As far as I know. Nobody can point to what happened to the missing material. It just doesn’t exist in sufficient quantities anywhere to account for erosion as being the main cause. 🤷
Update.
I was looking for something else and came across this news that was just released a couple of days ago.
The Grand Canyon lacks a billion years of geological history
https://eminetra.com/the-grand-canyo...istory/710917/
Billion years of rock missing.
No definitive answers.
More conjecture leading to more questions.
In all honesty, to say we know how the Grand Canyon was formed at this point is fraught with folly.
There is nothing else on Earth 🌎 like it to compare to.
Well...
Unless, it’s under the sea..
At this point in time however, it’s a true Enigma...

1) Earth is 4.6-billion years old.
2) The oldest rock exposed at the bottom of the Grand Canyon is 4.0-billion years old, Vishnu Schist, which is 10,000-feet thick.
3) So 0.6- billion years is 'unaccounted' for to lay people.
4) Digging below the water line of the Colorado River will expose 'older' rock, down to the base of the crust, at 420-miles depth.
5) Missing material will be found in the in the paleoinventory of:
* glacial milk
* glacial till
* glacial tillite
* glacial till sheets
* Moraines
* Alluvial plains
* Outwash gravels
* Breccias
* Dissolved limestone
* In all locals 'downstream' over the last 300-million years
