STOP 12
This stop illustrates tight drag folding in a unit composed
of interbedded fine grained clastic sediments, jasper, and
hematite—rnagnetite layers.
Note If collecting specimens, please do not mar the
the crenulated section of the southern exposure.
Most of the "mineral showings" near the mine have ben
covered with waste rock from underground workings.
Keep away from fenced off areas. Continue west on
Highway 580. (Highway can be reached by following service
road, or by backtracking).

ExcelJent exposures of pillow lava, anygdaloidal lava an4
volcanic breccia can be found along the shore in this
vicinity, and on the nearby islands.
Pillow breccia may be observed along the waterline
of the northern tip of the peninsula. Here well packed
pillow lava grades into breccia containing isolatedpillows.
This occurrence is similar to pillow breccia described
by Henderson (1953), Henderson and Brown (1966) and
Carlisle (1963)

This Stop illustrates age relationships between two of
the Proterozoic diabase intrusives, as well as their
lithological differences.
