GEOCHEMICAL ATLAS OF SWEDEN
The bedrock of Sweden has a long geological history and the oldest rocks formed 3,2 billion years ago. The Quaternary deposits covering the bedrock mostly consist of till and are younger, mainly formed c. 10 000 years ago during the latest glaciation. About 75% of Sweden’s land surface is covered by glacial till, the material on which this atlas is based. Through chemical analyses of the till we now have a better understanding of how the elements vary in the till in different parts of the country. These variations affect e.g. water quality and the health of humans and animals. Knowledge of the natural distribution of elements is of great value in mineral exploration but also in infrastructure planning and health and environmental work. We hope that this atlas will have a wide range of applications.
