Stratigraphical section through Lower Cambrian at Söderfjärden, Vaasa, western Finland [PDF]
The Lower Cambrian sedimentary rocks form a doughnut-shaped deposit on the bottom of the Söderfjärden depression. The sedimentary pile was first established and has now been penetrated by drilling.

Dynamic features of “Petrozavodsk” seismic station
The paper is devoted to the estimability and recordability of seismic events, namely the research of the noise power spectral density (PSD) and its diurnal variation around “Petrozavodsk” seismic station (PTRZ), located within the Onega structure of the ...

A critical discussion of competing models of the geodynamic nature (oceanic or continental subduction) and age (Meso-Neoarchean or Late Paleoproterozoic) of the eclogite facies metamorphism in the Belomorian eclogite province (BEP) is based on the ...

Geological-geophysical models of the crust for the White Sea region
The study of the White Sea region and the adjacent area aimed to model the structure of the crystalline portion of the crust at the contact of the northeastern slope of the Fennoscandian Shield and the Russian Plate.

We present a 25‐stage reconstruction of the ice‐flow pattern evolution of the Scandinavian Ice Sheet based on mapping and analysis of ~240 000 subglacial lineations and lineation fields across Norway, Sweden, Finland, and parts of NW Russia. Our reconstruction uses a glacial geomorphological inversion approach, in which we generated 611 individual ...

Evolution and Provenance of the Polish Rotliegend in the Southern Permian Basin
Abstract The Southern Permian Basin (SPB) has been extensively explored for ore deposits. However, a comprehensive evaluation of the remaining copper potential, specifically for sediment‐hosted stratiform copper system, remains lacking. This study applies goSPL, an open‐source landscape and stratigraphic evolution model, to reconstruct the Permian rift‐

Paleoproterozoic Metamorphism of the Archean Tuntsa Suite, Northern Fennoscandian Shield [PDF]
The Tuntsa Suite is a polymetamorphic Archean complex mainly consisting of metasedimentary gneisses. At least two strong metamorphic events can be distinguished in the area. The first took place at high temperatures in the Neoarchean at around 2.70–2.64 Ga, indicated by migmatisation and U-Pb ages of metamorphic zircon.

Increased Glacier Melt Across Millennia to Hours Enhances Erosion and Sediment Export Processes
Abstract Glacial erosion and sediment evacuation are key in shaping polar and mountain landscapes and influencing downstream ecological and social systems. The glacier dynamics and hydrology responsible for these processes are closely linked to hydrological and climatic (hydro‐climatic) conditions.
