Senegalite

General
Category| Mineral
Formula
(repeating unit)| Al2(PO4)(OH)3⋅3H2[1]
Identification
Color| Colorless, Light yellow[2]
This rare specimen of a rediscovery features large boxwork-like cavities lined with senegalite and various phosphates species in a limonite gossan matrix.

Senegalite is a rare aluminum phosphate. It is a hydrated hydroxy phosphate of aluminum. It is named after Senegal, the country in which it was first found to occur.[4][5]

The molecular structure of the phosphate mineral senegalite is Al2(PO4)(OH)3⋅3H2O.[6][5]
