Geological information for mineral exploration

SGU Map viewer

A very important part of SGU's work is to map and document Sweden's geology. Our information on bedrock, rock quality, soil types, geochemistry and geophysics provides comprehensive information for anyone working with exploration for ores and industrial minerals.

Map viewer Bedrock 1:1 million

Section of a map from the map viewer Berggrund. Illustration.

The map viewer "Bedrock 1:1 million" gives an overview of Sweden's bedrock. The information can be used as a basis for very general planning, analysis, research and education. The map image is adapted for presentation at a scale of 1:1 million, which means that the information is generalized and not intended for more detailed use.

Geological data

Here you will find SGU's geological data in various subject areas. The information can be used in your own GIS programs, for example for analyses, searches and combinations with other data. We offer data in several ways, for download in different formats or via API and Web Map Services (WMS).
