Summary of knowledge about Norwegian anorthosite prospecting - in relation to Greenland anorthosites
This report gives an overview of Norwegian prospecting on anorthosites, with emphasis on the calcic types dominant in the Inner Sogn-Voss area of Western Norway.

This report gives an overview of Norwegian prospecting on anorthosites, with emphasis on the calcic types dominant in the Inner Sogn-Voss area of Western Norway. The high aluminium content of these large anorthosite bodies by the Sognefjord has made them the target of potential alternative sources for the aluminium-industry. In several phases during the last 90 years major Norwegian companies have done extensive geological investigations with this aim. The Sogn anorthosites contain a plagioclase with labradorite-bytownite composition, in the dominating range of 60-78% anorthite.\rMany large Greenland anorthosites (An60-90) prove to be somewhat higher in both acid solubility and aluminium content, thus giving them a favour to the Norwegian ones.\rThe large anorthosites in Rogaland (SW Norway) have lower aluminium content and are thus not interesting as an aluminium raw material.
