| Description: | Banded crystalline limestone with small sulphides from Baluachraig, probably from the Baluachraig Quarry on the north-east side of the main road, 270 yards south-east of Baluachraig which lies one and a quarter miles south by west of Kilmartin, Argyllshire. BGS Sample SL 125. British Geological Survey Petrology Collection sample number MC 7585. The limestone in the quarry is very variable in grain, and in the coarsest beds there are pebbles of quartz and feldspar up to half an inch in length in a matrix of calcite. The limestone dips west 30 degrees north at 70 degrees, and is at least 180 feet thick. The quarry face was recorded as 15 feet high with no overburden, and as being in a disused state. There are considerable reserves up the hillside to the east. The specimen collected from the quarry showed on analysis: calcium carbonate 66.44 per cent, magnesium 0.55 per cent, insoluble residue 32.05 per cent. |
