Whilst looking over maps of the wildfires in Canada, I noticed a circular formation about 150km across in north central Alberta, just north-northeast of Fort Vermilion. At first glance, from directly above, it looks like a crater, but on the elevation profile, it's 918m at the "peak", where the surrounding "rim" is 300-490m. I looked through your video history for any mention of it, but didn't find any. Any idea what this oddity is, and if there's any plan to cover it? Love your brief, but information-dense coverage of geology!

You're referring to the Caribou Mountains area. It's a Plateau (raised area of land) in north central Alberta. Doing some quick looking around I didn't see anything particularly conclusive, but Alberta does have a Geological Survey page you can look at. But If I had to throw my undergrad degree in geology at it, I'd hazard a guess that it represents what is left of a granite province exposed at the surface. This would essentially be the scoured remains of a solidified underground magma chamber (think a dome of lower rock pushing up through the layer of rock around it) which has been brought to the surface and ground down by glaciers. It remains higher than the surrounding terrain because the granite minerals that make it up are harder and more difficult to erode than what is around it. I'm guessing that there's a map somewhere on that Alberta Geological Survey site that will show the bedrock composition map... don't be surprised if it is all granite there. Exposed lava dome structures are the bane of existence for the hopeful Google Earth impact structure hunter : )

It appears probable that if the supposed impact site and trajectory of remaining buried core of the meteor, caused mass vocanic activity in a (unique to the continent) region, now located in the south east part of the Australian mainland, running North East to South West and further believe due to continental drift, this impact may have been the catalyst for the Great Dividing Range (approximate age circa post impact period). Imagine a continental plate grinding over a 'massive' foreign body, buried deep between the lower crust and upper mantle, some 28kms +/- deep, for example. Something both this large and deep enough through sheer velocity to potentially create a hotspot region beneath our tectonic plate. Something of this magnitude would definitely cause an upward effect, with and without volcanic activity, due to all related fracturing at the time.

Although asteroids contain high iridium levels, comets likely don’t since they contain more volatiles and less rocks. So if a comet caused the crater and not an asteroid, that would explain the lack of an iridium anomaly there. That said, it would have to be moving very fast to not be an air burst in that case, because all that ice is much easier to melt and vaporize than anything stony or metal-rich - although comets reach speeds high enough to overcome atmospheric friction all the time, so I digress.

Maybe this is a silly question, but is *every* asteroid higher in iridium than Earth's crust? I ask, because we know for certain already that there are plenty of asteroids which are considered "rocky," and many others which have a high concentration of metals - but even a look around the other rocky planets shows how different the chemical compositions of rocks are here than there. It was the similarity of Moon rocks to terrestrial basalts that gave weight to the impact theory of the Moon's formation - and the difference in that composition which allowed scientists to identify rocks on Earth which had originated on Mars. So we know that there are other bodies out there which also have low-iridium concentrations in their surface rocks, and statistical inference would suggest that there is an unequal distribution of iridium among metallic asteroids as well. Since the complex crater structure maps better to known impact craters than to any known volcanic events, I'm wondering if it's possible that the Deniliquin Structure may have been formed by a large celestial body which would have plotted into the low-content tail of of the iridium distribution bell curve.

The late Precambrian was very in terms of glaciation.

After those 2, there were a bunch of short-lived but intense glaciations such as the Gaskiers glaciaitions, the Facquier glaciations, and the Baykonurian glaciation. The latter may have kickstarted the Cambrian explosion!

It should be noted that Ordovician sediments have been shown to have a spike in Osmium and Helium 3 along with a sharp uptick in the rate of fossil meteorites (which are meteorite falls where the meteor becomes buried and re-mineralized over geological time) . Osmium is another rare platinum group metal so suggestive of an extraterrestrial impact event We also know that the bulk of these meteorites that fell at an increased rate since this time(they remain the most common meteorites to fall ever since) were a specific class of L Chondrites which due to their distinctive and well dated shocked quartz grains were part of a ~150+ km parent body asteroid which experienced a cataclysmic collisional break up event468 ± 0.3 million years ago in the main asteroid belt. Additionally based on the observations of the Kepler space telescope of what appear to be comparable events around other stars it has been noted that the peculiarities of the Ordovician periods Andean-Saharan Ice Age which some work claims to have evidence to suggest the glaciation had begun before the corresponding carbon dioxide drop rather than after as is seen with other glaciation events. In effect this would have worked as a result of the debris infalling from out beyond the orbit of Mars in a collisional cascade both pummeling the inner planets and as it falls within their respective orbits obscuring a few percent of sunlight. If a big chunk of the L chondrite parent body of the impactor which smashed into it hit the Earth that could do it. That said I personally suspect the age is much older than estimates if as someone pointed out Ediacaran biota have been recovered from this region which should have been obliterated by any such impact that would at the minimum age require any impactor to be no younger than around ~600 Ma in the Neoproterozoic based on the geologic law of superposition.

