| GRD01P6S0 | Replacement Features | Small samples. Billet. TS with W86-21B. Original description: 5 pieces of rock; Possible Raibl outcrop along trail leading west from Guana. Dolomite and greenish rauhwacke-like rocks. Attitude: 295, 20 SW. | Switzerland | 1 | Camp Elliott |
| GRD01PBS0 | Diagenetic Features | Small sample. Original description: Calcite from vertical calcite-lined dike with internal sediment, deposited after calcite terminations. | Italy | 1 | Camp Elliott |
| GRD01PCS0 | Cements | Small sample and billet. Fresh break in hand sample. Original description: Platform limestone from under sill. | Italy | 0 | Ritter 154, 23 K |
| GRD01PFS0 | Replacement Features | Small, slabby sample with billet. Original description: From approximately 30 cm under Mn and is typical of brecciated platform (?) limestone. | Italy | 1 | Camp Elliott |
| GRD01PHS0 | Cements | Decent sized hand sample, it does NOT show features inn the original description. Billet. Original description: From the base of sill, showing calcite veins between platform limestone (not certain that greenish layer is platform) Note calcite grows from both ceiling and floor, therefore postdates red limestone of sill. | Italy | 1 | Ritter 154, 23 K |
