Taranofsky

You gave me good advice, and it turn out I was right to be confused (the caldera lies close to a fault)

but it turns out the impact craters has no more remnant physical data, but that it is simply an immense depression,

morphed by the destructive force beyond 'repair' by new crust forming, and actually leaving a measurable changes in gravity to be detected.

If that doesn't sound right to you, let me know, but it clears some things up for me.

Are these rocks off the Yucatan peninsula oceanic, or continental?

If they are continental, do continental rocks generally get significantly subducted?

If they are oceanic, what age are they?

What is the age of the impact crater?

Globally are more impact craters found in oceanic or continental crust?

What is the age of the oldest oceanic crust?

What is the age of the oldest confirmed continental impact crater?

 

If you can answer these questions (happy googling) then you will have the answer to your own question. Ask specifics if you are having any difficulties.

effing craters: how do they work?

just kidding.

but seriously…I think we're all familiar with the method of plate tectonics

if the continents drifted apart over millions of years

creating new crust in their wake

why are there those massive craters left over from millions of years ago, like the one off the coast of the Yucatán Peninsula? Shouldn't the new crust have filled that in?

help me out with this, thanks, I keep wondering about it

I'm Taranofsky, and I like geology

I morbidly watch endless videos of tsunamis, volcanic eruptions, earthquakes, sinkholes, etc

they fascinate me. Also I want to know every detail know about evolution.
