Ultrabasic alkaline massif just southwest of the Khibiny massif.
56 valid minerals. 4 (TL) - type locality of valid minerals. 6 erroneous literature entries.
This information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This data will improve over time as more accurate maps and data sets are added.

|Archean2500 - 4000 Ma||Archean intrusive and metamorphic terranes|
Intrusive and metamorphic terranes
Belmorian Gneiss Complex
Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
