Research Interests
My research group focuses on (metamorphosed) hydrothermal mineral deposits that were formed from relatively hot, metal-bearing fluids circulating through Earth’s crust. We focus in particular on precious metals gold and silver and various critical metals (e.g., Bi, Co, Sb, Se, Te, V) since they play an essential role in various green, medical and communication technologies and have an increasing global demand in our ever-changing society. Our goal is to understand the transport conditions, deposition mechanisms, ore and alteration assemblage, and source region of the investigated metals for different hydrothermal deposit types (e.g., VMS, epithermal, orogenic gold). We also investigate the role of metamorphism on metal enrichment in hydrothermal mineral deposits, since many mineral deposits are metamorphosed. We use a multi-faceted approach that includes field methods (e.g., core logging, mapping), microscopy and micro-analytical tools to better understand ore-forming processes and the role of metamorphism. I closely work with industry partners, other academic units nationally and internationally, and the government (e.g., Geological Survey).
