The title mentions that Earth is missing that much geologic history, however it only mentions the Grand Canyon and says it's ubiquitous without further examples. Further research points to lots of articles with the same title but which cite the Ozark Plateu and Grand Canyon as examples.
It seems like the phenomenon is called The Great Unconformity, but nowhere are explicit examples of other places in the world mentioned. I even glossed the abstracts of several papers, and it is always the US that is the only example give. See? This is why geology is not a real science (https://www.youtube.com/watch?v=N9WGKbEWC9Q [youtube.com]).
You're blaming geology with your poor literature search skills.
I grew up (geologically) on another example of this "Great Unconformity" phenomenon in NW Scotland (except, our example has at least two unconformities representing up to 50km of erosion, then up to about 8km of deposition, then between 10, 5 and 3 km of further erosion (resulting in thickness variations of several km, over a few km on the ground) and then the Cambrian came in.
Since then, I've worked dr
