Native antimony and bournonite intergrowths in galena

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 2.

This study confirms a linear relationship between a cell edge and Ag-Bi(Sb) content for galena containing less than about 15 wt. 9o Ag and B(Sb).

2015-3-1  The measured lattice constants of the impurity-doped galena shown in Table 1 reveal that the lattice constant of the synthetic PbS is 0.5926 nm, which is very close to that of the natural galena (0.5928 nm) (Wasserstein, 1951). In addition, the lattice constant of the galena decreases in the presence of Ag and Zn impurities, but it increases in

A few samples of galena show recrystallised textures and have evidently been deformed, indicating late textural restructuring. No significant concentrations of antimony or silver were detected in galena; recalculated analyses indicate approximate stoichiometry (PbS to Pb 1.1 S 0.9). Silver-bearing minerals occur as intergrowths in
