Picroilmenite in Nakyn field kimberlites (Nyurbinskaja, Botuobinskaja and Mayskaja pipes) meets very seldom. It is characterized by the high contents of the titan and magnesium, very low contents hematite components, and have nonkimberlitic chemical compositions. Picroilmenite is present only in garnetbearing rock inclusions (peridotites, pyroxenites, eclogites), or in metasomatic rocks (marides, glimmerites, and lamprophyric type protokimberlites). An originality of picroilmenite compositions - one of the most interesting mineralogical features Nakyn field kimberlites. Finds in placers Nyurbinskaja typical on chemical composition kimberlitic picroilmenite of the megacryste associations (not met in this kimberlitic pipe), can specify receipt of these minerals in a placers from some unknown kimberlitic pipes.
