Shoal Lake Property<br />
Several smaller, stratabound, northeast-trending felsite sills intrude the<br />
lower maficultramafic series in the northeast portion of the northern Shoal<br />
Lake area .<br />
Two syn- to post-tectonic granitoid bodies intrude the volcanic succession.<br />
The Canoe Lake quartz diorite stock intrudes the lower mafic-ultramafic<br />
series approximately six kilometres northeast of the Shoal Lake West<br />
Project. Much of the stock is devoid of any foliation; however, a weak<br />
foliation is developed within the margin of the intrusion and several faults<br />
which have developed in the volcanics have been traced into the margin<br />
of the intrusion. The Snowshoe Bay Batholith intrudes the volcanic<br />
succession approximately one kilometre west of the Shoal Lake West<br />
Project and extends west into Manitoba. This medium-grained granodiorite<br />
intrusion is fairly homogeneous, although grain size and colour variations<br />
occur. A weak foliation or gneissosity is developed proximal and<br />
subparallel to the margins of the intrusion. This foliation appears to trend<br />
into the regional foliation, indicating that the intrusion may be syntectonic .<br />
Quartz porphyry, quartz-feldspar porphyry and felsite dikes occur<br />
throughout the area and have been observed in a variety of crosscutting<br />
relationships. Lamprophyre dikes have been observed to cut across all<br />
lithologies, but were not recognized in either of the late intrusions .<br />
STRUCTURE<br />
Foliations in the Shoal Lake area tend to diverge about diapiric intrusions<br />
and form several distinctive zones of high strain. All recognized foliations<br />
are interpreted to have developed during the D2 event .<br />
The Crowduck Lake - Witch Bay Shear Zone is a major east-trending<br />
zone of high strain tangential to the Canoe Lake Stock, Viola Lake Stock<br />
and the eastern lobe of the Dryberry Batholith. Relative horizontal<br />
movement is interpreted to be dextral. The orientation of the fabrics and<br />
the dextral sense of shear are consistent with a regional, northwesterly<br />
compression (Schwertner eta/., 1979). To the south of the Crowduck Lake<br />
- Witch Bay Shear Zone, a shadow zone, in which little strain is observed,<br />
is indicated on the southwestern flank of the Canoe Lake Stock .<br />
Several narrow, northeast-trending high strain zones occur between the<br />
Snowshoe Bay Batholith and the Canoe Lake Stock. These are developed<br />
within and along the margins of the Stevens Island Complex and trend<br />
subparallel to the intrusion boundaries. These zones of high strain define<br />
three shear zones, with similar orientations and character which suggest<br />
that each is a component of a larger deformation zone referred to<br />
as the Shoal Lake Deformation Zone. The westernmost of these shear<br />
zones contains the Duport mineralized zones and has been termed the<br />
Duport Deformation Zone. The central and eastern zones are termed the<br />
