Abstract
Based on the obtained evidence of hot heterogeneous accretion of the Earth and the calculated quantitative model of kimberlite magmas, the nature of the main features of kimberlites is explained. Their presence only within ancient cratons is conditioned by the crystallization of the magma ocean. The formation of kimberlites from residual melts in the bottom peridotite layer resulted in the enrichment of kimberlites with melt-like components, the presence of diamonds in them, the small volume of bodies and the scattered distribution. Decompression solidification of magmas at the shallow stage of ascent is the cause of the explosion under the influence of the preserved pressure of the gas phase and the absence of kimberlite lavas.
