Abstract

The infra-red spectrum and X-ray powder pattern of a chemically analysed specimen of leadhillite, a lead carbonate sulphate hydroxide mineral from Leadhills, Scotland, are shown to be different from those in the literature. The IR spectra of several specimens suggest that mutual replacement of SO4, CO3, and OH may occur in this mineral, and it is thought that this might be responsible for the observed variation in X-ray spacings.
