PETROLOGY AND GEOCHEMISTRY OF SUBVOLCANIC BODIES OF KUMIRSKOYE DEPOSIT, GORNY ALTAI
Subvolcanic bodies formed antidromically from granites to dolerites in Kumirskoye scandium- uraniumrear-earth deposit have been described for the fi rst time. Granite-porphyry and alaskite-porphyry formed earlier build up Kumir stock, in contact with which complex metasomatites originated, from feldspathoids to propylites. Granitoids were formed controlling by partial melting of mantle substance (quartziferous eclogites) and relate to A-type (anorogenic granitoids), and dolerite dykes formation is characterized by mantle-crust interaction: amalgamation of mantle basaltic magma and crust material.
Key words: petrology, geochemistry, granite-porphyry, alaskite, anorogenic granitoids, dolerites, antidromic succession, mantle-core interaction.
