“…authors (Bannister and Hey, 1933;Kingsbury and Hartley, 1956;Guillemin, 1956;Millman, 1960;and Von Rahden and Dicks, 1967), X-ray powder methods cannot differentiate satisfactorily between the different members of the descloizite-mottramite series of vanadates. In fact Bannister and Hey (1933) conducted an X-ray investigation on the descloizite series and conclude that the powder data for the descloizite-mottramite series are identical.…”

“…In fact Bannister and Hey (1933) conducted an X-ray investigation on the descloizite series and conclude that the powder data for the descloizite-mottramite series are identical. However, Kingsbury and Hartley (1956) described occurrences of vanadium minerals in the Caldbeck area of Cumberland in which they distinguished between descloizite and mottramite by X-ray powder photography and found that measurements of the two members showed close agreement down to 1.652 A, but that smaller spacings differed markedly. Of the minerals investigated by them, none gave an intermediate pattern between those of descloizite and mottramite.…”

ABSTRACT. Descloizite, cuprian descloizite, and mottramite from most of the known prospects and mines in the Otavi Mountain Land were sampled and subsequently analysed chemically and by X-ray diffraction. Unit cell parameters were refined with the aid of a computer program. It was found that, contrary to previous opinion, chemical parameters of these vanadates can be deduced from their X-ray powder data according to the equations (correlation coefficients in parenthesis):

“…Davidson and Thompson (1948) found stibnite from St. Sunday Crag in the Helvellyn region. The occurrence of stibnite, zinckenite, jamesonite, and boulangerite in Grainsgill, near Carrock mine, was described by Kingsbury and Hartley (1956), but it is not known if these minerals were from the north-south tungsten veins or from the east-west lead-zinc crosscourse. Gough (1963) found bournonite and tetrahedrite inclusions in galena from the Greenside lead vein.…”

ABSTRACT. The Driggith vein is representative of the lead-zinc mineralization in the Caldbeck Fells area, with a primary mineral assemblage consisting of quartz, baryte, calcite, chalcedony, pyrite, arsenopyrite, galena, sphalerire, bournonite, argentian tetrahedrite, and native antimony. Broadly similar assemblages are found in Pb Zn mineralization of Upper Devonian to Permian age elsewhere in the Lake District. The paragenetic sequence appears to have been early pyrite and minor arsenopyrite associated with quartz; with later baryte, calcite, sphalerite, and chalcopyrite enclosed by galena. Within the galena occur inclusions of tetrahedrite, bournonite, and native antimony. A later stage of baryte mineralization was followed by the alteration of primary sulphides to secondary minerals. Elsewhere in the Lake District, galena occurring in this association also contains inclusions of native antimony, bournonite, and other sulphosalts, and in this respect differs from galena associated with earlier veins composed dominantly of chalcopyrite, pyrite, and arsenopyrite. The inclusions make a major contribution to the high antimony values reported in trace element analyses of galena from the Lake District. The occurrence of these inclusions, which in some cases display preferred orientation within the host galena, is discussed in terms of phase relations involving PbS and AgSbS~.
