Pelmicrite
stones are generaly micrite, locally pelmicrite, sparite and pelsparite. At the bottom there is a dolomitic level and at the top there is a breccic level which are both 15-20 m. in thickness. However the paleontologic studies are pointed outFour different facies have been recognized; pelmicrite, mudstone–micritic limestone, biomicrite–bio-oomicrite and biosparite–oosparite. They reflect deposition on a carbonate ramp.

Two classification systems have been widely used in the industry: Folk (1959,1962) Classification. Dunham (1962) Classification. Both classifications provide an indication of depositional energy setting and reservoir quality.
