| Description: | Compact, mottled grey-brown and cream dolomite. Composed of a base of dolomite in grains and rhombs of 0.02 to 0.1 mm size in which relic patches of very fine-grained pelleted carbonate rock are preserved. In this base irregular patches and single rhombs of coarsely crystallized dolomite about 1 mm across are numerous. Subangular grains of quartz are sporadically abundant in both the coarse and fine dolomite. Ferruginous clay films are common locally and their material has been pressed aside by the large dolomite crystals during their growth. Dolomite, calcareous, arenaceous, fine-grained, porphyrocrystallic. SL0158. Britrocks S34858. Magnification x40. Light XPL. |
