Map of Lead in Sphalerite


This image maps the distribution of Pb in a sample of sphalerite (ZnS) from the Pine Point Mine in NWT. The bright white "fingers" in the lower left corner are galena (PbS). The map shows that the concentration of lead is variable among the growth bands in the sphalerite. Comparison with the Fe map shows that there is an inverse correlation between lead and iron concentrations. The area mapped is approximately 4.2 mm a side.
