Petrography and Mineral Chemistry of Monte Epomeo Green Tuff, Ischia Island, South Italy: Constraints for Identification of the Y-7 Tephrostratigraphic Marker in Distal Sequences of the Central Mediterranean

Abstract: The 56 ka Monte Epomeo Green Tuff (MEGT) resulted from the largest volume explosive eruption from Ischia island (south Italy). Its tephra is one of the main stratigraphic markers of the central Mediterranean area. Despite its importance, a detailed characterisation of the petrography and mineral chemistry of MEGT is lacking. To fill this gap, we present detailed petrographic description and electron microprobe mineral chemistry data on samples collected on-land from the MEGT. Juvenile clasts include pumice, sc… Show more

“…The activity of Ischia is subdivided in five stages (i.e., >150-75 ka; 75-55 ka; 55-33 ka; 28-12 ka; 12 ka-1302 CE), characterised by different eruptive styles and types of products (e.g., Poli et al, 1987;Brown et al, 2008). The third stage of activity (55-33 ka) included several explosive events, following the largest 55 ka Monte Epomeo Green Tuff eruption (MEGT; Poli et al, 1987), recognized in the Mediterranean region as the Y-7 tephra marker horizon (e.g., Tomlinson et al, 2014), although this attribution has been recently questioned (D'Antonio et al, 2021).…”

“…Many studies have been carried out in the Bay of Naples regarding the marine tephra layers, providing information on the marine and volcanic hazards, both at Ischia [45][46][47][48][49][50] and on the Naples continental shelf [12,[51][52][53]. The reconstructed stratigraphic model provides improved estimates of future eruption hazards, such as plume height and the total volume of eruptive material.…”

“…(a): Pyroxene composition. Compositional fields of clinopyroxene from Vulture (data from[18][19][20][39][40][41]), Vesuvius (data selected from[37,42]), Ischia (data from[43]) and Campi Flegrei (data from[44][45][46][47][48][49][50][51][52][53]) are shown for comparison; (b) amphibole (after[38]). Data of amphiboles from Vulture (from[18,20,40]) and Vesuvius (from[42]) are also shown for comparison.…”
