No body said it took 4 million catastrophic events.
There are over 4 million layers (actually recent core samples have shown over 20 million).
So what is your process for laying down 4 million layers, alternating between finer and coarser, lighter and darker?
Again, Mount St. Helens produced 100 of the layers in one day. So it would not take nearly as many as you claim.
Sorry that is volcanic ash. We are talking about lake varves.
No, events such as these combined with a world wide flood would be enough to produce most of what we see. Again, no one says that they don’t happen yearly. Just that all that we see did not happen yearly.
Please explain the mechanism?
Once again it can be done by a self sorting mechanism explained here, and in a Nature article. Silt is still made up of small particles and will eventually settle out.
The key word is eventually.
Still waiting for a model.
