Greenland Group

One of the most widespread rock units on the western side of the South Island is the Greenland Group – a thick, uniform sequence of quartzose greywacke and argillite, deposited in earliest Ordovician time (about 490 million years ago). This photograph was taken at Seventeen Mile Bluff, on the coast north of Greymouth.
