No. Abbreviation/ Unit name: Description
110 Mo/ Moraine: Moraine
210 Sy/ Syenite: Syenite
220 Gr/ Granite: Granite and pegmatite
230 Di/ Diorite: Diorite and quartz diorite, partly tonalitic in north Mefjell.
250 Mgm/ Migmatite: Migmatite in Balchenfjella
Northeastern Terrane
310 Gnbh/ Biotite-hornblende gneiss: Biotite-hornblende gneiss and hornblende gneiss containing garnet in places. Thin layers of sillimanite-garnet-biotite gneiss, amphibolite and pyroxene-granulite are intercalated.
330 Gnb/ Garnet-biotite gneiss: Garnet-biotite gneiss intercalating thin layers of orthopyroxene-cordierite-garnet gneiss
350 Ch/ Charnockite: Orthopyroxene quartz feldspathic gneiss (charnockite and enderbite), generally containing hornblende and biotite with or without garnet or clinopyroxene.
Southwestern Terrane
410 Gnbh/ Biotite-hornblende gneiss: Hornblende gneiss and hornblende gneiss, containing garnet in places. Thin layers of garnet-biotite gneiss and amphibolite are intercalated.
420 Gnb/ Biotite gneiss: Biotite gneiss, containing garnet and staurolite in places.
440 Sch/ Amphibole schist: Amphibole schist, containing epidote and chlorite in places.
460 To/ Metatonalite: Metatonalite associated with amphibole schist.
Small geologic units such as monzonite, gabbro, marble and amphibolite are not shown because of their small distributions.
