Is this an ancient undersea river? The Laurentian Channel and Canada's shallow water Atlantic Coast

[@mellissadalby1402]

I could be wrong, but another bit of supporting evidence for the possible Glacial origin of the Laurentian channel is that Sable Island is believed to be a terminal moraine of an ancisnt glacier. Good point about the depth of the English Channel. Say, that sand model is a really great way to demonstrate the fault stretching action.

[@TheGeoModels]

Yes, apparently there are several moraines scattered around there. I have to remind myself about how far out the ice margin projected here...product of being from southern Appalachia, I guess. There aren't many things a sand model can't fix!

[@TheGeoModels]

Yes, it's basically horst and graben, with everything linking into a basal detachment that is close to flat, which produces the rotation of the blocks. Pretty much anywhere with horsts and grabens has gotten a look for oil and gas. I'm going to do one about offshore oil and gas with more detail on the idea. Thanks so much for watching!

[@TheGeoModels]

Another extension/horst-graben type setting you don't hear about with oil and gas is the African Rift Valley. The big lakes are basically the very earliest stages of the continental breakup that will ultimately produce a rifted margin like eastern North America. Lake Tanganyika is 4,800 ft deep or so but has kilometers of sediment in the overall rift basin which are of exploration interest.

There are many submarine ancient river beds that begin on the continental shelf and extend out into the oceans. When you extend your field of study into galactic physics and the effects of same upon all the planets in our solar system as well as the Sun and the cascade of solar effects to the terrestrial effects you will find that geomagnetic shifts lend themselves in no small part to polar shifts. During these events the oceans leave their beds and generate massive flooding and also massive fluvial excavation of channels which later, after the transition period, normalize to what we see now. The clock cycle at our location in the galaxy is circa 12,000 years, and our 12,000 year cycle is currently ending, which is why we are seeing the magnetic polar excursion happening and the magnetosphere declining - both at ever accelerating rates. This cycle has been tracked back no less than 72,000 years. As things stand, we can expect the transition period to continue into the late 2030s to mid 2040s where it will peak in the solar nova event and pole shift. From there it will be some 150 years to return to full stability. Each of these events are accompanied with mass extinction events. Do your research and think outside the box and you will find all the evidence. If you don’t you will not find the pieces of the puzzle due to the compartmentalizations of the current orthodoxy and dogmatic education/indoctrination system.

[@mercer1995]

That is a likely explanation but we could also look at the geological and hydrological situation between 300-250million years ago in the Permian period. The Appalachian mountains extended through where the channel is before that and sea levels were much lower in comparison to the coastline today or even at the last glacial maximum. Modelled Maps I’ve seen depict a large water body at that location

[@darrellc.symonds9339]

Thank you. I’m interpreting the channel is of “glacial origin”, meaning the channel is caused by glacial melt.

[@TheGeoModels]

No, physically carved by an ice stream (or the base of the ice sheet). It does not have a downhill grade along its full length (deepest part is towards land from its mouth at the shelf edge), and the base of the channel would have been beneath the ice and also about 1,000 ft below sea level during ice maxima... possibly more due to subsidence of the crust under the mass of the ice. It looks like a water channel, and the ice was "flowing" with gravity, but it's a mechanical feature, like a moraine that would get pushed up and left behind, a drumlin, etc. The channel is also massively huge. It's hundreds of feet deep and about 65 miles wide. It's interesting to think about whether flowing water could produce that size of feature into Earth rocks at Earth's gravity. I'm not sure of the answer, but outwash channels I can think of that you can see today are notably smaller. Might be a cool video...

[@ArronCharman]

I knew the basics of continental shelves and how they crack apart then get filled with sediment, but I'd never really considered before why it might be "wider" in some places than others. Could this perhaps be indicative of those areas being the last to fully separate during the rifting, thereby extending further the "stretched" portion of continental crust? Just an idea that popped into my head.

it very much looks like the st. lawrence river flows through it, it looks like other run off from the various islands do too, you can see a very similar structure come put of the gulf of mexico wrap around florida travel north then turn out to the ocean, the larentine channel is just much wider, maybe its just been trenched out by ice run off, a sub glacial channel?, a lake between glaciers on the various sections of continent?, does the st lawrence river have well developed oceanic silt channels running through the laurentian channel? or have these been washed out from glacial run off Ganges-Brahmaputra and columbia river have very detailed deep sea channels, so maybe theres some topographic map that already shows the finer details of the ocean floor in the area

[@Clubberdude-sp1gw]

I think the North Sea bed is more like the morphology of a dry desert, in other words sandy with large (ish) dunes that run across it. Seen little evidence really of large rivers on the topographic maps (aside outflow channels from the Humber, Thames, Tyne etc). The average depth is indeed 200-300 ft (60-90 meters), but can get up to I think approaching a mile deep (5000ft; 1600 m) in a pretty narrow channel off the Norway shore, its likely this deep channel scoured by ice.

