__STRATA FORMATION
7. The geologic column is said to be the complete sedimentary rock record, from the basement granite rock to the most recent strata at the top.
7a. The complete geologic column is said to exist in 24 large basins worldwide on the continents.
7b. Basins are theorized to have formed from large meteor impacts. The deepest basin is possibly at the Caspian Sea, which is over 20 km deep, filled with sedimentary rock strata. Other basins are also fairly deep.
8. Sedimentary rock strata cover about 75% of the continents, I think, and average about a mile thick. Some limestone, such as along the Gulf of Mexico, is 7 km or so thick, like in many basins as well.
9. The geologic column consists of 6 megasequences, each of which appear to have been deposited by major flooding during "transgression" (rising water) and sometimes partially removed during "regression" (falling flood water). The Canadian shield and other locations appear to be where regression removed all of the sediment.
9a. The duration between megasequences appears to have been brief, because very little rain erosion appears to have occurred between their depositions.

__GLOBAL ROCK STRATA MEGASEQUENCES
_Creationists support megasequences in a modified geologic column. Would it be satisfactory to refer to it as the Flood Geologic Column? You can find megasequences in several articles at creation.com/search?q=megasequence
Here are some samples.

Can ‘megasequences’ help define biblical geologic history?

[This says Creationist geologists, Austin, Wise and Snelling first considered the idea of Sloss unconformity-bound sequences as Great Flood megasequences. Then here's a quote re Clarey et al, which is followed by discussion and conclusion, which is similar to your caution, I think. Ed.]
_p.29:
Young-earth creationist Clarey reported on the results of his analyses of transcontinental Sloss stratigraphic sequences, which he also defines as ‘megasequences’:
_“Using data from over 500 stratigraphic columns, I examined megasequences across North America to document the sedimentary evidence for the Flood’s catastrophe. At each site, the megasequence boundaries were identified, along with the thicknesses and extent of individual rock types.”51
_A new seventh megasequence was identified by Clarey at the Midcontinent Rift of North America:
_“Preliminary results demonstrate the presence of a seventh megasequence below the six common fossil-bearing megasequences. It lies just below the Sauk Megasequence in what secularists [i.e. naturalists] call the late Precambrian or Proterozoic Era. However, this newly delineated pre-Sauk sequence may be instrumental in documenting the onset of the Flood.
_“In part, the pre-Sauk megasequence was created by a tremendous outpouring of basaltic lava that split open central North America and caused the Midcontinent Rift.

... In conclusion, it is suggested that megasequences (and their bounding unconformities) can indicate globally-controlled tectonic (including volcanic), tidal, eustatic and hydraulic activity, which would have controlled sedimentation during the Flood. Unconformities are understood to be erosive boundaries created by the combination of tectonic movements, tidal effects, eustasy and hydraulic action. As explained earlier, unconformities do have time significance, as they mark the occurrence of an event in real time which interrupted the otherwise continuous deposition of sediments during the Flood. The determination of MSQs in a region gives the stratigraphic framework of the depositional history of the Genesis Flood for that region. From the correlation of MSQs, it may be possible to construct a Flood stratigraphic framework in which to interpret the depositional history of the Genesis Flood for the entire earth. As Table 10 shows, the example correlation done suggests that five of the inter-regional unconformities defined in each region are possibly world-wide in extent, indicating the possibility that five major tectonic/ eustatic (or other) events were globally-controlled. It is suggested that this concept be adopted for interpreting Flood geology for several reasons, including the fact that MSQs are defined by physical boundaries (unconformities), and are thus lithostratigraphic (as opposed to time stratigraphic [evolutionary]). Each sequence refers to a cluster of strata of varying but continuous (relative) age, that is, continuous deposition (within the sequence/depocentre). It is suggested that MSQs represent more coherent subdivisions of geologic time within a single tectonic domain during the Flood, and should be utilised to replace the presently used uniformitarian geologic time system for analysis of the depositional history of the Genesis Flood.
