This occurrence is located on a number of small islands in Kovdozero Lake. Melteigite and ijolite form a body extending for nearly 0.5 km across several islands, and these rocks are sometimes distinguished by the presence of orbicular structures. About 75 dykes have been located up to several kilometers to the south. Sudovikov (1946) has distinguished two groups of dykes: (1) melteigite, which is represented by fenitized porphyries and (2) syn- and post-melteigite dykes of nephelinite, monchiquite and foyaite. The country rocks are granite gneisses and amphibolites of the Belomorsk Archaean series and these have been intensively fenitized.
