Реферат:
Yakutites are coarse (up to 15 mm or larger) aggregates dispersed for more than 500 km around the Popigai
meteorite crater. They share many features of similarity with impact diamonds found inside the crater, in elemental
and phase compositions, texture, and optical properties as revealed by X-ray photoelectron spectroscopy, X-ray
diffraction, and optical spectroscopy (Raman, absorption, luminescence and microscopic) studies. The N3 vibronic
system appearing in the luminescence spectra of Popigai impact diamonds (PIDs) indicates a presence of nitrogen
impurity and a high-temperature annealing of diamonds that remained in the crater after solid-phase conversion
from graphite. Yakutites lack nitrogen-vacancy centers as signatures of annealing, which may indicate quenching
at the time of ejection. Thus, both PIDs and yakutites originated during the Popigai impact event and yakutites
were ejected to large distances
