Subsurface Life on Earth as a Key to Unlock Extraterrestrial Mysteries. [PDF]
Microb BiotechnolThis paper discusses current research on subsurface microbiology. Exploring Earth's deep and extreme subsurface environments provides critical insights into life's limits and adaptability. Subsurface exploration is not only vital for understanding the origins and limits of life on Earth, but also crucial for informing future missions in the search for ...

Paleolatitude and cause of the Svecokarelian orogeny [PDF]
Bulletin of the Geological Society of Finland, 1974 Paleomagnetic data suggest a paleolatitude of 22°N for the Fennoscandian protocontinent during the Svecokarelian orogeny. This is lower than that of the Canadian shield during the same period.

Distribution of culturable microorganisms in Fennoscandian Shield groundwater [PDF]
FEMS Microbiology Ecology, 2002 Microbial populations in 16 groundwater samples from six Fennoscandian Shield sites in Finland and Sweden were investigated. The average total cell number was 3.7x10(5) cells ml(-1), and there was no change in the mean of the total cell numbers to a depth of 1390 m.

Timing of Palaeoproterozoic crustal shearing in the central Fennoscandian Shield according to U-Pb data from associated granitoids, Finland [PDF]
Bulletin of the Geological Society of Finland, 2001 Granitoids in the Finnish part of the Fennoscandian Shield were created by numerous Archaean and Palaeoproterozoic tectonic events. Late phases of Palaeoproterozoic, Svecokarelian deformation created ductile, crustal-scale shear zones, of which the N-S ...

Growth of the Archean sialic crust as revealed by zircon in the TTGs in eastern Finland [PDF]
Bulletin of the Geological Society of Finland, 2021 U–Pb age determinations on zircon from granitoids in the Archean of eastern Finland were conducted using the SIMS, LA-ICP-MS and TIMS techniques, with an emphasis on low-HREE granitoids.

Fault systems in multiply deformed regions of Eurasia
Russian Journal of Earth Sciences, 2023 We have studied the orogenic fragile deformation of the upper Earth’s crust of several areas of the Eurasian continent, where deformations have occurred many times – in the Tian Shan and Altai-Sayan regions of the Central Asian Paleozoic Fold Belt and in

Vanadium Mineralization in the Kola Region, Fennoscandian Shield [PDF]
Minerals, 2018 In the northern Fennoscandian Shield, vanadium mineralization occurs in the Paleoproterozoic Pechenga–Imandra-Varzuga (PIV) riftogenic structure. It is localized in sulfide ores hosted by sheared basic and ultrabasic metavolcanics in the Pyrrhotite Ravine and Bragino areas and was formed at the latest stages of the Lapland–Kola orogeny 1.90–1.86 Ga ago.

Timing of syn-orogenic, high-grade transtensional shear zone formation in the West Uusimaa Complex, Finland [PDF]
Bulletin of the Geological Society of Finland, 2022 We present zircon and titanite U-Pb ages from granulite-facies transtensional shear zones and a greenschist facies strike-slip shear zone in the Karkkila-Vihti area, West Uusimaa. The zircon rim and titanite ages of c.
