| Caption: | Cornstone. Gargunnock Burn, 0.75 mile south of Gargunnock. Stirling. |
| Description: | A flaggy medium-grey compact dolomite, composed of turbid very finely granular dolomite, of grain-size about 0.005 mm, which is recrystallized irregularly along streaks and channels to clear dolomite of 0.03 mm grain-size. Obscure vermiform structure in the finer material suggests algal activity. Scarce secondary quartz is associated with good rhombs of dolomite in small lenticular spaces. Thin flakes of mica and angular grains of quartz are sparsely distributed and there are some relics of micro-fossils. Dolomite, luteous, pelitomorphic, microzoichnic, clotted, bedded. SL0160. Britrocks S34860. Magnification x40. Light XPL. |
