There's one crater that may be older than any that we know of. Except there's a snag, it might not actually be a crater at all.

An often repeated quote: Reality is far stranger than fiction. Even outside of science, several historal events would be belittled for terrible writing if in a book, like how Archduke Franz Ferdinand was assassinated. After being attacked his driver got lost and ended up stopping directly infront of the cafe his assassin had gone to for a sandwich to sulk about his failled attempt giving him a second chance. Like if i read that in a book and Franz was a main character i would have been outraged at just how contrived a death that was. And within science just read any fact about quantum mechanics and subatomic particle behavior and ask whats stranger, that or the Force in Star Wars.

Most "impact craters" are wrongly-classified as such. The grand majority of the Earth's craters are volcanic in nature.. including Meteor Crater in AZ. This is something the Earth has seen more often than not. Scientists are finally beginning to figure this out. It will be interesting to see how they handle the fact that 99% of lunar craters are not from impact. Should be entertaining to see the failure of an entire paradigm upon which "well-understood science" is based.

There were some MASSIVE shield volcanoes early in Earth's history, so it really makes you wonder if that's what this is. Some structures in Canada resulting from ancient giant shield volcanoes have some rather interesting geology in roughly circular patterns. The melted rock under high pressure could perhaps come from a giant ancient magma chamber or batholith, but it would also not fracture any zircons. This would of course also fit pretty well with the timing.

Wild guess: A large object impacted and then in three billion years, several miles of surface was removed by various processes, leaving only the bottom of the initial crater, or shocked rock that was below the crater. Since it is known that nearly three miles of sediment was somehow removed atop the Colorado plateaus, this makes sense to me. Another wild guess.... there is apparently a far larger structure like this on Mercury, opposite where a huge object sent a shock to the other side of the planet. Another wild guess: There is at least one place on Earth where there was an underground critical mass of radioactive elements, so maybe a detonation like that did it. Anyway, they need to drill or excavate to complete the picture.

This could also be explained by Immanuel Velikovsky's theory which underpins the "Electric Universe" position that plasma lightning bolts were exchanged between planetary bodies on close approach to one another. The overwhelming number of circular craters on the Moon for example, is said to be strong evidence that side swiping from space rocks was not the main cause of the cratering, and that electrical discharge always occurs orthogonal to any surface. The temperatures required to melt the Moon's or the Earths surface and transmute elements is more than catered for by such staggering electrical events. This is of course heresy, and has always attracted ridicule, but presentation and discoveries like this one, still speak loudly to the simplicity and diverse explanatory abilities of Velikovsky's theory, and the role of plasma and electrical activity in the cosmos.

Makes no sense. Zero evidence of an impact crater means zero impact of an impact crater. Scientists said it is either a cat or a dog. Initial reporting indicated it was a cat. Once utilizing much better technology and using a different approach they concluded it was a dog. It cannot be a catdog. Also, they initially thought it was a cat because it was a quadruped and showed the primary hallmarks of an impact crater. Just as Ubehebe appears to be an impact crater..but certainly is not.

It is a prominent, near-perfect circular arc, covering more than 160° of a 450-km-diameter circle.[1] While the circular shape has led to suggestions that it represents an impact crater, there is no evidence for this hypothesis, and it is thought to have been formed as a result of lithospheric flexure during the Trans-Hudson orogeny

It may be possible that this geological structure is both an impact crater and a volcanic crater, which would make it a very unique feature. I mean a meteor impacting directly into an active, or dormant, volcano is certainly going to affect the geologic composition of the resulting rock formations in the area in unique way. At least, that's what I think would have happened in order to explain both the existence of the pulverized rock, and the lack of impact stressed zircon crystals.

It struck me that the larger the asteroid impact, the less frequent. Many more, smaller ones over equal time? However, if a smaller one, thus more frequent, were to impact a volcanic or seismic instability (worst case, a mega volcano reservoir) geological effects could be much more significant, especially if fault lines were hit multiple times along their length, or magma reservoirs bracketed by multiple hits. The optimal rain of smaller bodies to produce, say the Siberian and Deccan Traps, can probably be calculated by others better qualified. This might help answer your “from above or from below” question. There remains the question of asteroids hitting deep ice or exploding overhead and their record trace. The potential reversal of Iceball Earth?

I wonder if there is an impact on the opposite side of the planet from it, or if when the magma levels lowered it pinched at the center.

Could it have been BOTH??? Think for a minute, the chances are super rare, but what IF it was a both? Maybe it got slammed by a meteor first, causing the bubble underneath to do its job.

The pulverisation could have been caused by a meteor strike, which then weakened the crust, making it easier for hot magma to uplift the area. That's my hypothesis!

So we should ask the real question, what hit the earth three billion years ago, to shatter the crust of the whole earth. How big have to be an impact to have such a large effect: 100 km to 500 km?

Is there any chance this is (not sure the following is actually the correct technical term, but I am running with it) Antipodal Chaotic Terrain? Also, I kinda suspect that the Deccan Traps are Antipodal Chaotic Terrain caused by the Chicxilub impact... not sure if that hunch holds up, though. If the Maniitsoq structure is ACT, then finding the associated impact crater would be amazing; unfortunately ocean-bottom crust is geologically recycled very quickly, so if it was in the ocean then chances are very high that the linked crater is long gone.

This could also be explained by Immanuel Velikovsky's theory which underpins the "Electric Universe" position that plasma lightning bolts were exchanged between planetary bodies on close approach to one another. The overwhelming number of circular craters on the Moon for example, is said to be strong evidence that side swiping from space rocks was not the main cause of the cratering, and that electrical discharge always occurs orthogonal to any surface. The temperatures required to melt the Moon's or the Earths surface and transmute elements is more than catered for by such staggering electrical events. This is of course heresy, and has always attracted ridicule, but presentation and discoveries like this one, still speak loudly to the simplicity and diverse explanatory abilities of Velikovsky's theory, and the role of plasma and electrical activity in the cosmos.

There is another possibility, that it is impact creator, but not from space. The dome of magma may have popped the cork so to speak. Sending a large mass of volcanic rock into the air. But it didn't have enough force to escape far. So most of it just crashed right back down into the volcanic crater after falling a great distance.
@eroraf8637
@eroraf8637 2 жыл бұрын
Nope, that’s just not possible. Interesting idea, but there’s no way for that to happen the way you described. If the magma dome did “pop its cork,” it would likely shatter that cork into much smaller fragments and fling them in all directions. Even if the majority of the cork remained intact, it simply wouldn’t be lofted high enough to come back down with enough force to create the shocked minerals.
