Paragenetic and General Notes
Mansfieldite is the aluminium analogue of scorodite, with which it forms a series.
At Tsumeb, pale-yellow mansfieldite has been confirmed as forming the cores of green zoned crystals of aluminium-rich scorodite on a specimen in the W. (Bill) Pinch collection (Bill Pinch, personal communication to M. Southwood, February 2015).
