DOI: 10.1007/s12040-020-01429-6
Abstract: We report the widespread extent of Toba volcanic glass shards in the Central Indian Ocean Basin. Investigation of four sediment cores (7º–17ºS) revealed several shard-rich horizons (SRH) that provide the first detailed tephrochronology for volcanic… read more here.
