SPECIFIC FEATURES OF PICROILMENITE COMPOSITION IN VARIOUS DIAMONDIFEROUS FIELDS OF THE YAKUTIAN PROVINCE

Abstract

Picroilmenite of kimberlitic rocks is among the major typomorphic minerals widely used in geological prospecting. Therefore, the elucidation of compositional differences between ilmenites from various fields of the Yakutian province is an important issue. Sobolev was among the first researchers to note the necessity of using picroilmenite in prospecting for kimberlite fields. However, the attempts of several researchers to decipher specific features of the ilmenite composition in various diamondiferous fields were unsuccessful.
