MINERAL DEPOSITS AND MAGMATIC RAPKIVIGRANITE ASSOCIATIONS

The paper presents data that provide grounds for the assertion that in the process of the formation of complex anorthosite-rapakivigranite plutons, the formation of complex ore apatite-Fe-Ti and Cu-Ni-Co deposits, which are associated with the formation of basite phases and complex deposits of Li, Be, Zn, Pb, HFSE, sometimes with polymetals - with the formation of rapakivigranite associations. Reasons are given for the assertion that in the final phases of the melts that formed the anorthosite-rapakivigranite plutons, the accumulation and fractionation of HFSE, in particular, U and Th, took place. The variability of H₂O, O₂ and F fugitives could influence the processes of fractionation of chemical elements in post-magmatic fluids and, accordingly, the character of ore mineralization. These plutons control the placer deposits that formed from the decomposed matter of these magmatites.
