South African dude here. I was born inside that crater and my family still own farmland in it. It's way too big to even identify as a crater until you explore the mapping. Arguments have raged for several years now with people speculating that region of SA having had the worlds largest reserves of gold and platinum group metals due to the impact penetrating the crust so deeply and ejecting deep Earth material to the surface.

It seems that the force of impact may also explain the presence of diamonds as well considering that they are the product of carbon under intense heat and pressure that would have been created by a meteor strike.

This is true. The original metals formed with the Earth all melted and sank into the core. All the ore we mine within a few miles of the surface that isn't volcanic, was deposited later from asteroid impacts. This is also where Canada gets its vast nickel deposits from

As someone from Sudbury, one thing is i can assure that this town would not exist if that asteroid didn't hit, almost a complete mining economy here. Great vid!

Awesome video, thank you. It should be said that water covers about 70% of the earth's surface, so we are only seeing about 30% of the impact signatures. I'm sure there were a lot of impacts on ice sheets that melted away as glaciers receded too. We're only seeing a small fraction of impacts that have happened.

South Africa contains the Kaapvaal craton which is some of the oldest and most stable rock on the planet (it's more than 3 billion years old). Our geology is actually pretty interesting due to how extensive the geological record of the craton is given its age and its erosion resistance due to the arid climate of the region- although I recognise how "interesting geology" may sound like a bit of an oxymoron.

An extremely good video, presenting data in a well organized way. I like that only 'craters' that are well accepted by the scientific community are presented. A couple of interesting craters that I would have liked to see presented are: 1. The Chesapeake Bay impact helped form a bay that has been very important in American history. 2. The Cumberland Gap impact helped create the easiest path through the Appalachian Mountains, rediscovered by Danial Boone. This speeded up the Western Expansion of the settlers, getting them across the biggest physical mountain barrier to Western Expansion, greater than the Rocky Mountains, curiously enough. Another historically important impact.

Born, raise, and spent most of the life in Hampton and everyone can tell where the outer rim of the Chesapeake Bay Impact Crater is. Inside the crater, the ground water is so salty and disgusting that one can't even water the grass without risk of killing it. Just a couple of miles outside, the ground water is fine. Outside some iron, the ground water is actually safe to drink and use.

I read that the tsunami created by the Chesapeake Bay impact reached as far inland as the Blue Ridge mountains. Further north on the Atlantic coast is the Toms Canyon impact site, at the mouth of Toms River in NJ, where the river meets the ocean, and may have happened at the same time as the Chesapeake event.

@b.a.erlebacher1139

Is there evidence of the Cumberland Gap being caused by an impact? AFAIK, it's a classic example of how rivers can maintain a pass by eroding their beds as fast as the mountains around them rise.

Informative but also brief and to the point. Thanks for doing this.

Interesting video; but I noticed that there was only one described crater which is under water. I assume that a meteor which strikes our planet is just as likely to hit any given spot on the planet, whether is it covered by water or not, and since about 70% of our planet is covered by oceans (not to mention the ice sheets which still or once covered major areas), the number of major hits our planet has taken may be much greater than what the land-based craters indicate.

Indeed, but most oceanic craters disappear as oceanic crust is subducted. Pretty much all of the world's oceanic crust was created no more than 200 million years ago, so older impacts were purged from the record.

@Daneelro

Ай бұрын

There are multiple reasons for fewer known oceanic impact craters in spite of more area. One is that smaller impactors only form a very short-lived temporary crater in the ocean water. If that happens, all you can detect geologically is tsunami deposits and, if you're lucky, some seafloor deposits. There is one well-known example: the Eltanin impact 2.5 million years ago in the southwest Pacific off Chile (look it up). So only larger impacts produce a crater on the seafloor. A second reason is, obviously, that it is more difficult for geologists to explore the seafloor. A third reason was already named by drex6347: seafloors get subducted and thus are generally much younger than continental crust.

@MariaMartinez-researcher

Ай бұрын

Also, considering how little of the ocean floor has been mapped, how difficult is to reach it, and how difficult would be to notice a large crater covered by marine life in shallow depth or in the darkness of abyssal depth, finding any submarine craters at all would be an exploit.
