Clast type 2 has an allochem
suite that is almost completely dominated by strongly aligned disarticulated and abraded thin shelled bivalves (IPosidonia) and small quantities of fine micropeloids that appear light grey in PPL.
The microfacies is characterized by skeletal allochems
which are the only allochemical constituents marked by moderate diversity of organisms with allochem
to micrite ratio of 7:3.
These microfacies have been studied on the basis of orthochem and allochem
elements, their percentages, and their texture in the stratigraphy section .
particles include pelloids, some spherical single-walled calcispheres, and rare microcrinoid ossicles.
The microfacies analysis represents the allochem
types matrix textural features and fossils content.
The microfacies analysis details the allochem
matrix textural features and fossils content of the lithofacies (WF1-WF9).
and matrix ratio is3:7, according to visual estimation, the average relative abundance of various faunal and floralconstituents is Lockhartia (15%), Operculina(1%) and Milliolid up to (7%).
type, composition, texture, sedimentary structures and rock types), three microfacies and five sub microfacies are recognized (Fig.
Bioclast is the dominant allochem
type which includes; sponge spicules (3 Percent), ostracods (3 Percent), intraclasts (1 Percent) and pellet (3 Percent).
This stage is composed of limestone with abundant larger foraminifera, algae is the second dominant allochem
On the basis of detailed field and petrographic characteristics, four microfacies with distinct textures, allochem
types, fossil contents and sedimentary structures are identified and interpreted.
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.
