Deep seismic studies in the southeastern Fennoscandian Shield

open access: yesГеофизический журнал, 2015
The modern concept of the deep structure of the earth crust of the Ladoga-Bothnian zone, based on analysis and summing-up of all available information obtained in the last 35 years, is presented.

8: Precambrian geodynamics and ore formation: The Fennoscandian Shield [PDF]

open access: yesOre Geology Reviews, 2005
Abstract Compared with present-day global plate tectonics, Archaean and Palaeoproterozoic plate tectonics may have involved faster moving, hotter plates that accumulated less sediment and contained a thinner section of lithospheric mantle. This scenario also fits with the complex geodynamic evolution of the Fennoscandian Shield from 2.06 to 1.78 Ga ...

Formation mechanism of the Vaasa Batholith in the Fennoscandian shield: Petrographic and geochemical constraints [PDF]

open access: diamondBulletin of the Geological Society of Finland, 2012
The ~1.88 Ga Vaasa Batholith in western Finland is a large granitoid area (8 000 km2) with gradational contacts against the garnet- and cordierite-bearing diatexite and metatexite migmatites of the Pohjanmaa Belt.

Seismic model of the Earth's crust and upper mantle beneath the Fennoscandian Shield [PDF]

open access: yesE3S Web of Conferences, 2023
Well-founded concepts of the crust and upper mantle structure of the Fennoscandian Shield were developed. Quantitative evidence for horizontal and vertical lithospheric heterogeneities was obtained.

Precambrian geodynamics and ore formation : the Fennoscandian Shield

open access: green, 2006
The complex geodynamic evolution of the Fennoscandian Shield from 2.06 to 1.78 Ga involved rapid accretion of island arcs and several microcontinent-continent collisions in a complex array of orogens. With a few exceptions, all major ore deposits formed in specific tectonic settings between 2.06 and 1.78 Ga and thus a strong geodynamic control on ore ...
