Tephrostratigraphic and tephrochonological dataset of tephra layers from northern Chile

The dataset comprises the geochemical and chronological information of the tephra layers investigated in the paper presenting the TephATA database (Leicher et al., in review). TephATA (https://www.crc1211db.uni-koeln.de/tephata) is a database designed to store tephra sample metadata alongside respective analytical datasets, with a focus on the Atacama region in northern Chile. This dataset provides an overview of the samples and their ages, along with their glass geochemical compositions obtained by EPMA-WDS/SEM-EDS and LA-ICP-MS.
