Figure 13: Pinda Group. A-D) Tight dolograinstone, partly dolomitized. Only the outer parts of calcareous grains are replaced by cloudy dolomite, the cores are not. It is not clear whether the rather hyaline dolomite between the allochems resulted from replacement only or it includes some cement. C-E) Some "intercrystalline porosity" can be detected. F) Red arrows point to limited leaching porosity within undolomitized grain cores. A, C-F) TL transmitted light; B) PL polarized light (analyzed). For confidentiality purposes the sample depths and the name of wells are not provided.
