Notes:
"Whitish quartzite with pebble beds" (GSI). "At the northern extremity of Inishowen there is a very quartzose gneiss with subordinate micalytes and hornblendytes (Metamorphosed Cambrian (?)), which to the southward, are overlaid unconformably by quartzites (Ordivicians (?)). The typical gneiss to the westward is remarkable, as the foliation therein is horizontal. The quartzitic gneiss is all more or less flaggy, and suitable for building purposes, and some veins of it are flags." (Kinahan, 1889, p. 458)References
