These aluminium phosphates have been described in some detail by Du Toit (1917) and Hutchinson (1950).

These aluminium phosphates have been described in some detail by Du Toit (1917) and Hutchinson (1950). The aluminium phosphate distribution map (Fig. 25) shows how outcrops of the phosphate rock occur sporadically about granite hills north and south of Saldanha Bay. They are not confined to any particular altitude. The degree of phosphatization is very variable over the area and even varies within any particular hand specimen. On Konstabelkop the phosphate rock is hard and of 3 3°..
