| Description: | Silicified shale from the Charlestown Main Limestone from the Bogie Mains Quarry one mile north-west of Kirkcaldy station. BGS Sample SL 277. British Geological Survey Petrology Collection sample number MC 7649. The rock occurs in the top one feet six inches of the Charlestown Main Limestone. It is a dark grey rock with white angular specks, showing a faint undulating lamination. The rock appears to be a silicified shale, originally calcareous and rich in fossil debris. The large amount of chlorite suggests that pyroclastic material formed part of the original sediment. The silica available for silicification may also have been of volcanic origin. The rock is Carboniferous, Lower Limestone Group age. An analysis of the rock indicates only 10.75 per cent CaO compared with the main limestone 60.5 calcium carbonate. |
