MINERAL MICROINCLUSIONS IN CUBIC DIAMONDS FROM THE YAKUTIAN DEPOSITS BASED ON ANALYTICAL ELECTRON MICROSCOPY DATA

Abstract

In the course of this study, we examined whitish gray crystals from the Yubileinaya kimberlite pipe (samples 1 and 2), gray and greenish yellow crystals from the Aikhal pipe (samples 3 and 4), black crystals from the Udachnaya pipe (sample 5), and orange-brown and brown-gray crystals from the Anabar placer (samples 5 and 6). All crystals were virtually opaque owing to the presence of numerous microinclusions and defects.
