June Lake Tephra Dataset

<p>This dataset describes a sequence of tephra layers recovered from a Holocene sediment core taken at June Lake, California, USA. It includes tephra sediment stratigraphy, sample information, tephra layer thicknesses, tephra grain size data, volcanic glass geochemistry, Fe-Ti oxide geochemistry, SEM imagery, and method information. The tephra layers originate from the Mono-Inyo volcanic system.</p> <p>Most of this information is contained in a series of spreadsheets that follow <a href="https://zenodo.org/record/4075613#.X5mcdi9h1aU">tephra community recommended best practices</a>.&nbsp;</p> <p>The listed files below follow the naming convention and format of Abbott et al. (2020) version 2.0, and they serve as worked examples of that format.
