Hawkesbury Island is underlain mainly by Permian (?) and/or older metasediments within the Central Gneiss Complex. On Hawkesbury Island, south of Prince Rupert, kyanite-staurolite-almandine schists are exposed with sericite-epidote schist, gneiss and amphibolite. The individual kyanite-staurolite-almandine garnet schists may vary from one metre to over 30 metres in thickness and are traceable along strike for up to 2 kilometres (Area 2, Figure 10, Open File 1988-26). These schists contain up to 20 per cent almandine garnet and up to 20 per cent kyanite (Money, 1959). The garnet is present as subhedral to euhedral grains ranging up to 5 centimetres in diameter or as an- hedral rounded aggregates about 7.5 centimetres in size. The kyanite may be extremely coarse with blades that reach 20 centimetres by 1 centimetre in size. Sillimanite is reported from only one locality on Hawkesbury Island (refer to 103H 058).
