Sandermosen, Maridalen, Oslomarka, Oslo, Norge

A miarolitic rich nordmarkite (alkali syenite) with microminerals close to Sandermosen railway station in Maridalen.
This entry covers two localities:
- Schetelig (1913) reported a find of some minerals from the Sandermosen Station area that W.C. Brøgger collected in 1899). This locality has not been relocated in modern times.

- A locality on the ditch edge of a forest road about 1km nortnorthheast kilometer from the Sandermosen railway station which was discovered by the late Herman Fylling (1943-2015) around 1980. The coordinates given are for this locality.

The history, description and an update of the locality is treated by Kvamsdal (2024).
