Charlevoix crater
From Wikipedia, the free encyclopedia
Charlevoix is an impact crater in Quebec, Canada. It is 54 km in diameter and the age is estimated to be 342 ± 15 million years (Mississippian). The crater is exposed to the surface.
It is filled with shatter cones, PDF in quartz and feldspar grains.
It is a multi-ringed basin with a central uplift. Part of the crater is covered by the St. Lawrence River. It was discovered to be a meteor crater in 1965 after the discovery of many shatter cones in the area. Only a semi-circle of the crater is left due to the other half being flooded.
