Abstract
The Phosphate Formation of the Campanian-Maestrichtian in the Abou-Sabouna-Mine on the eastern side of the Nile Valley near Mamied was investigated mineralogically and geochemically. The phosphorite deposits are of the bedded type, containing collophane, francolite, smaller amounts of quartz, calcite, geothite and chlorite, rarely zircon. The phosphate material contains F− (F/P2O5=0.089−0.094), as is characteristic for francolite.
