The Gulf of Mexico is Not a Sea

And it wasn't eroded away, so it was and still IS part of the geological column.There is net deposition in the Gulf.The geological column is not over and done with.Time to dodge again?Like you have dodged the issue of Green River Formation -- Varves, Fossils, Time and Geological Columns

It formed in the Eocene period and is part of the geological column for that age in that area. It is adjacent to The Grand Canyon (the Green River is tributary to the Colorado River).

​

Yet this formation is curiously absent from the Grand Canyon stratigraphy ... how do you explain this absence when chronologically it was laid down during the formation of the Grand Canyon stratigraphy?

​

How do you explain the very thin varve layers, "mean thickness of a varve here is 0.18 mm," of alternating light and dark layers of very fine sediment (and we have talked about how long it takes to deposit very fine material from suspension in water)? There are over 6 million pairs of alternating light and dark layers ...

​

How do you explain the different rock types that are part of the formation ... and particularly the layers of volcanic ash within/between the varve layers?

​

How do you explain the layers of evaporite minerals within the varve layers?

​

Note the correspondence of layer times with radiometric dates. How do you explain this?

​

Note that the areas of deposition shifted over the time period of deposition in a way that corresponds with astrochronological dates. How do you explain this?

​

This all left a "continuous record of six million years" of evolution in this area ... how did the fossils get sorted by radiometric age? How did the radiometric isotopes get sorted with depth in the formation?

​

The overall deposition was so gentle (" ... The limestone matrix is so fine-grained that fossils include rare soft parts of complete insects and fallen leaves in spectacular detail ...") that these fossils were not torn up. How does this mesh with your model for the formation of the "geological column/time scale" in this area?
