Almunge

The informations are from H.J.Wilke´s new - and fantastic - book on Sweden.

Almunge is a village 25 km east of the swedish town of Uppsala. Remnants of a former volcano, that had intruded old granites and gneisses and formed fenites around it, in an area of 16 km² consist of several different alkaline rock types (umpektite, canadite, foiddiorites, nephelinsyenite). Due to the intrusions in archaic rocks there are several unusual minerals for alkaline localities.

I made it there in 1998 - what a dull locality. Except for some roadcuts, that are alredy heavily weathered, there are no outcrops. I have been able to find some cancrinite, nepheline, hastingsite, and siderophyllite, but it is a place without any callecting fascination: just moss and lichen covered boulders and small ridges. Furthermore I tried to find collectors in Sweden, who might have specimens from there, but alas, not even a friend from Uppsala university (some 30 km away) could help me.

Siksjöberget

Again - from Wilke´s book:

12 km from Särna in northwestern Dalarna in Sweden there is one more small intrusion, which is rather similar to Almunge, So we can deal with it here.

Two rounded mountains are all that´s left of this intrusion - Siksjöberget and Ekorraasen. There are no quarries, just loose blocks and hardly any paths at all. (Unfortunately that´s all the information I got so far).
