The Behaviour of Economically Important Elements During Crustal Processes in a Continental Arc Setting

大陆弧被认为富含经济上重要的硫化物矿床，但我们对其成因所需条件的理解仍然不完整（詹纳，2017年;考克斯等人，2019年）。亲硫元素是已知与硫化物的行为密切相关的亲硫元素，并且可以告诉我们很多关于在这些弧火山下工作的地壳和地幔过程的信息（Noll等人，1996;詹纳等人，2010; Sillitoe，2010;詹纳，2017;考克斯等人，2019年）。到目前为止，由于难以用分析设备的分辨率测量其特征性低浓度，亲硫试剂的行为仍然相对难以捉摸（肯特，2008;詹纳和阿雷瓦洛，2016;考克斯等人，2019年）。这意味着明显缺乏大陆弧内亲硫元素浓度的数据集（考克斯等人，2019年）。最近分析技术的改进意味着这现在是可能的。该项目旨在对两个大陆弧火山的火山物质进行岩石学研究; Popocatépetl火山和Colima火山，墨西哥，以提供亲铜元素的限制。

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.
