| Caption: | Limestone. Old quarry, 100 yards N. of Stobs Quarry, Limekilnedge, 9 miles south of Hawick. Roxburgh. |
| Description: | A whitish, nodular, argillaceous limestone. Composed of a mass of granular carbonate of which the grain-size is occasionally 0.03 mm but usually 0.01 mm and often less. This has a turbid appearance and there may be films of clay on the grains, but the apparent turbidity may be caused only by the small grain-size. Through this mass small angular quartz chips (0.2 mm down) are sporadically scattered. Re-crystallization to clear granular calcite (0.1 mm grain) has taken place along impersistent sinuous or irregular channels. Limestone, luteous, micrograined, uniform granular, crook-veined. SL0208. Britrocks S35073. Magnification x40. Light PPL. |
