Evolution of the Svecofennian Bedrock in Southern Finland - Spatial and temporal changes in the mantle-derived magmatism and mantle-crust interaction
(Turun yliopisto, 2021-06-23)
The Svecofennian orogen in the central Fennoscandian Shield was formed between 1.96–1.77 Ga. This study focuses on characterizing the temporal and spatial changes of the mantle derived and related magmas in southern Finland ...
Tonni- ja pitoisuusmallit Suomen karbonatiitti- ja alkalikivi-isäntäisille REE- ja P-esiintymille
(Turun yliopisto, 2016-12-14)
Tutkimuksen tarkoitus oli luoda tonni- ja pitoisuusmallit Suomen karbonatiitti- ja alkalikivi-isäntäisille REE- ja P-esiintymille. Tämä tutkimus oli pohjatyötä Geologian tutkimuskeskuksen ”Mineraaliset raaka-aineet ...

Thermal and hydrothermal influence of rapakivi igneous activity on late-Svecofennian granites in southeastern Finland.
(Turun yliopisto, 2017-03-15)
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 ...
Genesis and Emplacement of Carbonatites and Lamprophyres in the Svecofennian Domain
(Turun yliopistoAnnales Universitatis Turkuensis A II 252, 2010-08-31)
A small carbonatite dyke swarm has been identified at Naantali, southwest Finland. Several swarms of shoshonitic lamprophyres are also known along the Archean-Proterozoic boundary in eastern Finland and northwest Russia. ...
Genesis and Evolution of Brittle Structures In Southwestern Finland and Western South Africa. Insights into Fault Reactivation, Fluid Flow and Structural Maturity in Precambrian Cratons
(Turun yliopistoAnnales Universitatis Turkuensis A II 300, 2015-04-10)
The bedrock of old crystalline cratons is characteristically saturated with brittle structures formed during successive superimposed episodes of deformation and under varying stress regimes. As a result, the crust effectively ...
Palaeoproterozoic crustal evolution in SW Fennoscandia, Baltic Sea region
(Turun yliopisto, 2021-08-20)
ABSTRACT
The Palaeoproterozoic crustal evolution of the Fennoscandian Shield involves significant crustal growth with a marked zonation from older rocks in the northeast to younger rocks in the southwest. Following the ...
Shear zones and structural analysis of the Loimaa area, SW Finland
(2019-06-18)
The study area is located in the western part of the Häme belt, where deformation has partitioned into folded- and sheared domains. The N-S and the ENE-WSW striking shear zones form the most prominent structures. In areas ...
Geological, petrographic and geochemical evaluation of two Svecofennian ultramafic serpentinized bodies in Pernaja, SE Finland
(2019-02-05)
When mafic-ultramafic rocks get encountered with fluids in conditions of low temperature and pressure, they are subject to an alteration form known as serpentinization. It is a process which causes several changes in the ...
Geochemistry, age and structural character of the Au-hosting Uunimäki gabbro, SW Finland
(2019-03-18)
The western Häme Belt hosts several gold deposits, including the Uunimäki deposit, which is hosted by a gabbro. There are three main goals in this study: (i) age determination of the Uunimäki gabbro, (ii) geochemical ...
