Sedimentology, Volume 68, Issue 7, Page 3057-3101, December 2021., 2021 Abstract Sediments deposited by glacial meltwaters (for example, ice‐contact delta deposits) form permeable packages in the subsurface that can act as reservoirs for both water and hydrocarbons. They are also an important source of aggregate for the construction industry.

Zircon dating of the basalt and felsic dyke in Haveri, SW Finland [PDF]
Bulletin of the Geological Society of Finland, 2022 The E-MORB type Haveri basalt differs from the volcanic arc type rocks in the Tampere belt showing no subduction signature. It is considered to have formed in a marginal basin prior to the volcanic arc. We present here zircon U-Pb dating on two samples.

Terra Nova, Volume 33, Issue 5, Page 502-510, October 2021., 2021 Abstract Fault‐ and fracture‐hosted multi‐stage mineral assemblages that formed by fracture reactivation and fluid migration, constitute archives of the tectonic evolution of Precambrian cratons. Complex intergrowth patterns of these mineral records often hinder absolute dating of mineralization events for geological models.

The Salittu Formation in southwestern Finland, part I: Structure, age and stratigraphy [PDF]
Bulletin of the Geological Society of Finland, 2016 Because of the relatively low metamorphic grade, low strain and well-preserved early structures in volcanic and volcaniclastic rocks, the Orijärvi triangle (in the center of the larger Orijärvi area) is one of the few locations in the Svecofennian orogen

The Luusika potential field anomaly, eastern Estonia: modelling results [PDF]
Estonian Journal of Earth Sciences, 2018 This study considers the anomalous gravity and magnetic fields in the Alutaguse petrological–structural domain, eastern Estonia. A 10 km wide local maximum (+6.26 mGal) Bouguer anomaly field was discovered at 58.96°N, 26.61°E from the ground gravity data

Development of an in-situ magmatic dome (Svecofennian accretionnary orogen, Finland)
, 2014 This study focuses on the formation of the 100 km wide Vaasa magmatic dome (Svecofennian orogen, Finland). It is cored by diatexite migmatites and granitoids and gradually mantled by metatexite migmatites and mica schist.
