Chemical Composition of Crystalline Rock Fragments From Luna 16 and Luna 20 FinesThis paper deals with the chemical composition (bulk, rare earth, and trace elements) of the Luna 16 mare regolith and Luna 20 highland regolith, as shown by 14 basaltic rock fragments (Luna 16) and 13 rock fragments of the ANT suite (Luna 20). On the basis of bulk composition, two types of basaltic rocks have been differentiated and defined in the Luna 16 regolith: mare basalts (fundamental crystalline rocks of Mare Fecunditatis) and high-alumina basalts. The bulk analyses of rock fragments of the ANT suite also enabled distinction of two rock types: anorthositic norites and troctolites and/or spinel-troctolites (the most abundant crystalline rocks of the highland region, the landing site of Luna 20), and anorthosites. The chemical composition of Luna 16 and Luna 20 regolith samples is compared. Differences in the chemistry of the Luna 16 mare regolith and that of mare basalts are discussed. The chemical affinity between the Luna 20 highland regolith and (a) anorthositic norites and (b) troctolites and/or spinel-troctolites has been ascertained.
