The Chagvedaiv intrusion is situated in Archaean biotite gneisses and takes the form of a stock with an area of 1 km2. Eliseev (1958a) considers it to be a multiple intrusion in which albite syenites were emplaced as the first phase, followed by quartz nordmarkites then granosyenites with the last phases pegmatites and quartz veins. Aegirine and riebeckite are present in some rocks.
