| Description: | Dolomite of uniform grain size, 0.5-1.0 mm. This specimen is Cambro-Ordovician in age. BGS sample number SL 176. British Geological Survey Petrology Collection sample number S 34841. Photomicrograph details: Light: PPL, Magnification: x2.5. The grains are equidimensional and anhedral, no rhomboid outlines having been observed. Limonite is present in small quantity as granules and intergranular films. Some granular quartz and ferruginous matter are also present. The image shows a breccioid structure in dolomite. Recrystallization to coarse grain has taken place along sharp-walled channels separating portions in which recrystallization to smaller grain has occurred. |
