Abstract
Cacoxenite1 is a widespread highly hydrated basic ferric oxyphosphate mineral distributed in gossans, iron-and manganese-bearing novaculites, and an occasional constituent of ferruginous soils and sediments. For long a troublesome aspect of mineralogic science and extensively investigated in the past, cacoxenite remained an enigma for lack of suitable material for X-ray diffraction single crystal study. We have now obtained a suitable specimen and report here that it has a framework structure containing enormous channels.
