Abstract

Arctic Yakutia territories contain many diamondiferous placers but primary diamond sources are unknown so far; therefore, the problem of Yakutia
Arctic region is pressing. Kimberlite bodies of the northeastern Siberian platform have extremely low diamond content and they cannot be main diamond
suppliers to old and present-day placers. As part of this problem solution, zircon samples from Ebelyakh, Chimidikyan, Lena, Muna and Molodo rivers as well
as from Carnian Triassic gravel gritstones of Belkur area were studied. The U-Pb dating data obtained help to reconstruct kimberlite magmatism history,
pattern and occurrence sequence and migration paths of kimberlite material and diamonds.
