Cosmogenic nuclide burial dating


Data from karst deposits serve as reference and comparison site for Alpine chronology as well as for cave genesis and palaeogeographical reconstructions, similar to that of the Siebenhengste massif in Switzerland.

Cosmogenic nuclide burial dating

Here is an example of a Be-10/Ne-21 two-nuclide diagram from one of my papers: Here I have put Ne-21 (the longer-lived nuclide) on the x-axis and the Be-10/Ne-21 ratio on the y-axis. I think no matter what the nuclides involved, you should always do it the same way as is commonly done for Al-26/Be-10 diagrams, so that burial goes down.

So, again, exposure goes to the right and burial goes down. Although I have not made a systematic historiographic study of this phenomenon, I believe that the European style is largely just due to the fact that the “Cosmo Calc” software put together by Pieter Vermeesch does it this way. Nearly all the two-nuclide diagrams in the existing literature involve the normal implementation of the Al-26/Be-10 diagram, so anyone familiar with this literature expects exposure to go to the right on a tw0-nuclide diagram, and burial to go down.

Les résultats obtenus sur deux échantillons d’un même étage mais spatialement distants donnent des âges d’enfouissement pliocènes (4,3 Ma et 3,4 Ma) conformes aux hypothèses génétiques préalables.

L’âge de ces niveaux de galeries établis post-plissement est donc assurément néogène.

Here’s an example: The lines are contours of burial time in Myr. This is the foundation of the method of cosmogenic-nuclide burial dating.
