GRD00ZJT0: Slide 1: Fine-grained carbonate. Portions are slightly more coarse-grained. Sugary texture. Small sparrite vein cross-cuts top of slide. (C. Eichler)
GRD00ZJT1: Slide 2: Fine-grained carbonate. Portions are slightly more coarse-grained. Sugary texture. Small sparrite vein cross-cuts top of slide. (C. Eichler)
GRD00ZJT2: Slide 3: Fine-grained carbonate. Portions are slightly more coarse-grained. Sugary texture. Small siliceous lense near side of slide. (C. Eichler)
GRD00ZJT3: Slide 4: Fine-grained carbonate. Portions are slightly more coarse-grained. Sugary texture. Small sparrite vein cross-cuts corner of slide. (C. Eichler)
GRD00ZJT4: Slide 5: Fine-grained carbonate. Portions are slightly more coarse-grained. Sugary texture. (C. Eichler)
GRD00ZJT5: Slide 6: Fine-grained carbonate. Portions are slightly more coarse-grained. Sugary texture. (C. Eichler)
GRD00ZJT6: Slide 7: Fine-grained carbonate. Portions are slightly more coarse-grained. Sugary texture. (C. Eichler)
GRD00ZJT7: Slide 8: Very different from the other slides. 70% oolites and pellets, 15% quartz crystals, 10% sparite cement, 5% skeletal material. Quartz crystals are overgrowths on original rounded quartz grains and have replaced the bordering calcite (oolites truncated). Spaces between oolites are filled by optically continuous sparite (each void - a single crystal). 5 mm long crinoid material. (J. Gee)
