Volcanic Tuff Louisbourg Lighthouse 8

Volcanic bomb embedded in tuff

Volcanic Tuff Louisbourg Lighthouse 8 – Detail of texture in volcanic tuff rock dating from the Neoproterozoic 575 million years ago. The rock is consolidated volcanic ash with mostly minor fragments, and was photographed on the Cape Breton coast in Nova Scotia, at Louisbourg. The large rounded embedded inclusion is a volcanic bomb that formed when a piece of molten lava was also spewed out of the vent and landed in the soft ash below the volcano.
