Will someone tell me about that crater?

AI Thread Summary
A large circular formation at the northern tip of South America, visible only from satellite images, is speculated to be an ancient impact crater. Initially thought to be the Chicxulub crater linked to the extinction of dinosaurs, recent discussions suggest skepticism about its classification as an impact site. Critics argue that the extensive sedimentation and tectonic activity over the past 63 million years would have significantly altered or buried the crater, making it unlikely to retain its original shape. Additionally, the crater's location relative to tectonic boundaries raises further doubts about its preservation. Some observations indicate it may be situated away from areas of recent tectonic deformation, which could support its status as an ancient geological feature rather than an impact crater.

At the northern tip of South America there appears to be a gigantic circular 'crater' dating back millions of years that is only visible from satellite images.

How old? what is it? Its effect?
Any info please.

thanks,
Ian.

That supposed impact crater is mostly beneath the sea but also appears on land. If it were somewhere else I might accept it as an impact crater, but due to it's geographic location it simply cannot be the remnant of an impact.
 
What's the problem? 63 million years of sedimentation and tectonics is more than enough to build complete mountains on top of it, burying it completely.
 
Yeah that's right, 60 million years of sedimentation to cover it and 60 milliion years of tectonic motion to break it up. The crater lies on a collision boundary so tectonics should have broken it up not preserved it. It should be severely mis-shapen after all that time.

Actually, from what I can see, it is quite a distance from the nearest boundary, and outside of the regions of recent tectonic deformation.

Thread 'Could an external cosmic body have influenced Earth’s geology?'

Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...

Thread 'The Secrets of Prof. Verschure's Rosetta Stones'

(Edit: since the thread title was changed, this first sentence is too cryptic: the original title referred to a Tool song....) Besides being a favorite song by a favorite band, the thread title is a straightforward play on words. This summer, as a present to myself for being promoted, I purchased a collection of thin sections that I believe comprise the research materials of Prof. Rob Verschure, who at the time was faculty in the Geological Institute in Amsterdam. What changed this...
