Characteristic gradational, centimetre-scale pegmatitic patches with large amphibole and feldspar crystals have widely varying alkali feldspar/plagioclase ratios, and may contain a significant amount of quartz.
Contacts between these units appear to be gradational, implying that they formed as a result of differentiation processes in a single parent magma.
The new age presented here for the Dipper Harbour Formation also constrains the age of the Musquash Harbour and similar plutons in the area because of the gradational relationship between the volcanic and plutonic units in the Dipper Harbour area.
