The soil in Cambuslang was a light loam, suitable for cultivation, but its mineral reserves are what brought modern prosperity. There was a limestone so fine as to be called "Cambuslang marble". This is capable of a very high polish. A good example can be seen in an 18th-century fireplace in the Duke of Hamilton’s old hunting lodge at Chatelherault Country Park near Hamilton. (James Hamilton, 2nd Earl of Arran, was granted the title of Duc de Châtellerault in 1548 for his part in arranging the marriage of Mary, Queen of Scots, to Francis, Dauphin of France). However, coal was mined from the 16th century and ironstone from the 18th, and it was these that brought industrial wealth.
