Geological Features of the Frontenac Arch

As discussed in the Geological History section, the Frontenac Arch is made up of older rock from the Neo- to Mesoproterozoic  Era (the event of the Rodinia supercontinent ).  The surrounding areas to the East and West of the Frontenac Arch are much younger rocks from the Paleozoic Era.  You can explore the rock types and faults lines present on the Frontenac Arch landscape through our maps available on the right-hand side (click view map to see the interactive version and click features to display background information).
