| Caption: | Charlestown Main Limestone, 6-9 feet above base of quarry face.Chapel Limestone Quarry, about 2 miles north-west of Kirkcaldy. Fife Region. |
| Description: | Dull grey limestone with numerous white spots and scarcer pale green spots, and with a band in which a greenish mineral is more abundant than calcite and is streaked out parallel to the band. The limestone is composed of granular calcite, 0.02 mm - 0.6 mm grain-size, together with numerous large grains representing crinoid ossicles. Relict organic structures are preserved by outlines in clay, and shapeless masses of opaque clay are abundant. Also aggregates of translucent cryptocrystalline, moderately birefringent material are common. No datolite or garnet was seen. The white spots seen in the specimen are not pectolite, but a finely divided flaky aggregate of moderate birefringence, perhaps talc. Limestone with talc, varigrained, zoophasmic. SL0213. Britrocks S35903. Magnification x40. Light XPL. |
