Abstract
The article describes the petrography and mineralogy of xenoliths ilmenite-phlogopite containing deformed and granular peridotites from the Udachnaya-Eastern pipe. The age of pholopite porphyroclast from the studied deformed xenoliths matches with age of phlogopite megacryst and itself hosted kimberlites from Udachnaya pipe indicating the following processes closed in time: 1) crystallization of the low-Cr megacryst association; 2) deformation of rocks on the mantle lithosphere - asthenosphere border during the kimberlite-forming cycle; 3) formation of protokimberlite melts.
