Abstract
|
Continental arcs are thought to be variably enriched in economically important sulphide mineral deposits, however our understanding of the conditions necessary for their genesis is still incomplete (Jenner, 2017; Cox et al., 2019). Chalcophiles are sulphur loving elements known to be closely linked to the behaviour of sulphides and can tell us a lot about the crustal and mantle processes at work beneath these arc volcanoes (Noll et al., 1996; Jenner et al., 2010; Sillitoe, 2010; Jenner, 2017; Cox et al., 2019). Up until now, chalcophile behaviour has remained relatively elusive due to difficulty measuring their characteristically low concentrations with the resolution of analytical equipment (Kent, 2008; Jenner and Arevalo, 2016; Cox et al., 2019). This means that there are a distinct lack of datasets for the concentration of chalcophile elements within continental arcs (Cox et al., 2019). Recent improvement of analytical techniques means that this is now possible. This project aims to conduct petrological studies on volcanic material from two different continental arc systems; Popocatépetl volcano, Mexico, and Santorini Volcano, Greece, to provide constraints on chalcophile element behaviour. It will also investigate the relationship between the concentration of sulphide found within erupted volcanic rock and the quantity of sulphur degassed during different eruptive episodes. |
