| Description: | Pale bluish-grey, crystalline limestone. This specimen is Dalradian Supergroup (Precambrian) in age. BGS sample number SL137. British Geological Survey Petrology Collection sample number S 34623. Photomicrograph details: Light: XPL, Magnification: x2.5. The thin section shows interlocking grains of twinned calcite (0.5-2.0 mm) with a small quantity of iron-stained chloritic material, and grains of quartz and albite scattered sparsely through the rock. Black granules, possibly of iron ore, are disseminated uniformly, but in small quantity. In summary the rock is a medium to coarse-grained limestone with a granoblastic texture. |
