Ånnerud (Ånnerød), Våler kommune, Østfold (Smålenene) fylke, Norge
Numerous granite pegmatite dikes up to 5 m in width are criss-crossing the small Ånnerød peninsula near the old Ånnerød farm close to the lake Vansjø. When W.C. Brøgger visited the area in 1879 he found more than 50 small feldspar (and also quartz) quarries and prospects in the area.
One pegmatite dike, Lauritzgangen, could in 1879 be followed for about 200m, another dike, Store-Anderstaget, could be followed for about 250 m.
