| Caption: | Limestone from Chapel Limestone Quarry, near Kirkcaldy, Fifeshire. |
| Description: | A coarsely crystalline banded fossiliferous and possibly brecciated limestone from Chapel Limestone Quarry, about two miles north-west of Kirkcaldy, Fifeshire. Chapel quarries lie just north of Chapel village. BGS Sample SL 10. British Geological Survey Petrology Collection sample number MC 7569. The average thickness of the limestone is 30 feet, and the general dip is north at 10 degrees. The seam has been worked, opencast for the most part, on a length of face of about 300 yards; but development in the lowest 10 to 12 feet was by mining, the overburden being too heavy to permit of further quarrying. Immediately below the seam there is a thick sill of quartz-dolerite, and a thin dolerite dyke cuts vertically through the limestone in the western part of the quarry. The stone is of moderately good quality and has been extensively worked. A recent attempt at development, however, proved unsatisfactory owing to the tendency of the limestone to fuse in the kilns. Petrological examination has shown the presence of the mineral datolite (calcium borosilicate) in some quantity, irregularly distributed through the limestone, and associated with other alteration products of a thermal metamorphic nature. The presence of boron in considerable quantities was confirmed by the chemical analyses, and may be the cause of the difficulty in the kilns. |
