Lito-project
Project Leader: Trond Slagstad
To this day, 2200 of c. 3800 planned locations have been sampled .Of these, 1616 samples have been analysed.
How does bedrock composition affect the quality of groundwater? How much heat do the rocks in the Oslo-area generate? What's the natural variation in arsenic and cadmium concentrations, and how much does human emissions of these environmental poisons contribute? NGU's LITO-project can provide answers to these and other questions.
In 1999, after 33 years of work, NGU completed production of the 1:250,000 scale map series of Norway. The altogether 43 maps yield information about rock types, their distribution and relationships, and provide important knowledge about the country's geology—both as a means for research and area planning.
The maps do, however, provide little information about the rocks' composition, despite the significance of such knowledge in basic research, in environmental issues, exploitation of natural resources like groundwater and geothermal energy and area planning. In 1999, with these issues in mind, NGU initiated a nation-wide project, the LITO-project (lito=rock), with the purpose of determining the geochemical and petrophysical properties of Norwegian bedrock based on the 1:250,000-scale map series.
At least 3800 samples will be collected from all over the country. All data will be made available to the public.
