| Description: | Dull cream-coloured rock which is much fractured. It is composed of a mixture of very fine-grained turbid carbonate and re-crystallized granular carbonate of grain-size varying from 0.03 - 0.3 mm. Rarely short tubules in the fine, turbid component suggest that it is partly algal in origin. In recrystallization clay material is concentrated sometimes round the periphery of relict pieces of fine-grained carbonate, sometimes interstitially between the recrystallized grains. Angular quartz and subordinate alkali-feldspar grains, up to 0.5 mm long, occur abundantly in patches; clay is present as impersistent irregular films; flakes of chlorite and grains of chert are accessory. Limestone, irregularly gritty and clayey, fine-grained, algal, clotted in part, breccioid. SL0094. Britrocks S34560(a). Magnification x40. Light XPL. |
