The Jervis Inlet Property lies within the Coast Plutonic Complex along its
western boundary with the insular belt. The Coast Complex consists mainly of
quartz diorites, granodiorites, gneisses and migmatites enclosing numerous
elongated NW trending belts of volcanics and sediments.
The age of the intrusives in the southern part of the Coast Mountains ranges
from 75 to 158 my (Price et. al., 1981), whereas pendant rocks are generally
referred to as Jurassic Kretaceous. The Skwim Lake pendant lying within the
Coast Pluto& Complex, is dominated by weakly metamorphosed elastic sediments and
tuffs.
The pendant rocks are believed to be, in part at least, Lower Jurassic in age,
based on the presence of ammonites, identified as Arnioceras Kwakiutiarus by
H.W. Tipper of the G.S.C. Faunal evidence suggests the Skwim Pendant
stratigraphy to be time equivalent to the Bonanza Group of Vancouver Island
(Riccio et. al., 1983).
All rock units are near vertical and strike in a north to northwest direction.
Structural deformation has been intense with the early development of tight
steeply to moderately (60-20") north plunging folds. Locally developed isoclinal
folds may indicate an earlier period of folding. Late open style folds disrupt
earlier phase folds and cleavages. Two shear directions predominate. One is sub-
parallel to regional banding and is generally parallel to the penetrative
foliation while a second set of shearing strikes 060" to 100" and is steeply
dipping. Both appear to locally control zones of massive sulfide mineralization
in the vicinities of the Upper and Lower Adits on the Fury claims (Riccio et.
al., 1983).
