The dolomite crystals show subtidal to intertidal zone of deposition with frequent episodes of flooding (Kobayashi, 1999).The diagenetic products of microfacies such as Ferron dolomite and spary calcite cementation indicates replacement during the burial diagenesis.
Whiffin was first proposed to apply microbial diagenesis to cement the loose sand particles and achieved good effect in 2004 [6].
Thus, we consider that the diagenesis in general sense, e.g., a decrease in histological preservation, increased with an increase in bone porosity and mineral crystallinity.
The sedimentology and diagenesis of the Sherwood sandstones have been widely studied: Burley [52] addressed the composition of the sandstone reservoir which contains several Sr-bearing minerals, including plagioclase feldspars, as well as igneous and metamorphic rock fragments.
9) diagrams exhibit that the investigated samples, in general, have clustered in the immature (diagenesis) zone and marginally fall in the beginning of the oil zone.
The thinnest laths are 1 [micro]m; thicker laths were possibly formed by fusion in the course of diagenesis. Very narrow (about 3 [micro]m) laminae (or very wide laths?) were found in the umbonal region of specimen 4921/661 but they show excellent cross-bladed mosaic (Fig.
