If it happened all at once then all one needs to see is segregated flows etc.
Fine clay particles do not settle out of flows. You need still waters for this. Also, you need an entire warm season to produce just one layer of diatoms. Your flood model can not explain this.
Its unlikely these lakes , even, were from annual events.
We observe lakes producing them now. Not only is it likely, it is happening right now.
Just because annual events can make these layers is not evidence this is what happened in these deposits.
Yes, it is evidence. That's the whole point. We observe lakes producing alternating layers of diatoms and fine clay sediments right here and now. We observe hundreds of thousands of these layers in lakes, uninterrupted by any global flood. We observe that chaotic flows do not allow for the settling of fine clay and diatoms. I think the conclusion is very clear.
All one finds is layers laid by a layering process.
A chaotic flow structure could do this too.
No, they can't. Fine clay particles can not settle out of chaotic flowing waters. They flow with the water. That is why you have deltas in rivers that empty into the ocean. As the flowing waters stop they dump the fine clay sediments that were flowing with the water.
Also, you need to account for hundreds of thousands of years worth of diatom growth in a single flood year. That doesn't work either. Even worse, you need to explain the 14C dating of insect and leaf debris found in these layers. They are consistent with annual processes as well, as discussed here by our very own RAZD:

So there are three falsifications of a global flood here:
1. Fine sediments found in these layers can not be laid down by chaotic flowing waters.
2. Hundreds of thousands of years worth of diatom growth.
3. 14C dating of organic material is consistent with annual deposition.
In the great mega floods of recent Iceland they only lately discovered that PULSES of water could make layers of sediment in a quick single event.
Layers of what type of sediment? If it wasn't alternating layers of fine clay sediments and diatoms that sorted insect and leaf debris by tiny differences in 14C then you haven't addressed the evidence.
