Building material resources in Norway

Extraction and land-use planning

Mineral resources in Norway

industrial minerals (e.g. limestone, quartz, olivine and nepheline syenite)

natural stone(e.g. larvikite, granite and flagstone)

raw materials for construction (sand, gravel, crushed rock and clay)

metallic ores (iron, nickel and titanium oxide)

energy minerals (coal and peat)

The mining and quarrying industry comprises companies engaged in extracting and processing minerals and rocks from bedrock or superficial deposits.

Five categories of raw materials are distinguished:
