Quartz-bearing pockets (up 3 m × 3 m × 4 m in size) in a hydrothermal quartz-K-feldspar-cemented breccia with an ellipsoid structure 250 m x 500 m in size. The breccia is hosted by Late Paleoproterozoic mylonitic metarhyolite of the Formofoss nappe complex (Müller et al, 2018a,b). It is a fault-related, fluid-assisted, hydraulic breccia which formed by single pulse stress released by a seismic event.
The land is owned by Lierne Skogforvaltning. Collecting is allowed for a fee of Nkr 100 per day limited by one backpack per day (status 2003). Find of new cavities has to be reported and a new fee is agreed on.
The coordinates are those of the "centre" of the breccia.

Geochronology
Mineralization age: Middle Triassic : 240.3 ± 0.4 MaImportant 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.
