Continental arcs are thought to be variably enriched in economically important sulfide mineral deposits, however our understanding of the conditions necessary for their genesis is still incomplete (Jenner, 2017; Cox et al., 2019). Chalcophiles are sulfur loving elements known to be closely linked to the behaviour of sulfides 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 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 is 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 continental arc volcanoes; Popocatépetl volcano and Colima volcano, Mexico, to provide constraints on chalcophile element.

大陆弧被认为在经济上重要的硫化物矿藏中具有不同的丰度，但我们对其形成的必要条件的了解仍然不完整(Jenner，2017；Cox等人，2019)。亲硫元素是已知与硫化物行为密切相关的亲硫元素，可以告诉我们许多关于在这些弧形火山下工作的地壳和地幔过程的信息(Noll等人，1996年；Jenner等人，2010年；Sillitoe，2010年；Jenner，2017；Cox等人，2019年)。到目前为止，亲脂行为仍然相对难以捉摸，因为很难用分析设备的分辨率测量其特征的低浓度(Kent，2008；Jenner和Arevalo，2016；Cox等人，2019年)。这意味着明显缺乏大陆弧内亲磷元素浓度的数据集(Cox等人，2019年)。最近分析技术的改进意味着这现在是可能的。该项目旨在对墨西哥波波卡特佩特火山和科利马火山这两座大陆弧形火山的火山物质进行岩石学研究，以限制亲硫元素。
