Cosmogenic nuclides, such as ¹⁰Be, are rare isotopes produced in rocks when exposed at Earth's surface and are valuable for understanding surface processes and landscape evolution. However, ¹⁰Be is usually measured in quartz minerals. Here we present advances in efficiently extracting and measuring ¹⁰Be in the pyroxene mineral. These measurements expand the use of ¹⁰Be as a dating tool for new rock types and provide opportunities to understand landscape processes in areas that lack quartz.
