Surficial geology

Quaternary research in surficial geology covers a wide range of basic and applied research topics. Basic research focuses particularly on glacial geology, Quaternary stratigraphy and glacial sedimentology, palaeoenvironmental and palaeoclimate change and microfossil (pollen and diatom) studies. Practically all the ongoing basic research projects are international and multidisciplinary linked to the global change issues in northern hemisphere and the Arctic. The research in the applied fields includes hydrogeological research, ore prospecting techniques in the glaciated terrain and sustainable use of sand, gravel and peat resources. Applied research projects are often carried out in collaboration with private companies or national research organizations such as the Geological Survey of Finland.



Paleoecology is research branch of surficial geology. It uses data from fossils preserved in peat and lake sediments to reconstruct the ecosystems of the past. Paleoecology's aim is, therefore, to build the most detailed model possible of the living environment of those organisms (such as plants, diatoms, beetles) that we find today as fossils.



History of the eastern flank of the Scandinavian Ice Sheet during the Weichselian Stage (HISIS project)
Project is funded by the Academy of Finland 2005 - 2007. Collaboration with the Geological Survey of Finland, Institute of Geology, Karelian Research Centre (RAS), Department of Geology, University of Helsinki, Nordic Laboratory of Luminescence Dating, Risø, Denmark, Godwin Institute of Quaternary Research, University of Cambridge, UK. The project is part of APEX (Arctic Paleoclimates and its Extremes) initiative. (Prof. J.P. Lunkka)


Past Climate Extremes in the North (PACE)
This research project studies past global changes. The focus is on relatively fast and important climatic and environmental transition periods in the Mid-Pliocene, in the Late Pleistocene, and up to recent times in the northern European arctic and subarctic areas. The project will establish those important boundary conditions that constrain our understanding of the Arctic and its role in global climate change. These extremes are highly relevant to predictions of our future climate in the North. Research activities are divided into three subprojects. Subproject 2 "Onset and decay of last cold stage in NW Russia" is hosted in the department and can also be seen as a contribution to the International Polar Year 20072008. (Prof. J.P. Lunkka)


The application of Ground Penetrating Radar for architectural element analysis of glaciofluvial formations
This joint venture with the Geological Survey of Finland, Kokkola office aims to develop new methods for the geological modelling of the aquifer areas. (Prof. J.P. Lunkka)


Geology and Mineralogy

Research activities in geology and mineralogy are mainly concerned with geological processes emphasized on the generation and evolution of the Finnish Paleoproterozoic bedrock.  Important applications are examining geological formations, searching and utilization of economical occurrences and environmental questions. Magmatic processes and mafic intrusive rocks, especially Paleoproterozoic, layered intrusions have been studied intensively. Alkaline rocks and carbonatites of the Fennoscandian Shield form also an important research subject. PGE, Cr and Ni-Cu ore deposits have been an essential area in the study of mineral resources. Recently also Au, Zn-Pb, and W mineralizations related with the Paleoproterozoic formations have been a target of study. Issues of tectonics, structural geology and metamorphic petrology have been concerned with many research projects. Collaboration with Finnish industry on applications of petrology and applied mineralogy forms a remarkable sector of the research.



Basic-ultrabasic magmatism and related PGE-Ni-Cu mineralization
Basic-ultrabasic magmatism and related ore mineralization has been one of the main research interest at the Department of the Geosciences, of the University of Oulu during its over 40 year history. One of the main reasons for this has been the existence of early Paleoroterozoic layered intrusions in Archean greenstone belts in Northern Finland not very far away from Oulu. The greenstone belts and layered intrusions of Finland are known to host several types of ore deposits, including chromite, vanadium bearing titanium and copper-nickel-PGE deposits.

Multi-stage evolution and fault rocks in deep sections of ductile shear zones
Svecofennian and Karelian domains in Finland are intersected by a number of shear zones that yield excellent material for this research focused on characteristics of imperfectly known deep parts of shear zones.


Petrogenesis of impact-related rocks
This study deals with generation of specific, extremely high-temperature mineral species and character of metasomatic alteration associated with certain meteorite crates.


Petrology and structural evolution of paragneisses at Olkiluoto, nuclear waste disposal site in SW Finland
The work is concerned with petrological evolution of Svecofennian, migmatitic paragneisses and their poly-phase deformation history.


Soapstone and sustainable use of it
This work will be carried out in collaboration with Finnish soapstone industry and GTK and it is aimed to generate international recommendation for naming and classification (IUGS) of different soapstone types. Another of the main topics is the determination of essential physico-chemical and technical properties and their textural and mineralogical controls.
