| Caption: | Kirkby's VII Limestone. Shore at Randerston. Fife Region. |
| Description: | Buff-grey, finely saccharoidal dolomite with cavities containing tiny crystals of ankerite, refractive index omega = 1.715. In thin section the rock is seen to be completely recrystallized to a mosaic of irregular grains of carbonate, 0.1 - 0.2 mm across, which are partly turbid, partly clear. Ghosts of shells and of finely granular matrix are outlined and depicted by dust patterns and variations in grain persisting through the recrystallized carbonate, which is a ferriferous dolomite with refractive index varying slightly about 1.690. Perfect rhombs of carbonate in the fine-grained dolomite are probably ankerite similar to the crystals of the cavities. Ferriferous dolomite, fine-grained, zoophasmic. SL0031. Britrocks S34453(a). Magnification x40. Light PPL. |
