Native Cobalt from the Regolith of Mare Crisium

Abstract

For the first time, high-purity native cobalt was detected in two preparations from a lunar regolith sample delivered by the Luna 24 automatic station. Presumably, it was formed during the condensation of a substance from an impact gas-plasma cloud. Previously, native cobalt of similar purity was observed only in products of low-temperature hydrothermal alteration of hyperbasites.
