| Caption: | Dolomite. Quarry on Nottylees Farm, 600 yards south-east of Carham station. Roxburgh. |
| Description: | A brownish-cream, fine-grained, compact, structureless dolomite. Composed of granular, occasionally rhomboid dolomite, grain-size 0.03 mm. There is a considerable quantity of opaque white material which usually occurs as clusters averaging 0.01 mm across, embedded centrally in the dolomite grains. As this structure seems unlikely to be original, it suggests that the dolomite, in spite of its small grain, is recrystallized. Argillaceous matter may be present as coatings on the dolomite grains. In places stylolitic films separate the rock into small irregular nodules. Dolomite, micrograined, uniform granular, taxichnic. SL0220. Britrocks S35074. Magnification x40. Light PPL. |
