In the batholite rocks (gabbro-grandodiorites -leucocratic granites) there is no correlation between U, Th, and TR. In the differentiation process uranium accumulates in the final products (from 1.3 gamma /g to 8.5 gamma /g), thorium somewhat increases from the I phase (13 gamma /g) to the II and further remains on the same level (30 gamma /g). The behavior of SIGMA Ce- and SIGMA Y-earths in the process of rock differentiation is directly opposite: SIGMA Ce in general decreases from rocks of the I phase to vein ailites and SIGMA Y increases in the same direction; the content of SIGMA TR ( SIGMA Ce + SIGMA Y) is constant in all rocks and is approximates 400 gamma /g.
