Fig. 6

Bioturbated wackestones showing different stages of dolomitization. Porosity increases with grade of dolomitization. Note bioturbation and burrows (black arrows) that are progressively substituted by sucrose dolomite rhombs. Location of the right sample is only 30 cm deeper than the middle one, but shows complete dolomitization with abundant intercrystal porosity and moldic porosity (red arrows). Left: DGF-FB, 246 mTVD, middle: MSC-4, 1138.9 mTVD, right: MSC-4 1139.2, mTVD
