Stratigraphical section through Lower Cambrian at Söderfjärden, Vaasa, western Finland [PDF]
Bulletin of the Geological Society of Finland, 1982 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
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2016 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 ...

Boreas, EarlyView.Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

Geophysical Prospecting, Volume 74, Issue 7, September 2026.ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract In deep bedrock fractures of the Fennoscandian shield, pyrite with “superheavy” δ34S values of up to 147‰ exists together with calcite. The extreme variability and 34S‐enrichment in pyrite indicate that microbial sulfate reduction (MSR) evolved to almost complete sulfate exhaustion in closed‐system microenvironments.

Boreas, Volume 55, Issue 3, Page 612-669, July 2026.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 ...
