Extract

There exists in the Lake District a peculiar type of metamorphism of which no analogue has, as far as the writer is aware, been described elsewhere, with the exception, perhaps, of South America. It is indicated chiefly by the presence of garnets and 'streaks ', the former being found indifferently in every variety of igneous rock of the district, the latter being mainly confined to the rhyolites or quartzkeratophyres. The most similar known to the writer is at Oyacachi in Ecuador, whence veto Rath has described flow-brecciated soda-rhyolites which sometimes contain red garnets. He also refers to rocks which may be 'streaky'.
