A nepheline syenite pegmatite located geologically in the westernmost margin of the Igdlerfigssalik center, one of the units in the Igaliko nepheline syenite complex. Geographically it is located at an altitude of 270 m, on the Narsaarsuk Plateau, on the western foot of Igdlerfigssalik Mt. The pegmatite is found less than 1 km from the southern end of the moraine at the entrance of the Korok Fjord.

The pegmatite is especially rich in miarolitic cavities, and covers an area about 200 x 500m.
