Part 2 of a series of photographs taken at Fourchu Head on Cape Breton Island in Nova Scotia, Canada, showing details of rocky outcrops, boulders, beach stones, and pebbles composed of very ancient Neoproterozoic volcanic rock.

  1. I was surprised by the predominance of the purple and green colours. The green reminds me of the green gabbro in intrusive dykes that I saw elsewhere along this stretch of coast at Rochefort Point. The purple could be from welded tuff that is created when the volcanic ash is so hot as it descends through the air that the particles melt together when they land. There were examples of welded tuff near Louisbourg Lighthouse.
