  <dc:description>&lt;p&gt;&lt;span&gt;Cosmogenic&amp;nbsp;&lt;/span&gt;&lt;sup&gt;26&lt;/sup&gt;&lt;span&gt;Al/&lt;/span&gt;&lt;sup&gt;10&lt;/sup&gt;&lt;span&gt;Be isochron burial dating is a powerful tool for dating sediment burial over the past several million years. By measuring in-situ&amp;nbsp;&lt;/span&gt;&lt;sup&gt;26&lt;/sup&gt;&lt;span&gt;Al and&amp;nbsp;&lt;/span&gt;&lt;sup&gt;10&lt;/sup&gt;&lt;span&gt;Be 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 calculate paleo-erosion rates. While this approach has been used to date materials around the world for over a decade, few published codes exist for performing&amp;nbsp;&lt;/span&gt;&lt;sup&gt;26&lt;/sup&gt;&lt;span&gt;Al/&lt;/span&gt;&lt;sup&gt;10&lt;/sup&gt;&lt;span&gt;Be isochron calculations. The isochron calculation options that are available typically rely on numerous files and libraries, rendering modification and troubleshooting difficult. Moreover, the widespread use of proprietary programming languages – and their associated addon packages – can place an additional financial burden on an already costly endeavor.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;Pysochron (&lt;a class="anchor anchor-primary" rel="noopener" href="https://code.usgs.gov/recon/pysochron" target="_blank" data-mce-href="https://code.usgs.gov/recon/pysochron"&gt;&lt;span class="anchor-text-container"&gt;&lt;span class="anchor-text"&gt;https://code.usgs.gov/recon/pysochron&lt;/span&gt;&lt;/span&gt;&lt;/a&gt;) provides a solution to these issues. In its base form, it exists as a single script that can be easily modified, upgraded, and shared. Because it was developed in an open-source environment, all required computational packages are available free of charge. A user-friendly interface allows rapid modification of calculation parameters, and an automated commentary on isochron results provides insights and recommendations. Pysochron has been validated with 40 published cosmogenic&amp;nbsp;&lt;sup&gt;26&lt;/sup&gt;Al/&lt;sup&gt;10&lt;/sup&gt;Be burial isochrons around the world, with burial ages ranging from ∼5&amp;nbsp;Ma to ∼180 ka. As such, it is a promising option for members of the cosmogenic nuclide community seeking a straightforward, cost-effective, and flexible solution to isochron burial dating challenges.&lt;/span&gt;&lt;/p&gt;</dc:description>
