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 ...
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 ...
Geochemistry of felsic, mafic and ultramafic rocks in the suprasubduction zone Mawat ophiolite, Northeast Iraq
(Turun yliopisto, 2021-11-19)
The Mawat ophiolite is a remnant from the Neotethyan oceanic lithosphere exposed within the Zagros Suture Zone, northeastern Iraq. This thesis focuses on the evolution of the mantlederived magma and their temporally and ...
