... and Archambault (1987) interpreted poorly dated dykes within the Otish Basin as feeders for the Otish sills. Beyond the Otish Basin, they proposed a correlation with a swarm of northeast-trending dykes of regional extent. Prior to the present study, Otish Gabbro sills and dykes were thought to have been...

Chown; Guy Archambault Abstract The Otish gabbro sills intrude Aphebian clastic rocks lying uncanformably on the Archean rocks of the Superior Province close to its juncture with the Grenville Province. The sills are undated but by inference may be ca. 1750 Ma. Two dyke swarms are known...

The area is weakly deformed even though it was subjected to several tectonic episodes ( Daigneault and Archambault 1990 ). Early normal-sinistral...