Unfortunately any comet would also be an undifferentiated body and thus we would expect an enrichment of siderophile elements such as Iridium and and other platinum group metals. Notably work has found Ordovician age sediments with an Osmium spike so any absence of Iridium becomes much more curious since an impact event should cause a spike for all such elements unless the parent body was for some unknown reason chemically depleted in one or more of those elements. Of course if as someone pointed out in the comments Ediacaran biota finds have been recovered from rocks within the potential crater, then the stratigraphic law of superposition in geology sets a hard lower limit for the age of any impact needing to be at least ~600+ million years old.

Not an ignorant question at all, and the answer can be both yes and no. I'm by no means an expert so take it with a grain of salt. It depends where the crater is and many variables. If it falls on or very near a fault line (meeting of tectonic plates) then it is quite possible for deforming to occur. Australia doesn't have any fault lines running through it, so it's unlikely that continental drift would deform a crater. Wind, rain and erosion will 'hide' it. But the evidence and 'structure' will remain mostly the same

You seem to have got Deniliquin right ( a place better known simply as "Denny" and written as "Denni"), but Albury is pronounced as "Allbree" not "Al-berry." If an asteroid struck this part of southern NSW/northern Victoria, please tell me how it is that it is so flat out there? I've driven through that area numerous times, so know something of the topography of the areas from western/north-western Victoria, through to well into southern NSW.

@Dragrath1
Жыл бұрын
@@JamieSteam Actually a metallic asteroid would have basically all the iridium since Iridium is a siderophile element, The Iridium works because for any undifferentiated impactor which is anything not a chunk of a shattered planet/dwarf planet since their siderophile elements haven't been able to sink to the core. Thus any comet or undifferentiated chondrite should by definition produce a spike of these siderophile elements even if these rare elements were a minor constituent of their bulk composition. SO the only things which can be ruled out(if this timing is indeed correct) is an undifferentiated (whether a comet or asteroid)or metallic asteroid. Of course there has actually been a positive result for a spike of another siderophile element Osmium for the Ordovician which is interesting. More data needed was one measurement faulty or could there have been some chemical quirk where an impactor was depleted in Iridium? (The choice of Iridium over other platinum group siderophile elements is historical convention related to the Chicxulub impact discovery)

A giant comet would have vitually no iridium and cause no shocked quartz. A comet is mostly made of various ices and carbon compounds. Such an impact would more closely resemble a titanic nuclear explosion without the metallic fallout of an asteroid. No shocked quartz since the comet vaporizes as it impacts the atmosphere and the earth's surface. It still produces a crater simply from the force of vapor explosion. One large enough to make a crater 200 miles across would have to be 2 to 3 times larger than the 6 to 10 mile wide Chicxilub meteor.

The Gravitational attraction of the Earth is 6 times that of the Moon. So if you want to get an idea of how many, and how big the meteors that have hit the Earth have been, look at the Moon. It a perfect analogue. But just multiply the quantity and size of the meteor impacts by 6.

@lordsrednuas
Жыл бұрын
There are two main things that can change magnetism in rocks naturally, temperature and physical shock. In fact you can play around with the shock side of things yourself fairly easily, get yourself an iron bar, and hit an end really hard, you will make it into a magnet (not a very strong one but still a magnet), hit it again and you will de-magnetise it. While the magnetism found in most rock layers isn't so easy to manipulate (due to the lower concentration of magnetic particles), a meteorite is a much bigger hammer. Heat on the other hand tends to de-magnetise, melt your magnets and when they cool they won't be magnets anymore. Big impacts obviously create a bunch of heat, a whole lot of rock gets vaporised, but it's still pretty warm outside of that area. So we have an interplay of a big shockwave magnetising everything, and a wave of heat de-magnetising everything. And it turns out the physical shockwave tends to be significant a bit further than the heat, giving us a nice ring of high magnetism around a low magnetism zone.
