Abstract

The article is devoted to the study of diamonds of the I and IV varieties (according to the classification of Y.L. Orlov) from Snap Lake kimberlites. Based on the study of the morphology, the impurity defects of nitrogen and the internal structure of these diamonds, it was found that the uncoated crystals and the cores of coated diamonds were formed under similar conditions. It is assumed that the coats were formed on a significant part of the formed diamonds under mantle conditions, and their etching occurred at the hypogenic stage of the development of the kimberlite body.
