1926 Mineral. Abstr. 3 110 Quenselite, another new mineral from Långban, Sweden, occurs as small (1 mm.) pitch-black crystals with calcite and baryte in crevices of the granular haematite ore.
1958 Proc. Nat. Inst. Sci. India A. 24 95 This is probably the first reported occurrence of quenselite in manganese ores of metamorphic origin.
1971 Zeitschr. f. Kristallogr. 134 331 The significance of the quenselite structure lies in its role as a connecting link between certain of the Pb oxides and the lithiophorite-chalcophanite group.
2001 Materials Res. Bull. 36 1844 A lead-bearing phase, the mineral quenselite, PbMnO2(OH), adopts a layered structure consisting of layers of MO6 octahedra with double layers of lead cations in the interlayer space.
