obtained from all important lithologies of the country.

Microbialite Niches Across the Archean and Paleoproterozoic
Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.Abstract Changes in microbialite abundance during the Archean and Paleoproterozoic have been attributed to a variety of environmental and biological factors, yet past work looking at large‐scale patterns of microbialite abundance generally assumes shallow marine deposition rather than incorporating specific settings.

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract Ocean‐wide “Heinrich event” layers marked by weakly magnetic dolomitic ice‐rafted detritus (IRD) from the Hudson Bay region are a prominent signature of Laurentide Ice Sheet surges. Contrary to intuition, the Heinrich layers of the Ruddiman Belt IRD exhibit maxima of magnetic susceptibility. Building on IRD petrology and abundance in sediments

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract Eastern North America has hosted significant historical earthquakes, where seismicity clusters along tectonically inherited structures. Using the spherical finite‐element code CitcomSVE and fully 3D viscosity structure, we model the intraplate stress response to glacial isostatic adjustment (GIA) using ICE‐6G, both with and without low ...
