Manicouagan Impact Structure
Monday, 11. February 2008, 19:04:08
The Manicouagan crater was formed by the impact of a 5 km diameter asteroid which excavated a crater originally about 100 km wide although erosion and deposition of sediments have since reduced the visible diameter to about 72 km. It is the fifth largest impact crater known on earth. Geologists used to think the Manicouagan impact caused the Triassic-Jurassic extinction 200 million years ago. Recent U-Pb zircon dating of the impact melt proved that the crater has an age of 214 ± 1 million years. As this is 12 ± 2 million years before the end of the Triassic, the crater cannot be the cause of the Triassic-Jurassic extinction event.
Recently, the completion of the Manicouagan Dam filled the annular moat to its present depth creating a circular reservoir for hydroelectric power. This circular lake accentuates the contour of the eroded impact-brecciated ring area of the crater.
If you are in for some really weird pseudoscience the “Thunderbolts” people have an alternative explanation for this (and a few other) impact craters. But first let me quote the introduction to the “Thunderbolts pages” ‘“From the smallest particle to the largest galactic formation, a web of electrical circuitry connects and unifies all of nature, organizing galaxies, energizing stars, giving birth to planets and, on our own world, controlling weather and animating biological organisms. There are no isolated islands in an electric universe". David Talbott and Wallace Thornhill - Thunderbolts of the Gods’. Now, don’t say that I didn’t warn you.
Electrical scarring as explanation (sic). So the Manicouagan crater is simply the scar of a cosmic thunderbolt, wel, well! Is The Electric Universe a bold new theory that overthrows the scientific establishment’s dogmas about cosmology? Or is it just another crackpot idea? If you ask me, those people must be stark raving mad.
Pseudoscience may be defined as a body of knowledge, methodology, belief, or practice that is claimed to be scientific or made to appear scientific, but does not adhere to the scientific method, lacks supporting evidence or plausibility, or otherwise lacks scientific status. The term comes from the Greek root pseudo- (false or pretending) and "science" (from Latin scientia, meaning "knowledge").

It is interesting that often a trap-maker eruption happends at the same time of rhe mass extinction (but also a meteor crater is more or less "in time".
So I prefere the trap explanation, also for tje K/T extinction (Deccan traps)

Anyway I am not an expert, just an interested listener.
