Abstract:
Of eruptive rocks granite is predominating. More subordinate gabbro rock and at some places perdotite occur. The stratified rocks are schists, limestone and gneiss with a few sections of slaty quartz rock. In the coast district there is a belt of schistose rocks from Gildeskaal northward to Folda and Steigen. In Beiarn and Misvær there is a great area of granite, which from here continues to Saltfjord and Skjerstadfjord. North of these fjords it reappears and now continues to Folda. Here it is, in places, so strongly compressed that it has the appearance of gneiss. In the inner part of Beiarfjord there is an area of limestone and schist, which is strongly penetrated by dikes from the granite field. East of the granite there is a large field of mica-schist with great sections of limestone and marble. It enters the southern part of the map at Misvær and Saltdalen and continues over Valnesfjord and Fauskeidet northward to the inner part of Folda. In the southeastern part the Sulitjelma field is located. Here the schistose-rocks are penetrated by considerable quantities of gabbro-rock and smaller sections of granite. The main area of gabbro is found in the Sulitjelma peaks, which are located east of the map. The granite within the range of the map is pressed out in a liquid state as laccolitic masses.
