Caption: Limestone from Loch Thom, Renfrewshire.
Description: A banded pale limestone from the Upper Old Red Sandstone (Devonian). The Inverkip, Gourock, Loch Thom area is known for its nodular concretionary limestones of Devonian age. British Geological Survey Petrology Collection sample number MC 7546. The quarries are not now worked but historical records exist, for instance in the nearby Inverkip area, nodular conglomeratic limestone, with pebbles of quartz, was at one time worked and calcined at old quarries and kilns a little west-south-west of Inverkip House. The calcareous portion is concentrated into nodules, and these were sufficiently abundant to allow of the bed being worked as a whole. Montgomery (1839) described it as a 'bed of limestone, 8 to 10 feet thick, which has been wrought to a considerable extent'.
