Broadband seismic data acquisition and processing of iron oxide deposits in Blötberget, Sweden

open access: yesGeophysical Prospecting, Volume 73, Issue 1, Page 80-95, January 2025.
Abstract In June 2022, an innovative seismic survey was conducted in Blötberget, central Sweden, to evaluate the effectiveness of employing both a broadband seismic source and broadband receivers for mineral exploration in a challenging hardrock setting. The Blötberget mine hosts high‐quality iron oxides, predominantly magnetite and hematite, sometimes

Structural setting of late Svecofennian granites and pegmatites in Uusimaa Belt, SW Finland : age constraints and implications for crustal evolution

open access: yes, 2008
Complex late Svecofennian deformation patterns and voluminous granitic magmatism at ˜1.85-1.80 Ga characterise the Palaeoproterozoic Uusimaa Belt in SW Finland.

A COMBINED MODEL OF THE DIAPIRIC AND COLLISIONAL FORMATION MECHANISM OF THE PALEOPROTEROZOIC GRANITE-MIGMATITE-GNEISS DOMES OF THE SVECOFENNIAN BELT

open access: yesГеодинамика и тектонофизика, 2023
Geological examples of the development of thermal dome structures in the Svecofennian belt demonstrate the relationship between plutonic and metamorphic events and metamorphic strengthening towards the core parts of the structures.

The Upper Devonian to Lower Carboniferous Billefjorden Group on Bjørnøya, Svalbard, and Its North‐Eastern Greenlandic Provenance

open access: yesBasin 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.

New aspects to the geology of the Outokumpu region [PDF]

open access: yesBulletin 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 ...

Footprint of the Baltic Ice Stream: geomorphic evidence for shifting ice stream pathways

open access: yesBoreas, 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 ...

Thermal and hydrothermal influence of rapakivi igneous activity on late-Svecofennian granites in southeastern Finland. [PDF]

open access: yes, 2017
The recent discovery of polymetallic vein mineralizations around the Sarvlaxviken Bay (west-ernmost part of the Wiborg Batholith, SE Finland) has challenged the common assumption that Finnish rapakivi granites are metal-infertile and encouraged further ...

Seismotomography of the East European platform: a three-dimensional P-velocity model of the mantle near Fennoscandia. Part II

open access: yesГеофизический журнал, 2010
This paper is an extension of a set of works on seismic tomography of East European platform. A velocity pattern given corresponds to the mantle under Fenno-Scandian shield as a northwestern part of EEP.
