Caption: | Dolomitic limestone. Muiredge, 2 miles north of Anstruther. Fife Region. |
Description: | Flaggy earthy brown dolomite with streaks of calcite. Composed of a great number of small shells, preserved in turbid ferriferous dolomite, all lying parallel to the bedding and cemented by irregularly oil-stained fine-grained carbonate which is largely a ferriferous dolomite, with varying content of ferrodolomite but never pure dolomite. Scarce granules of sideritic carbonate of high refractive index are distributed through the fine-grained carbonate; finely divided clay material occurs in shell casts, and some phosphatic fragments and grains of pyrite are present. Heavy yellow oil is evolved from the powdered rock on heating in a closed tube. Ferriferous dolomite, bituminous, micrograined, microzoichnic, bedded. SL0032. Britrocks S34454(a). Magnification x40. Light PPL. |
