Stjernøya Island is divided administratively between 2 municipalities (kommuner): Alta and Hasvik municipalities.

The island built principally of gabbroic and ultrabasic intrusions, but there are 3 younger occurrences of alkaline igneous rocks, in 2 of which carbonatites also occur.

Geochronology

Mineralization age: Paleozoic : 540 ± 39 Ma to 402 ± 8 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
