New genetic type of scandium mineralization in the iron-ore complex of the Kovdor massif
Abstract. Scandium mineralization of a new genetic type has been discovered in the baddeleyite-apatite-magnetite deposit related to the Kovdor alkaline-ultrabasic massif, Kola Peninsula, Russia. It is represented by altered dolomite carbonatites containing a new mineral, juonniite in mineralised caverns. Juonniite occurrences are confined to a linear reactivated fault, which intersects phoscorites and carbonatites. Metasomatism of phoscorites caused almost a two-fold enrichment in Sc in clinohumite-bearing units. Late hydrothermal solutions affected cataclastic clinohumite-bearing phoscorites along the fault zone and the subsequent dissolution of sulphides and Sc-bearing minerals (e.g.: forsterite, baddeleyite, pyrochlore group minerals, etc.) was accompanied by mobilisation of traces of Sc, most likely, in the form of carbonate and sulphate. Fluorapatite-bearing altered dolomite carbonatites with abundant cavities provided the necessary conditions for the precipitation of scandium in the form of a hydrous phosphate, juonniite.
