Abstract
The ephemeral sulphate boothite, ideally CuSO4.7H20, has been collected from a tailings dump at the Lloyd copper mine at Burraga, New South Wales. Analysis of divalent metals by atomic absorption spectroscopy gave a formula of (Cu0.860Mg0.072Zn0.055Mn0.0l0Co0.003)∑1.000S04·7H20. A trace of Fe was also present. Powder X-ray diffraction data for boothite are reported for the first time. Refined unit cell constants are a = 14.190(10), b = 6.537(2), c = 10.825(6) Å, a = 106.02(5)° (monoclinic, spacegroup P21/c). The mineral dehydrates spontaneously to chalcanthite, ideally CuS04.5H20, over several days.
