Historic and unique
• roots go back to time of Swedish rule, 1500-1600 – century
• practice was started in 1730's by Daniel Tilas (1712-1772)
• in Finland great supporters were prof. Aarne Laitakari and Martti Saksela in 1930’s
• top season was in 1950-1970’s when the most ore prospecting companies had their own layman’s
sample offices and practices
• big national campaigns were in 1930’s Malminuotta, 1960’s Malmimarssi ja 1980’s Malmimania
• the oldest layman’s samples in GTK archives are from year 1924
• today only GTK is taking care of layman’s practice in Finland
• internationally wery rare, only in Sweden (SGU) and in Finland (GTK)
• GTK’s layman’s sample office is in Kuopio
Layman’s sample practice
• GTK’s layman’s sample practice provides citizens who are interested in rocks a
chance to send rock samples for analysis free of charge. Each analysed sample will
be investigated, and the research results will be delivered to the sender in a letter.
• practice include ore, industrial mineral, natural stone and precious stone samples
• create a basis for raw material resources mapping and studies
• helps to find new mineral and ore deposits
• bring benefit to the sender of the sample and the GTK and in best case new
industry and working places to the finding area
• increases in a positive way public awareness of geology and the significance of the
material resources and the geological study
• based on the everyman’s rights and the mining law

-boulders 1960 – 1980
-includes layman’s boulder and
bedrock sample data from several
ore prospecting companies
- about 9650 samples
GTK layman’s office on line
sample data:
- includes reported boulders
- includes place and analyse data
- samples beginning from year 1989
- about 7300 samples
- the data is transferred to the
GTK’s public archive after one
year waiting period
- public data service is under
development, the problem is the
confidentiality of sample senders
personal data (names, addresses
etc. according toFinnish law)
Twenty-seven of the ore mines in Finland have been discovered on the basis of a layman's sample. Currently five of these mines are still operating. I
