| Caption: | Charlestown Main (Seafield Tower) Limestone, lowest 34 ft. Shore south of Seafield Tower, Kirkcaldy. Fife Region. |
| Description: | A brown, compact, microcrystalline dolomite showing slight overall effervescence in cold dilute HCl. Crinoid ossicles unaffected by cold dilute HCl are scattered in the rock. In thin section the rock is a dolomite of very variable grain, parts being of 0.1 mm grain-size and cemented by limonitic clay, most being about 0.2 mm grain-size, but large areas show recrystallized dolomite of grain 0.5 - 1.0 mm across. In this rock there is much more disseminated limonite (or limonitic clay) than in S 35802, and because of original impurities having impregnated the carbonate of the crinoids, the trabecular structure is extensively preserved in spite of the dolomitization, which may have completely destroyed all other evidence, including shape. Dolomite, varigrained, zoophasmic, diacrystallic, homoiolithic. SL0280. Britrocks S35803. Magnification x40. Light XPL. |
