New Geochemical Criterion of Rare Metal Mineralization in the Giant Lovozero Pluton (Kola Peninsula)

摘要

Elaboration of geochemical criteria of ore potential in natural magmas is among the most essential issues in modern geochemistry. Prospecting, exploration, and estimation of magmatic ore reserves are closely related to elucidation of the genesis of deposits. Investigation of the probability and mechanism of ore mineral accu- mulation during the formation of ore-bearing bodies and horizons is also important for solving the problem formulated above. The present communication is devoted to elucidation of favorable conditions for the formation of cumulative deposits and elaboration of criteria of ore potential in alkaline magmas, because their differentiation produces the largest deposits of phosphorus, rare earth elements, zirconium, niobium, and other elements.
