Kichikalaiskii West


Occurrence number: 
Longitude: 72.42, Latitude: 39.85

Conglomerates and schists are the country rocks of the West Kichikalaiskii intrusion, the first igneous phase of which is represented by aegirine-augite syenites. Close to the margin of the intrusion they grade into garnet-bearing, melanocratic, fine-grained syenites and shonkinites. Feldspathoidal syenites comprise the last intrusive phase and these have been affected by processes of albitization and liebeneritization. The intrusion is encircled by a 200 m wide zone of hornblendites.
