资源简介：
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.
Most of this information is contained in a series of spreadsheets that follow tephra community recommended best practices.
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. See DOI: 10.5281/zenodo.3866266 for more information.
