Figure 7 a,b. Microporous cements in Arab Formation carbonates. Porosity in thin section is filled by blue-dyed epoxy, calcite is stained pink to red, other minerals are unstained. (a) SEM image of epoxy pore cast of three microporous grains (M) that are enveloped by microporous isopachous bladed calcite cement (MC-FC). Note the presence of abundant, thin tubular pores within the isopachous cement (arrows). Microporosity developed within micritized grains is interconnected via the microporous isopachous cements (Saudi Arabia, Berri field, Arab-C). (b) Higher magnification view of epoxy pore cast shown in the previous example. Note thin, tubular micropores (arrows) developed within the isopachous bladed calcite cements (SEM image).
