Lesson plan

Bluestone

bluestones. These dolerite slabs, split by frost action, seem to be stacked ready for the taking, and many have been removed over the centuries for local use. Research favours the theory that humans also transported stones from Carn Menyn to build Stonehenge, about 250 km away. Bluestone is a cultural or commercial name for a number of natural dimension or building stone varieties, including: * basalt in Victoria, Australia, and in New Zealand * dolerites in Tasmania, Australia; and in Britain (including Stonehenge) * feldspathic sandstone in the US and Canada * limestone in the Shenandoah Valley in the US, from the Hainaut quarries in Soignies, Belgium, and from quarries in County Carlow, County Galway and County Kilkenny in Ireland * slate in South Australia It is unrelated to human-made blue brick.
