A positive contact test between Nipissing diabase and Gowganda argillites

A positive contact test between Gowganda argillites and Nipissing diabase indicates the shallowly inclined and southerly directed Nipissing remanence records a primary intrusive event. Contact tests on the steeply inclined Nipissing direction are also positive. Together these tests conclusively indicate there were two distinct phases of Nipissing intrusion. Limited evidence suggests that the sequence between these two events should be from the shallow to the steeply inclined direction, giving a pole path from south to north. This is in direct conflict with the presently accepted north to south trending Track 5.
