Short summary
Here we present the foundation dataset for TephraNZ, a formal, comprehensive, open-access reference dataset of glass-shard compositions for New Zealand tephras. We geochemically characterise 45 eruptive episodes ranging from Kaharoa (ca. 636 cal yr BP) to the Hikuroa Pumice member (ca. 2.0 Ma) from six or more caldera sources, most from the central Taupō Volcanic Zone.
