meteor hit during the Flood and the timing was such that the iridium was carried on that particular layer which was dispersed throughout the world as all the sedimentary layers were being laid down during that event.
If the meteor/asteroid with the iridium hit during the flood, the iridium would be mixed into many layers not just the one distinct layer.
You have NO idea whatsoever even what a fountain of the deep was!
So what was a fountain of the deep? What is the evidence of one? Where in the world is an example? Why is the convential geology wrong for that site?
I am thinking that a fountain of the deep would be a fissure of some depth (kilometers scale). A debris field radiating out with progressively finer material with distance. Fractures and sunken areas where vast amounts of water were removed.
What kind of geologic formation would hold and release the water of the Flood?
Creation scientists have had a century or more to answer thses questions. Please educate us.
