Integrating isotopic microanalysis with other analytical techniques creates powerful new methodologies for understanding the evolution of rock samples at the sub-grain scale. Here we present Crystal Size Distribution (CSD) data for a 26,000 year old sample from Stromboli Volcano and accompanying isotopic microanalysis of the phenocrysts. A technique, called the ICSD plot, is introduced which given stated assumptions allows the integration of both sets of data to generate timelines of isotopic evolution through the volcanic system. The combined approach is powerful, allowing investigation of the magma supply, mixing, crystallisation and contamination processes prior to eruption of a volcanic sample. For Stromboli Volcano, the combined analysis suggests that the change in magma type following a cone collapse took roughly five years to complete, similar to the timescale of changes seen in recent decades.
