ABSTRACT
Limestones from Minia Formation (Middle Eocene) of the Nile Valley have been analysed for major elements, acid-insoluble residue (I.R.) and strontium. The Limestones, composed almost entirely of calcite, are characterised by low contents of magnesia and I.R. The amounts of SiO2, TiO2, AL2O3 and to some extent Fe2O3 are controlled by the contents of I.R. No visible correlation has been obtained between the abundance of major elements and the type of facies. Strontium is relatively abundant in the deep-sea facies compared with the shallow marine facies.
