ABSTRACT
On the eastern portion of the Burlington Peninsula of northwest central Newfoundland, Canada, there are two different age groups of volcanic and volcaniclastic rocks. There have been arguments in the past as to whether or not these two groups are actually only one group (Cape St. John Group) but with progressive intensity of deformation and metamorphism from south to north. Other workers have divided the rocks into two distinct groups, the Grand Cove Group and the Cape St. John Group based on their differences in deformation style and metamorphic grade. This study ignored previous divisions of the rocks into one group or the other and instead described the lithologies of the rocks in detail. Two distinct groups of rocks were defined, the Northern Group and the Southern Group, based on lithological and structural differences. The Northern Group is Early Ordovician in age and outcrops along the northern coastal areas and inland southwards towards the La Scie Highway. These rocks are complexly deformed and metamophosed to the actinolite-greenschist facies. The Southern Group is Silurian-Devonian in age and outcrops in the southern central portion of the Peninsula. This group is only mildly deformed and metamorphosed to lower greenshist facies. Both Groups were metamorphosed in Late Devonian/Early Carboniferous (Acadian Orogeny). This study revealed previously unrecognized ductile high strain zones which form a definite restricted belt across the Peninsula separating the Northern Group from the Southern Group.
