LANTHANIDES AS INDICATORS OF PROCESSES INTRACHAMBER DIFFERENTIATION (AS EVIDENCED IN SOME INTRUSIONS OF THE VORONEZH CRYSTALLINE MASSIF)
The concentrations of lanthanides in rocks of the intrusive masses of reference of the final phase of magmatic activity paleoproterozoyskoy Voronezh crystalline massif. The characteristic of the laws of distribution of rare earth elements, depending on the position of the study species in the section. The technique of diagnostic processes intrachamber Syngenesicity differentiation and spatial coincidence of magmatic formations.
