Geology of the Vedder Mountain Silver Lake area Hillhouse, Douglas Neil
Abstract
The major rock units within the area investigated are the Permian Chilliwack Group, the Upper Lower Jurassic - lower Middle Jurassic Cultus Formation, and the Upper Jurassic Lower Cretaceous Vedder Mountain Sediments. The Chilliwack rocks examined consist of four limestone units, a thick volcanic sequence, a conglomerate and argillites. The Cultus rocks consist of argillite, shale, graywacke and clastic limestone, The Vedder Mountain Sediments are graywackes, argillites and conglomerates. A tabular body of igneous rock and a schistose cherty rock are included in the sequence. The regional strike is to the north-east. Most of the rocks in the area are strongly fractured. The Cultus Formation is folded into a series of overturned isoclinal folds with axial planes striking north east and dipping south east. The strongly folded Chilliwack rocks are thrust over the Cultus rocks from the south and south east. The relationship of the Vedder Mountain sediments to the other major rock units is unknown.

Description |
The major rock units within the area investigated
are the Permian Chilliwack Group, the Upper Lower Jurassic -
lower Middle Jurassic Cultus Formation, and the Upper Jurassic
Lower Cretaceous Vedder Mountain Sediments. The Chilliwack
rocks examined consist of four limestone units, a thick
volcanic sequence, a conglomerate and argillites. The
Cultus rocks consist of argillite, shale, graywacke and
clastic limestone, The Vedder Mountain Sediments are graywackes,
argillites and conglomerates. A tabular body of
igneous rock and a schistose cherty rock are included in
the sequence.
The regional strike is to the north-east. Most
of the rocks in the area are strongly fractured. The Cultus
Formation is folded into a series of overturned isoclinal
folds with axial planes striking north east and dipping south
east. The strongly folded Chilliwack rocks are thrust over
the Cultus rocks from the south and south east. The relationship
of the Vedder Mountain sediments to the other major
rock units is unknown.
