Location: 
Longitude: 80.7, Latitude: 49.05

Situated in the Keregetas Mountains the intrusion lies within extrusive deposits of Carboniferous age and upper Palaeozoic granitoids. It is somewhat elongate and dyke-like in form the length being 9 km but the width varying from only 100 to 850 m. It consists of biotite, riebeckite, aegirine-riebeckite and astrophyllite-riebeckite granites. In the central part of the intrusion in astrophyllite-riebeckite granites there is a zircon mineralization (Ziryanov, 1969).
