Abstract

During studying samples of lunar regolith from samples of the AS “Luna-24” using the methods of Raman spectroscopy, the presence of three structural modifications of carbon was established: amorphous sp2 carbon, shungite-like carbon and turbostratic graphite. At the same time, no signs of hydrocarbons or other organic compounds were found, what excludes contamination of the sample at the preparation stage and the effect of the adhesive layer of the scotch on which the regolith fragments under study were mounted, and also contamination of the sample by the exhaust of hydrazine landing engines of the descent capsule of the AS “Luna-24”.
