| Caption: | Dolomite. Left bank of Whittinghame Water, 0.25 mile west-north-west of Ruchlaw Mains. East Lothian. |
| Description: | A red colour-laminated rock, seen in thin section to be composed of a fine-grained aggregate of anhedral dolomite, the grains of which are 0.1 - 0.01 mm across and are dusted with and separated by red limonite. The colour lamination corresponds to a greater or less concentration of limonite. Small rhombs of dolomite of larger size occur in sporadic cavities. Chert is abundant as irregular layers and as a pervasive infiltration; it is clearly a replacement deposit and not an infilling to fractures or cavities. Dolomite, cherty, ferruginous, pelitomorphic to fine-grained, banded, taxichnic. SL0179. Britrocks S34900. Magnification x40. Light PPL. |
