| Caption: | Limestone from Broadford, Skye, Invernessshire. |
| Description: | A white, grey-mottled, altered limestone (marble) of aphanitic aspect. The limestone is Cambro-Ordovician Durness Limestone, Group II, Eilean Dubh, that has undergone contact metamorphism. It is from an old marble quarry, 14 miles north-west of Broadford church, Skye. BGS Sample SL 245. British Geological Survey Petrology Collection sample number MC 7635. White marble, veined in places with grey and yellow. This locality is one of a number, between Camas na Sgianadin and the Broadford River a mile and a half farther south, in which the Durness Limestone has been invaded by gabbro. The magnesia content of the marble is very variable but appears to be high in some places. In thin section the analysed specimen consists of interlocking grains of calcite, about 0.5 mm. across, which enclose or interlock with aggregates of flaky brucite pseudomorphous after periclase. Forsterite is also present. In 1949 it was recorded that there were dumps at the old quarry containing several hundreds of tons of clean marble, and considerable reserves occur in the vicinity. |
