| Caption: | Photomicrograph of Charlestown Main Limestone. Light: XPL. Magnification: x2.5. Chapel Limestone Quarry, about 2 miles north-west of Kirkcaldy, Fifeshire, Scotland. |
| Description: | Compact grey limestone permeated with and containing compact aggregates of greenish-yellow structureless clay and also some microcrystalline greenish-white aggregates. This specimen is Carboniferous Limestone Series in age. BGS sample number SL 212. British Geological Survey Petrology Collection sample number S 35902. Photomicrograph details: Light: XPL, Magnification: x2.5. The limestone is composed of granular calcite of 0.1 mm grain size and over, with masses of an almost opaque, finely divided clay aggregate abundant in patches. Occasional relict organic structures are present, including foraminifera, within the chambers of which the calcite is coarsely recrystallized, and spines and occasional crinoid ossicles are also obvious. Garnet is locally developed in dodecahedra and in irregular grains or aggregates up to 0.2 mm across and the microcrystalline greenish aggregate seen in hand specimen is largely grossular. |
