Picroilmenite from kimberlites of the Daldyn field, Yakutia

The compositional structure of kimberlite fields is among the blank spots in the geology of kimberlite volcanism. Identification of pipe clusters within a kimberlite field is based on the geographic principle only, i.e., the spaial association of kimberlite bodies. We used one of the typomorphic kimberlite minerals-picroilmenite in-order to analyze the kibmberlite field structure. The abundance of picroilmenite, its stability during the hypergene disintegration of kimberlites and the formation of diamond collectors, and other specific features define a major role or this mineral in prospecting work.
