A 300 m sequence banded metasilt and metasandstone is exposed along the flanks of Mt. Nakkefjell. This sequence is the highest sedimentary unit of the Balsfjord group of the Lyngen Nappe Complex in the Ullsfjord area.
The metasiltstone is here seen as rhytmically layers (1-10cm). Porphyroblast of staurolite and garnets occurs in some of these layers.

Mineralization age: Wenlock : 432 ± 2 Ma

Important note: This table is based only on rock and mineral ages recorded below 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.
