A diopside skarn mentioned in a NGU publication (Furuhaug & Lindahl 1977).
In the collection of the Evje og Hornnes geomuseum Fennefoss are a few samples from this locality.
The exact location is not pinpointed in the publication, but is located in a steep wall, and the mineralisation is only observed in loose boulders.
The fluorescence of our "scheelite" samples is rather more yellowish than blue, indicating that these might be powellite, rather than scheelite.
Our samples originate from the Svend Pedersen collection.

A dark brown crystal was visually identified as titanite. Some of the diopside might contain chromium, suggested by the strong green colour. However, there is no analysis to confirm this.

The coordinates are given for the place where Spilderdalen is shown on the map. I would suggest to study hoydedata.no in order to rediscover this occurrence.
