Figure 8: Pinda Group. A-F) Yellow arrows: "sutured" grain contacts; white arrows: outer zoning in dolomite crystals, i.e., dolomite overgrowths (? replacement, then cement). A, C, E) TL transmitted light; B, D, F) CL cathodoluminescence. A-D) Porous dolograinstone, with porosity resulting from the late leaching of the undolomitized core of the former calcareous grains. In B), a feldspar grain appears in blue color. E-F) Dolograinstone with leaching vugs cemented by late anhydrite. For confidentiality purposes the sample depths and the name of wells are not provided.
