Basin Research, Volume 36, Issue 6, November–December 2024.First detrital zircon provenance study of the Billefjorden Group on Bjørnøya, Svalbard. The East Greenland Caledonides formed a long‐lived source terrain in northeast Greenland. Syn‐sedimentary faulting, drainage shifts and changing fluvial styles have little influence on detrital zircon age spectrum.

Footprint of the Baltic Ice Stream: geomorphic evidence for shifting ice stream pathways
Boreas, Volume 53, Issue 1, Page 4-26, January 2024.The Baltic Ice Stream, a large fast‐flowing sector of the last Fennoscandian Ice Sheet that occupied the present‐day Baltic Sea basin, was first conceptualized in the earliest days of glacial geological research in Scandinavia. Landform and sedimentological evidence from the terrestrial margins support the concept and numerical ice‐sheet models ...

Crustal development in relation to granitic magmatism in regard to D/H partition between coexisting hornblende and biotite in the Svecofennian belt [PDF]
Bulletin of the Geological Society of Finland, 1993 Tie-lines in the σD-XFe diagram of hornblende and biotite in Japanese island arc granites give commonly a similar slope to that derived from the equation of Suzuoki-Epstein's experimental work (1976).

New aspects to the geology of the Outokumpu region [PDF]
Bulletin of the Geological Society of Finland, 1976 This study provides a general picture of the geology of the Outokumpu region with no attempt at being a detailed description. Special attention is paid to the areas occupied by Karelian and Prekarelian rocks and the location of the Outokumpu region in ...

New monazite U-Pb age constraints on the evolution of the Paleoproterozoic Vaasa granitoid batholith, western Finland [PDF]
Bulletin of the Geological Society of Finland, 2016 The Vaasa batholith, western Finland, is a large, peraluminous granitoid pluton that crystallized at 1.88–1.87 Ga during the culmination of the Svecofennian orogeny.
