Figure 7 c,d,e,f. (c) Thin section photomicrograph of grainstone with abundant equant calcite cement (arrows). This cement fills interparticle porosity between microporous micritized grains (MG) and probable composite grain (CG) (plane-polarized light, Saudi Arabia, Berri field, Arab-C). (d) Epoxy pore cast of microporous grains (MG) that are embedded in microporous interparticle equant calcite cements (MC) (SEM image, Saudi Arabia, Berri field, Arab-C). (e) Detail of epoxy pore cast of microporous equant calcite cement shown in (d). Note the straight, platy to laminar shape of pore throats (arrows). Pore throats intersect to form larger, poorly-defined tetrahedrons (SEM image). (f) Detail of center of epoxy pore cast of microporous interparticle equant calcite cement shown in (e). Pore throats (arrows) are less than or equal to 1 micron in size in at least one direction.
