Dalbykha-South

This includes three distinct bodies, which are situated 1.5 km south-southeast from the Dalbykha complex. They range in size from 0.1x0.2 to 0.3x1 km. The central part of the largest intrusion is composed of olivine melanephelinite, which contains 30-65% of clinopyroxene, 5-20% of olivine and minor titanomagnetite, phlogopite, apatite, titanite and perovskite. An ijolite dyke forms a ring around the intrusion which, in places, contains xenoliths of melteigite and fine-grained olivinite. The ijolites are cut by dykes of alkaline syenite.
