Weichselian glacial stratigraphy in Hyvinkaa, southern Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1999
Two tills in Hyvinkää represent one Weichselian glaciation: the lower till, named the Tanssikallio Till, being a basal lodgement till formed during the initial stage of the last Weichselian glaciation, and the upper till, named the Hyvinkää Till, being a

Porosity of the fine fractions of Finnish tills [PDF]

open access: yesBulletin of the Geological Society of Finland, 1984
Pore properties of 64 soil samples were studied with mercury porosimetry. The samples were typical Finnish tills and related materials. All samples show porosimetry curves with strong mercury penetration around the pore diameters of 6 μm.

Ice-marginal ridge relief complex in northern Kola Peninsula (NW Russia): morphology, structure, and genetic interpretation [PDF]

open access: yesBulletin of the Geological Society of Finland
A widely spread ridge relief complex was formed by the last ice cover in the northeastern part of the Kola Peninsula. The complex belongs to the ice-marginal formations of the ice streams of the north-eastern Fennoscandian Ice Sheet.

The relation between unit weight and geochemical and mineralogical compositions in the fine fraction of till [PDF]

open access: yesBulletin of the Geological Society of Finland, 1992
A routine method for measuring the unit weight (UW) of the fine fraction of till was developed. The material was crammed into a 1.5 ml glass tube with a laboratory shaker for 75 sec. The upper half of the material was then poured away, and the volume and

Composition and origin of the Middle Weichselian interstadial deposit in Veskoniemi, northern Finland [PDF]

open access: yesEstonian Journal of Earth Sciences, 2010
The stratigraphy and sedimentology of a diamicton-stratified sand deposit have been studied in the Veskoniemi area, near Lake Inarijärvi in central Finnish Lapland. Test pit excavations were used for stratigraphical investigations.

Radar stratigraphy of the glaciotectonically deformed deposits in the Isoniemi area, Haukipudas, Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 2009
The study of deposits in the central areas of Weichselian Scandinavian Ice Sheet (SIS) is important for understanding behaviour of the ice sheet. This study provides new information on the deposits in the previously poorly known glaciofluvial Isoniemi ...

Acidification of till in Northern Finland: experimental study [PDF]

open access: yesBulletin of the Geological Society of Finland, 1996
The acid neutralizing capacity of till and some effects promoted by increasing acidity, were studied in a number of tills in northern Finland. pH profiles were measured in the field and acid neutralizing capacity (ANC mmol/100 g sample) in the laboratory

Two-dimensional apparent microfabric of the basal Late Weichselian till and associated shear zone: case study from western Latvia [PDF]

open access: yesEstonian Journal of Earth Sciences, 2008
The examination of glacial sediments in thin sections has become a common procedure in recent years. Apparent sand grain orientation (microfabric) in thin sections is one of the key elements marking certain microstructures.

Glacial geology and till geochemistry in ore exploration in the Tervola area, southern Finnish Lapland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1998
Glacial geology and till geochemistry were studied in an ore exploration project in the Palaeoproterozoic Peräpohja Schist Belt in the Tervola area of southern Finnish Lapland. The starting point for the exploration were numerous Au-Cu-rich erratics, the
