Caption: | Charlestown Main Limestone, top 7 feet in north-west corner of West Quarry, Charlestown Quarries, 3 miles south-west of Dunfermline. Fife Region. |
Description: | A brownish, compact dolomitized limestone, having a crystalline appearance due to the abundance of crinoid plates. It is composed of fossil debris consisting essentially of crinoidal and polyzoan fragments; subordinate fossil components include shells, spines, foraminifera, siliceous spicules and scarce phosphatic fragments. Parts of the rock are completely dolomitized; in other parts, while the matrix is recrystallized in dolomite and partly replaced by quartz, the larger fossil structures remain wholly or in part of calcite. Limestone, dolomitic, fossiliferous, clastizoic. SL0276. Britrocks S35799A. Magnification x40. Light XPL. |
