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.
