Glass geochemical composition of tephra layers of the interval 253-313 ka from the Fucino F4-F5 record and proximal equivalents

The dataset comprises results of EPMA-WDS analyses of volcanic glass fragements of tephra layers identified in the Fucino F4-F5 sediment succession (central Italy) in the interval 253-313 ka. In addition, EPMA-WDS analysis of glass fragements from proximal outcrops from the Tufo Giallo di Sacrofano deposit from the Sabatini complex are provided.
