On the other hand, here is a Ne-21/Be-10 diagram from a very cool paper by Florian Kober and Vasily Alfimov: This figure has a lot of data in it that are beside the point from the perspective of this post, but the point is that it has the opposite axes: Be-10 concentration on the x-axis and Ne-21/Be-10 ratio on the y-axis. I think inverting the diagram so that burial goes up just confuses readers. Thus, I advocate always plotting the longer-lived nuclide of the pair on the x-axis, and the ratio of the shorter-lived to longer-lived nuclide on the y-axis. Of course, I am in the US, but I am not just cheering for my own team here.

Thus, exposure still goes to the right (at least for a while), but burial goes UP. Not what we expect from our previous experience with the Al-26/Be-10 diagram. At present, the choice of axes in two-nuclide diagrams involving Ne-21 in the literature appears to reflect your position in relation to the Atlantic Ocean. It really does make more sense for two-nuclide diagrams to always behave the same way no matter what nuclide pair is involved.

From his research, our evolutionary geologist may have discovered that other geologists believe that Sedimentary Rocks A are 200 million years old and Sedimentary Rocks B are 30 million years old.

Thus, he already ‘knows’ that the igneous dyke must be younger than 200 million years and older than 30 million years.

The field relationships are generally broad, and a wide range of ‘dates’ can be interpreted as the time when the lava solidified.

What would our geologist have thought if the date from the lab had been greater than 200 million years, say 350.5 ± 4.3 million years?

I’ve done it this way in the version 3 online exposure age calculator, which will generate two-nuclide diagrams for all combinations of Ne-21, Be-10, Al-26, and C-14 in quartz, and also in the ICE-D database which makes use of the v3 calculator as a back end.

Summary: Draw two-nuclide diagrams so that burial always goes the same way. In the same way, by identifying fossils, he may have related Sedimentary Rocks B with some other rocks.Creationists would generally agree with the above methods and use them in their geological work.From the mapped field relationships, it is a simple matter to work out a geological cross-section and the relative timing of the geologic events.His geological cross-section may look something like Figure 2.(Creationists do not agree with these ages of millions of years because of the assumptions they are based on.) Because of his interest in the volcanic dyke, he collects a sample, being careful to select rock that looks fresh and unaltered.


  1. Got a crush on Mitt Romney, or maybe one of his sons? It seems that America is going through a bit of a Mormon moment, with Mitt Romney's presidential campaign and "The Book of Mormon" bringing attention to the Latter-Day Saints in popular culture.

  3. It can be easy to feel overwhelmed by all of the dating app possibilities, or by the prospect of dating in general, but if the blizzard that the East Coast just got hit with is any indication, people are out en masse in search of connection, and that is only more true as the temperatures drop.