[@Dragrath1]

In terms of submarine channels it might we worth discussing submarine channel and fan structures created by turbidite flows from major rivers and or glacial outburst floods. The Cascadia coastline is a particularly mind boggling landscape as the sediment loads from the glaciers and glacially induced floods have created a crazy submarine depositional landscape including fully filling in the Cascadia trench with thick layers of sediment which based on the recent induced seismic surveying has already become lithified into a many kilometer thick (i.e. too thick to drill through to the bottom) sedimentary forearc wedge of sandstone and siltstone layers that extend some distance out beyond the trench onto the Juan de Fuca plate. From the colloquium guest speaker lecture on the results it plays a huge role in shaping the terrifying megathrust Earthquake potential out in the Cascadia subduction zone as the thick lithified sediments mean there is a much larger fault section with the right properties temperature pressure and rigid brittle crust to become fully locked due to friction. Oh and the debris fan and channel doesn't stick to the North American and Juan de Fuca plates but actually extends out across the Juan de Fuca ridge onto the Pacific plate because the fan system is absolutely enormous and full of suppuratives. It is IMO the most fascinating of the major submarine fan delta systems due to crossing 3 active tectonic boundaries but there are lots of other such examples some including impressive erosional canyons or building up to the point of breaching the surface as a true river delta in parts. As for the North American East coast continental shelf It should be noted that here in Virginia to the east of the Appalachians and to the west of the costal plain are two additional sets of block faults the Triassic basin graben split from the costal plain by the Piedmont horst. As a general guide the transition zone between the piedmont and costal plain regions is roughly where I 95 was constructed making it a good rule of thumb for which physio-geographical region you are within at least for the state of Virginia DC and Maryland, I don't know how well this extends outside of VA and the greater DC metropolitan area however. Now because of its relevance in understanding some of the fossils in the region related to the Ediacaran biota and Paleozoic in particular I am aware of some additional nuances in the greater Maritime Provinces Newfoundland area specifically that along with much of New England the rocks here are part of Avalonia which was a Neoproterozoic to Paleozoic microcontinent built up from a complex of mature largely tropical subduction archipelago complex. The rocks in that area are where the overlying tectonic plate the archipelago that was greater Avalonia resided on pulled in the Laurentian continental shelf and initiated slab failure ultimately obduction a piece of that overlying Iapetus(?) plate preserving a rare snapshot of Ediacaran abyssal plain fauna. Ultimately Avalonia and the other accreted terrains sandwiched between Laurentia Baltica and Gondwana would serve as the weak point where Pangaea ripped itself apart making the given continental shelf in the process. @TheGeoModels keep up the paint geological cross section profile skills and videos!

[@TheGeoModels]

[@ranmyaku4381]

How does the formation of the St Lawrence and maritime area with ice ages match with the formation of the tablelands (earth's mantle) in Gros Morne National Park, Newfoundland? Was the glacial carving after this occurred and did this shift or alter the area further? Would this be what formed the deep fjord like areas in the park as well?

[@boston_octopus_442]

Is there an equation that governs the width and slope of the faults? Or does it break and slump randomly?

[@TheGeoModels]

It's definitely not random, but in the real world, all sorts of mechanical heterogeneities in the rock mass would impact fault geometry and spacing. Generally speaking, the orientation of the stress field that causes the rock to fail and the "strength" of the rock (internal frictional characteristics) define how a given rock mass will fault. Density of the rock goes into this, as it determines elements of overburden stress. Folks can use variables like these to make numerical models that are really dang close to the real world, but the finer details in a real-life, varied rock mass will always cause some departure from purely math-based prediction.

[@TheGeoModels]

So yes, you can do some pretty good work with math alone if you have some sense of the rock's frictional strength, density, and the geometry of the zone that is going to get stretched/squeezed until it fails. I ought to do a video with a "sandbox model" (lots of older ones on my channel) that shows the level of regularity you can get from consistent materials.
