| Description: | Dull greyish-white, compact dolomite banded with less fine-grained, gritty cream-coloured calcareous dolomite. In thin section the compact dolomite is composed of a close aggregate of rhomboid granules, about 0.005 mm across, of dolomite among which calcite is abundant, and through which angular grains of quartz, up to 0.2 mm in size, shreds of colourless mica and fragments of pelitomorphic dolomite are irregularly distributed. The gritty portion is composed of angular grains of quartz, up to 0.5 mm, and numerous pseudo-ooliths of pelitomorphic dolomite which with subordinate microcline and fine-grained silica-rock are cemented by rhomboid dolomite of varying grain and by shapeless calcite. Dolomite, arenaceous and dolomitic sandstone, interbanded, taxichnic. SL0157. Britrocks S34857. Magnification x40. Light PPL. |
