Caption | Title Register of the original deposit: Carbonate diagenesis: Dolomitization. (A) Idiotopic mosaic of euhedral dolomite rhombs. After dolomitization, there was patchy poikilotopic anhydrite precipitation (white crytals) and then oil entered the rock. Smackover Formation, subsurface Arkansas. (B) Xenotopic mosaic of anhedral dolomite crystals. (C) Dolomitized nummulitic packstone with fine xenotopic mosaic and nummulite molds now filled with poikotopic gypsum. (D) Detail of (C) showing cloudy rhombs and clear outer zone, slightly etched, within nummulite mold. Eocene, Tunisia. |
