Thermomechanical lithospheric structure of the central Fennoscandian Shield
Physics of the Earth and Planetary Interiors, 2000Abstract The deep seismic sounding (DSS) profiles BALTIC, including its southern continuation, the Sovetsk–Kohtla–Jarve (SKJ) profile, SVEKA, the northern part of BABEL, POLAR, FENNIA and Pechenga–Kovdor–Kostomuksha, were used in studying the present-day thermomechanical structure of the central Fennoscandian Shield.

Velocity heterogeneities in the lithosphere of the Fennoscandian (Baltic) shield
Doklady Earth Sciences, 201464 The velocity structure of the lithosphere in the Fennoscandian Shield is of great interest for two main reasons: classical problems in the study of the Earth’s deep structure and the problems in the definition of promising zones which display their mineralogenic features.

Palaeomagnetism of the Sveconorwegian mobile belt of the Fennoscandian Shield
Precambrian Research, 1984Abstract The Sveconorwegian belt is a broad terrain in the south western sector of the Fennoscandian Shield subjected to thermal activation, widespread intrusion and limited tectonic activity between ca. 1100 and 950 Ma, and magnetised during slow uplift and cooling following these mobile events. This study comprises a palaeomagnetic investigation of

Evidence for bacterially generated hydrocarbon gas in Canadian shield and fennoscandian shield rocks
Geochimica et Cosmochimica Acta, 1993Hydrocarbon-rich gases found in crystalline rocks on the Canadian and Fennoscandian shields are isotopically and compositionally similar, suggesting that such gases are a characteristic feature of Precambrian Shield rocks. Gases occure in association with saline groundwaters and brines in pressurized “pockets” formed by sealed fracture systems within ...

Paleomagnetism in the Neoarchean polyphase Panozero intrusion in the Fennoscandian Shield
Moscow University Geology Bulletin, 2009Paleomagnetic research of the Neoarchean polyphase Panozero sanukitoid massif of the Fennoscandian Shield was performed. Paleomagnetic studies of three rock associations of the massif was used to obtain the paleomagnetic pole Φ = −10.2°C Λ = 226.1°C, dp = 4.9°, dm = 3.5° ϕm = − 36.1°.

Deep life in Fennoscandian Shield
2014The continental earth crust contains regions of very different age and composition including crystalline rocks, metamorphic systems, sedimentary basins and organic deposits, and magmatic intrusions. Throughout the crust, fluids are the principal agents in transporting and focusing Earth's energy and mineral resources.

Electrical conductivity distribution of the lithosphere in the central Fennoscandian Shield
Precambrian Research, 1993Abstract Geoelectric information on the crustal structures of the central Fennoscandian Shield consists of magnetovariational (MV) and magnetotelluric (MT) data. MV-data are obtained from magnetometer arrays devised to map lateral variations of subsurface resistivity; MT-data are obtained from soundings yielding knowledge on vertical resistivity ...

Thermal history of impact melt rocks in the Fennoscandian shield
Contributions to Mineralogy and Petrology, 1975Shock-melted rocks from the Fennoscandian shield commonly contain fragments of quartz which appear to represent paramorphs of quartz after lechatelierite and, therefore indicate very high melt temperatures, at or above 1700 °C.
