Isn't this the same formation that contains millions of fossil fish? If
so, and if the varves are annual deposits (meaning very slow
deposition), how do the OECs explain the fossilization of fish, which
float (due to gases produced by bacteria and trapped inside of their
bodies when they die)?

How did the fish get trapped on the bottom long enough to become
fossils?
