Spanish:
Årvollåsen, Oslo, Noruega


A locality that was said to be «eine der interssantesten im Kristianiagebiet» (one of the most interesting in the Kristiania area") (Goldschmidt 1911).
Originally a small quarry in "grefsensyenite".
A limestone block with contactmetamorph minerals within a nordmarkite body is now protected as a natural heritage (Årvoll Naturminne), by Royal Decree of 16 November 1984 (Regulation 1984-11-16 No. 1906).
All collecting is prohibited.

An updated survey on the locality is given in Kvamsdal(2025).
