AbstractThe Charlevoix area, located 100 km northeast of Quebec City, was the site of a meteoritic impact some 350 million years ago. Few studies have documented the tectonic event sequence of this area before and after the impact. Some field observations suggest that the actual fault systems in the Charlevoix area could have been induced during the rifting of the Iapetan Ocean during Late Proterozoic and Early Cambrian. In addition, those faults could have been reactivated during the meteorite impact and even in Mesozoic time due to rifting of the Atlantic Ocean. However, relationships between the inferred impact cratering with structures left by the Iapetan rifting and/or Mesozoic reactivation have still to be documented.
