Indications of participation of deep-seated sources in genesis of Seligdar-type apatite ores

New data on isotopism of carbon and strontium in calcites and apatites of the Ust'-Chul'man knot and Pb-Pb-dating of apatites in the knot manifestation are given. For the first time among Seligdar-type deposits an object is detected, where calcites and apatites of carbonatites as regards strontium isotopism are similar to the same parameter of the Arbarastakh massive, which is genotypical of the Aldan shield. The conclusion is made on the formation of ore carbonates from the substance of deep-seated sources. The fact of the delay in time of meneralization of the late stage in the ore knots of the Nimnyrsk structural-metallogenic zone in the direction from south to north is ascertaine
