| Caption: | Kirkby's III Limestone. Shore at Randerston. Fife Region. |
| Description: | A rudely platy, irony, shelly rock of lumachelle type. The shells are replaced by turbid coarsely granular ferriferous dolomite, and are embedded in a matrix of carbonate stained and cemented by limonite. This carbonate is in part very finely granular, in part recrystallized to a mosaic of irregular grain up to 0-1 mm across. Its ordinary refractive index mostly is 1.700 but varies upward, the highest value observed being 1.715, indicating a content of fully 20 per cent of ferrodolomite. Numerous fragments of small shells and scarce quartz and mica are scattered through the fine-grained matrix. Ferriferous dolomite. Iimonitic, micrograined, zoichnic. SL0029. Britrocks S34451(a). Magnification x40. Light PPL. |
