GRD01IOT0: Slide 1: Silicified micritic limestone. Slightly bedded. Skeletal material and micritic pellets interbedded with micrite containing little to no skeletal material. (C. Eichler)
GRD01IOT1: Slide 2: A majority of the thin section is composed of cryptocrystalline quartz bearing dolomite rhombs. Dolomite veins cross-cut the thin section. The top and the bottom of the thin section is composed of the same material observed in slide 1. (C. Eichler)
