The occurrence lies on a small peninsula at the northern end of Lake Halpanen and consists of a N-S-trending carbonatite dike up to 8 m wide exposed in a quarry and a couple of small pits. Geophysical evidence indicates a probable minimum length of 1.5 km (Puustinen & Karhu 1999).

Geochronology

Mineralization age: Paleoproterozoic : 1800 Ma to 1700 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.
