Some of Dal Purcell's the stone came from the old Dalhousie (Bluestone) quarry at Cove DAL Purcell's Cove, and some probably also came from the CN railway cut, which was under construction at the same time as some of the older buildings on campus. Many buildings also containquartzite blocks from the Cambrian Goldenville Formation, which underlies the Halifax Formation. Light brown Carboniferoussandstone quarried at Wallace, Nova Scotia, was used for columns and other decorative stonework(front) . Granite blocks used for steps, gateposts, and paving stones came from a second quarry in the hills behind Purcell's Cove. e.
