Abstract

The rare supergene mineral philipsbornite has been identified at Wheal Unity, Gwennap, Cornwall. It occurs in drusy crusts composed of minute trigonal crystals. Empirical formulae determined for two typical grains are in good agreement with theoretical expectations for members of the crandallite group. Iron, sulphate, phosphate and fluoride are the major chemical substitutions.
