Bedrock maps of Finland to new age

During the last ten years GTK has renewed the bedrock map production so that in addition to lithological maps presenting rock types and associations, also maps based on stratigraphic units are produced. As the result, we have for the first time a geological unit register that is based on international standards (ICS Stratigraphic Guide and IUGS CGI GeoSciML) and covers the entire Finland.

A map dataset at the scale 1:1,000,000 was produced by generalisation of the digital, unit-based spatial dataset that covers the whole of Finland. From this dataset, the printed map “Geological Map of Finland – Bedrock 1:1,000,000” was produced at the end of year 2016 for scientific purposes, and another one (Generalised bedrock 1:1,000,000) which is suitable for example for use at schools. A metamorphic map dataset at the scale 1:1,000,000, covering the whole of Finland, was produced as well.

In June 2017 GTK published three articles that explain the outcomes of the new approach (Special Paper 60). The first one of them is an explanation of the principles of division of the bedrock into stratigraphic units, and major units are presented. The second one is an explanation to the legend of the map “Geological Map of Finland – Bedrock 1:1,000,000”. In this article the evolution of the bedrock during 3000 million years is explained using tectonic model figures. In the third article, an explanation to the digital map “Metamorphic Map of Finland 1:1,000,000” is given, with numerous examples of variously metamorphosed rocks.

Kokkola Material Week: Towards the circular economy

The GTK, together with other research, education and development organizations in the Kokkola region, organizes an annual Kokkola Material Week (www.materialweek. fi) event. Finland’s leading experts and business executives present the most recent research and development outlook for the chemical industry, the bioeconomy and the mineral economy. During the week, GTK specialists present the latest results in peat and acid sulphate soil research, as well as the mineral economy and recycling. This year’s specialty is the international battery conference, the 3rd Nordic Battery Conference (

Central Ostrobothnia has excellent opportunities for renewing the various industries. Kokkola Industrial Park is the most significant concentration of the chemical industry in Northern Europe. Together with strong chemical expertise and primary production these allow e.g. for the development of biomass value chains or utilization of lithium resources to battery chemicals.

Significant chromium resources remain undiscovered in Finland’s bedrock

GTK has evaluated chromium resources in stratiform and podiform chromium deposit types in the Finnish bedrock to a depth of one kilometre.

Altogether, 18 areas that could contain undiscovered chromium deposits were delineated in Finland. The areas are expected to contain approximately 32 undiscovered deposits.

At 50% level of probability, the undiscovered chromium deposits in Finland contain at least 350 million tons of chromium. Comparison to the known resources indicates that over 90% of the chromium endowment in Finland occurs in poorly explored or yet undiscovered deposits.
