International audience Heat flow measurements in 4 deep drillholes near Voisey Bay, Labrador, have yielded the lowest value ever reported in the Canadian Shield, 22 mW m -2 . This very reliable estimate is also one of the lowest continental heat flow values world wide. It requires the crust to be ve...
