Figure 22. Chalky porosity in platform wackestone, Maries, Zakynthos.
Upper Cretaceous chalky rudist limestone, Maries-Alykes road. Packed rudist biopelmicrite. Large, virtually intact , extensively bored, rudists and rudist fragments set in a granular bioclastic pelletal micrite matrix.  Also some echinoid fragments.  Extensive leaching has partially dissolved rudist walls and has generated micromoldic secondary porosity in matrix. Even some earlier cements have been leached to yield odd "skeletal" fabrics. Long dimension = 3.5 mm.
