Abstract

Caryinite from Låmgban, Sweden, and arseniopleite from both the Långban and Sjö Mines in Sweden, are re-examined chemically and crystallographically. Both species are monoclinic, with space group C2/c, and similar lattice parameters. The general formula for caryinite is Na4Ca4Ca4(Mn,Mg)8(AsO4)12, and that for arseniopleite is Na4Ca4Mn4(Mn,Mg)8(AsO4)12. The species status of arseniopleite remains uncertain; it may have Mn dominant in the M(1) site.
