Kovdor is after the Khibiny and lovozero massif the best known Kola locality. It is most famous for perfect magnetite octahedrons in white dolomite. Also very common are tetraferriphlogopite, and the collinsite-bobierrite-kovdorskite paragense.
Kovdor is just a mining town in the west of Kola. The actual localities are formed by two open pit mines, the Zheleznyi mine, or Iron mine and the Slyuda mine, or Mica mine,

geology
Kovdor is a so called alkaline-ultrabasic intrusion. The largest part of the intrusion consists of pyroxenite and olivinite rocks. The Zheleznyi mine works a part of the intrusion with mainly carbonatites. The Slyuda mine works a different area with mainly phlogopite-diopside olivine rock. The complicated Kovdor intrusion also houses turjaite, melilite bearing rocks and fenites. Kovdor is situated in the Kandalaksha graben, an ancient rift structure that runs from Arkhangelsk to the Finnish Sökli deposit.
