▪ Sharigyn, V.V (2019): Phase CuCrS2 in iron meteorite Uakit (IIAB), Buryatia, Russia: Preliminary data. In: "Minerals: Structure, Properties, Methods of Investigation”. 9th Geoscience Conference for Young Scientists, Ekaterinburg, Russia, February 5–8, 2018. Springer Proceedings in Earth and Environmental Sciences book series. Chapter: 34.

Abstract:
Preliminary data on the occurrence and chemical composition were obtained for phase CuCrS2 found in iron meteorite Uakit (IIAB). This phase may be the potentially new mineral for meteorites. It was observed in small phosphide-sulfide inclusions in kamacite in association with daubreelite, troilite and schreibersite. Chemical composition is Cu0.94Fe0.09Cr0.97S2.00. It is suggested that in similarity with synthetic phase the Uakit mineral may be trigonal CuCrS2 (R3m or R-3m) and seems to belong structurally to the caswellsilverite group.

Il nome della specie minerale, regolarmente approvata, è grokhovskyite (IMA 2019-065) e può essere classificato come membro del gruppo della delafossite (sottogruppo caswellsilverite).
