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.
