GRD0014S0 | Impure Marble | Fine-grained brown marble. Nice relict laminae. Micrite protolith? Original description: Limestone. Horizontal recrystallized laminae. | California | 1 | Ritter 154, 14 J |
GRD01Y4S0 | Impure Marble | Coarse-grained calcite with small metallic oxide crystals; some oxides have a rust halo while others do not. Perhaps the latter is molybdenite?. See also M-59 and M-211 | 0 | Ritter 154, 14 J | |
GRD01Y5S0 | Impure Marble | Coarse-grained calcite with small metallic oxide crystals. Some oxides have a rust halo while others do not. Perhaps the latter is molybdenite?. See also M-58 and M-211. Original description: calcitic marble. | New York | 0 | Ritter 154, 14 J |
GRD01YDS0 | Impure Marble | Large slabby, fine-grained, foliated sample. Perhaps some relict bedding (low-grade metamorphism). Possibly from an impure limestone (marl?). Mylonite?. Original label: Penn Limestone. | California | 0 | Ritter 154, 14 J |
GRD01YMS0 | Impure Marble | Small sample of a coarse-grained marble. Nice cleavage faces on calcite and muscovite. Books of muscovite and small metallic flecks (trace). See also M-58 and M-59. | 0 | Ritter 154, 14 J | |
GRD01YNS0 | Impure Marble | Calcite-phlogopite-muscovite-plagioclase-quartz marble. Generally coarse-grained. Poorly foliated with granoblastic texture. | Alpine | 5 | Ritter 154, 3 H |
GRD01YOS0 | Impure Marble | Fine-grained grey and white marble. Relict bedding or structure? Large, euhedral oxidized pyrite porphyroblasts. Original description: dolomite marble, contains sulfides. | 0 | Ritter 154, 14 J | |
GRD01ZZS0 | Impure Marble | Marble with relict bedding. The light beds are composed of carbonate. The dark beds are carbonaceous carbonate. Some Fe-staining along fractures. Original description: carbonaceous marble. | California | 0 | Ritter 154, 14 J |
GRD02O0S0 | Impure Marble | Small sample of marble. Portions of marble are white, brown, and green. Original label: Marble. Schist pendant. | California | 0 | Camp Elliott |
