known as "Pope's Cradle", oeeeccecesn, this great limestone band can
be traced by the eye, forming a broad belt of whito rocky ridges, or
isolated hillg, for a distance of not less than thirty-five or forty
milos on a bearing E.S.E., and NW, Looking down upon it from
Pope's Cradle, it has tho appearance of a hogged-back rugged and
broken ridgo, winding through the country", This grey limestone
generally weathers to a paler groy or white, and in many places

has a very irregular surface duc to the presence of silicificd
portions that stand out on the weathered surfaco. Tho limestone,
which occupies an area of 15 square miles at tho wost ond of Stuart
and Trembleur Lakes, is usually crystalline and dark in colour,

some boing black due to the prescenco of a large amount of argillaccous
material.

Mcetamorphism. The Carboniferous rocks are metamorphosed at and
noar their contacts with the larger bodies of Mesozoic (7?) acid
intrusives, These contact zones of metamorphic rocks vary in width
from 500 yards to 2 miles, the widest being found around the acid
intrusives outcropping near Babine Lake. In these zones tho thinly
bedded cherts arc bleached and recrystallized, and their argillaceous
partings are changed to biotite. The argillites are metamorphosed

to slate, graphite schist, biotite schist, and quartz-biotite schist,
and the limestones are recrystallized. The andesite grecenstones

have been changed to chlorite and hornblende schists,

The zone of metamorphism around the granodiorite body
north of Stuart Lake is representative of the above. The order of
occurrence there is as follows:

Argillite

Slate

Graphite schist
Biotite schist

Quartz biotite schist
Augen gneiss

Intricately folded hornblende-feldspar gneisses and banded sodiments
are exceptionally well developed near the Radio Gold Mine property.
The Carboniferous rock types from which these were formed is
uncertain.
