Abstract
The paper presents the results of petro and geochemical studies of the kimberlite pipes within the KhompuMay field (Central Yakutia). Their trace element data were compared with the analogues from the Yakut Kimberlite Province, Russia and the Kimberly Kimberlite Province, RSA. We present the data on petrographic composition and results of postmagmatic carbonation of the Manchary, A.P. Smelov, and Daban pipes kimberlites. The generalized model of the upper parts of the pipes show three conventional horizons: the lower horizon of least altered rocks, the middle horizon of fragments of kimberlite carbonates, and the upper horizon of intensely carbonated rocks without recognizable tex tural and structural characteristics. The obtained data on chemical and trace element compositions of rocks from pipes of the KhompuMay field reflect their material specificity, suggesting similar conditions for formation of kimberlites in Central Yakutia and South Africa.
