Pysochron 2
June 10, 2026
Pysochron 2 is an open source 26Al/10Be burial isochron calculator, available for download in both .exe and .py formats. Like the original Pysochron, it uses orthogonal distance regression to fit isochron lines to measured concentrations of 26Al and 10Be and accounts for uncertainty using a Monte Carlo framework. The final output is a .pdf that contains the burial isochron diagram along with a comprehensive table of settings, constants, and modeled results.

Cosmogenic 26Al/10Be isochron burial dating is a powerful tool for dating sediment burial over the past several million years. By measuring in-situ 26Al and 10Be in a suite of samples from the same depth in a buried deposit, it is possible to quantify the inventory of cosmogenic nuclides produced after burial, date the burial of shallow sediments, identify sediment reworking, and...
