GRD00RNT0: Slide 1: Half of the slide is composed of the finer-grained material, and the other half is composed of the sandy material. Fine grained: Carbonate with trace opaques. Sandy material: Larger wispy lenses of brown sand. Occasional rounded sparrite in some lenses (echinoderm fragments?). Occasional opaques. Styolites? (C. Eichler)
GRD00RNT1: Slide 2: Polished thin around the edges. Mainly composed of the sandy material. Sandy material: Larger wispy lenses of brown sand, some containing rounded calcite rhombs. Occasional rounded sparrite in some lenses (echinoderm fragments?). Occasional opaques. Styolites? (C. Eichler)
