Strike slip faults
Strike slip faults. Here gravity is the middle principal stress and
the maximum principal stress is horizontal. The faults are vertical
horizontal slip -- strike slip. If you stand on one side of the fault
the opposite side appears to have moved to your right, the fault is
to as right-slip or dextral. If the slip is to the left, we call the
left-slip or sinistral.

The fault displaces the Giant Yellowknife ore body from the mine on

85_375. Great Glen Fault. Loch Ness; view northeast from Ft. Augustus.
Gouged out by glaciers, this fault zone crosses Scotland from Fort
William to Inverness. It is a late Paleozoic left lateral fault, whose
offset was determined by matching granites on either side of the glen.
