Caption: Cementstones, Ballagan Beds (bulk sample of 8 bands). Ballagan Burn, 530 yards north of Ballagan House. Stirling.
Description: Compact grey rock, composed of a mass of rhomboid dolomite crystals, 0.005 - 0.02 mm across, with very little turbid matter of any kind, argillaceous or calcareous. Angular grains of quartz, 0.1 - 0.5 mm across, are abundantly scattered through the rock along with scarce alkali-feldspar, secondary quartz-rock, chlorite and thin prisms of a mineral, occurring in cracks and in association with quartz, which is probably baryte. The presence of small prisms of gypsum was suspected, but not proved. Dolomite, luteous, micrograined, uniform granular. SL0192. Britrocks S34968. Magnification x40. Light XPL.
