Geology

Data sheet of the meteoritic crater of Charlevoix

World champion of the large terrestrial craters for its qualities of conservation and observation

  • Located on northern bank of the St. Lawrence, with 100 km in the North-East of the town of Quebec. Meteoritic crater recognized by the geological Commission of Canada.
  • Age: 350 million years (more or less 20 million years).
  • Diameter: 56 km. Among 10 larger of the world.
  • Discovered in 1965 per Mr. Jehan Rondot then geologist with the Ministry for the Natural wealths.
  • First world crater discovered by the shattercônes (conical fracturings in the rock due to the passage of the shock wave in the earth's crust).
  • the meteorite at the origin of the formation of the crater of Charlevoix was probably an asteroid which had a diameter estimated at 2 km, weighed 15 billion tons and arrived at cosmic 10 to 20 km/seconde (roughly 60.000 km per hour!).
  • Energy released at the time of the impact: 20 million megatons of TNT, is thousands of times the combined power of all the nuclear arsenals.
  • In the center of the crater, halfway between Bay-Saint-Paul and Malbaie, culminates the mount of the Crumblings, with 768 meters of altitude. This central sprouting is the result of formidable raising (or " rebondissement") bottom of the crater immediately after the impact.
