PICROILMENITE FROM KIMBERLITES OF THE DALDYN FIELD, YAKUTIA

Abstract

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.
