CH4‐He‐H2‐Rich Fluids Associated With the Intrusive Rocks of the Mid‐Continent Rift System in Minnesota (USA)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Several studies have shown that H2 and CH4 emissions are recorded within Precambrian areas, where the origin of gases has yet to be determined. The Mid‐Continent Rift (MCR) is an aborted rift aged from 1.1 Ga and composed of volcanic and (ultra)‐mafic rocks.

From Hydrocarbon to CO2 Storage: Unveiling the Potential of the Miocene Lille John Member in the Danish North Sea

open access: yesBasin Research, Volume 37, Issue 5, September–October 2025.
Depositional evolution of the upper Miocene complex. ABSTRACT To achieve net‐zero carbon emissions by 2050, gigatonnes of CO2 must be captured and stored in the subsurface. Screening and exploration of prospective storage sites have thus gained momentum in recent years.

Radioisotopic age constraints of the Cambrian Ritland impact structure, Norway

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 9, Page 2223-2238, September 2025.
Abstract Secondary ion mass spectrometry U‐Pb geochronology has been performed on zircon grains separated from impact melt rock from the 2.7 km‐in‐diameter Ritland impact structure, southwestern Norway. Scanning electron microscope‐based imaging techniques, including electron backscatter diffraction analysis, reveal various zircon grain microtextures ...

Scheme of mineral facies of metamorphic rocks and its application to the Fennoscandian shield with representative sites of orogenic gold mineralization

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
Our recent studies of metamorphism within the Fennoscandian (or Baltic) Shield area with representative sites of orogenic gold mineralization based on the scheme of mineral facies of metamorphic rocks introduced earlier inspired thorough revision of that

The urosozero greenstone structure (Fennoscandian shield): geology, composition, age and metamorphism of the volcanics

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2016
The results of detailed study of the Urosozero greenstone structure (northwestern part of the Vodlozero domain) of the Fennoscandian Shield are presented. The composition and the U-Pb zircon age of the volcanic rocks were studied. The Urosozero structure

Glaciation and regional groundwater flow in the Fennoscandian shield

open access: yesGeofluids, 2012
AbstractRegional‐scale groundwater flow modeling of the Fennoscandian shield suggests that groundwater flow can be strongly affected by future climate change and glaciation. We considered variable‐density groundwater flow in a 1500‐km‐long and approximately 10‐km‐deep cross‐section through southern Sweden. Groundwater flow and shield brine transport in
