New Inferences on Magma Dynamics in Melilitite‐Carbonatite Volcanoes: The Case Study of Mt. Vulture (Southern Italy)

This study provides the first micro-thermometric data of fluid inclusions (FIs) in mafic loose (disaggregated) xenocrysts and ultramafic xenoliths explosive products melilitite-carbonatite Mt. Vulture volcano (southern Italy). Pure CO2 late stage FIs hosted rock-forming minerals wehrlite clinopyroxene were trapped at local crust-mantle boundary (32 km). In contrast, trapping pressures within olivine are from 3.2 to 4.5 kbar (8–13 Considering ongoing degassing mantle-derived rich gases, together with seismic evidences presence low amount melts depth, tectonic control past volcanic activity, our opens new perspective about hazardous nature “quiescent” volcanoes.
