Again, what makes all of you so sure sedimentary rock can not form quickly besides preconceived beliefs?
As the article debunking your unconformity noted, which I'm sure none of you actually read....

"The lower rocks are composed of grey vertical beds of alternating greywacke and shale.

11 Greywacke is a type of sandstone which indicates that it was deposited very rapidly. It is composed of particles with a range of sizes, from very coarse sand to fine clay. This means that the sediment was transported and deposited so rapidly that it did not have time to sort into different sizes (as occurs on beaches and in rivers today).
Also, the grains of sand in greywacke are not rounded, but jagged, indicating again that the sand was transported rapidly. If it had been transported slowly in a river, the sharp edges would have been worn smooth as the moving sand particles rubbed each other"
Also if it took millions of years to form, the grains would have been rubbed smooth by continued water action, being it requires a fast turbulent current capable of mixing the aggregates.
And there are not a single weathered aspect between layers.
It's not that creationists need explain how it got there, it's evolutionists that need to explain how it formed so rapidly with no signs of the weathering we see all around us in between the layers if it took the claimed amount of time to form each layer?
And no, please do not try the pitiful excuse that it was an ongoing process, because then the aggregates would have been worn smooth by the current creating the turbulence.
The only thing we can not observe in the unconformity or any other geological sedimentary layer is geological time......
