The overall sedimentary nature of the Miocene sediments in Genefa, Gharra and

Homiera sections at Cairo-Suez District in northern Egypt is dominated by shallow

marine carbonate-siliciclastic rocks and included in Gharra and Geneifa formation.

different facies types have been distinguished based on textures, 525 rock color,

grain size, sorting, roundness, components, thickness, bedding style, sedimentary

features, interpretation of depositional setting and the appearance according to

lithofacies code. These facies types were grouped into 6 lithofacies associations (LFA)

ranging from peritidal (LFA 1) to shoal margin (LFA 6).

The lithofacies types are stacked into 4 cycle types. These cycle types build up

to nine 4th 531 order cycle sets, which are vertically arranged in three 3rd orders and

subsequently subdivided into fourth order cycle sets and fifth-order cycles. The age the

three cycles are interpreted to correspond to the Late Burdigalian stage (18-16.38 M.y.),

Late Burdigalian-Early Langhian stage (16.38-14.78 M.y.) and Late Langhain-Early

Serravallian stage (14.78-13.66 M.y.).
