In the other case, this microfacies is composed mainly of ... The biomicrite which the main component of this facies is generally attributed to the deposition in pelagic environment. The absence of ammonite and only the presence of apticus shows that ammonite having aragonitic shells did not find a chance to be fossilified. This indicates that the sea floor was below the aragonite compensation depth.It represents fossiliferous biomicrite in Falk classification.

Biomicrite is light gray in hand specimen with well-preserved benthic bioclasts (Fig. 3c). Microscopically, there is lime mud between bioclasts. Dominant organisms in biomicrite are fusulinid, ostracod, and foraminifera. Due to cementation of lime mud between bioclasts, the primary intergranular pores are not developed in biomicrite (Fig. 3d).

Here we report on a systematic laboratory study of the influence of stylolites on permeability in limestone. Our data demonstrate that, contrary to conventional wisdom, the studied stylolites do not act as barriers to fluid flow. In detail, when a stylolite occurs perpendicular to the direction of flow, the permeability simply follows the same ...It contains mainly biomicrite and biosparite limestones (99% calcite LMC, < 0.5%mol MgCO3, 1% quartz), except for a thin interbedded dolomitic level (99% dolomite, 1% quartz).

In oil and gas industry, classifying carbonate rocks is a major step in core and thin section description. Two classification systems have been widely used in the industry: Folk (1959,1962) Classification. Dunham (1962) Classification.
