These microfacies have been studied on the basis of orthochem and allochem elements, their percentages, and their texture in the stratigraphy section .

In classifying limestone, various attempts have been made, notable among them are the classification scheme of Folk (1959,1962) which was based on three components: allochems
, matrix and cements.
Ooids account for 78 percent of allochems
in mud-free samples of the lithofacies and 66 percent of allochems
in the lithofacies overall.
