ALUMNI NEWS Issue 28 February 2019 for Alumni and Friends EARTH SCIENCES Contents MESSAGE FROM THE CHAIR NEW FACULTY AND STAFF APPOINTMENTS MELISSA ANDERSON Melissa Anderson is an economic geologist who began her appointment as Assistant Professor in the Department in August, 2018, following the completion of her PhD at the University of Ottawa and the GEOMAR Helmholtz Centre for Ocean Research Kiel (Germany) under the supervision of Mark Hannington (PhD 1989). After growing up on the land-locked prairies, Melissa wanted a change of scenery and her attention turned towards deep-sea research. Her work focuses on understanding the relationships between tectonics, volcanism, and ore formation in subduction-zone settings in the western Pacific. In particular, she tests the hypothesis that subduction- related tectonic complexities, such as terrane collisions, asymmetrical hinge roll-back, or pre-existing structures, directly influence the location, size, and composition of seafloor massive sulfide deposits. Given the scale of this problem, Melissa draws on a diverse set of field-based and systems will be an important focus of this work, with an analytical approaches, involving international seagoing emphasis on comparing the structural elements of world- research expeditions, innovative approaches to remote- class mineral districts with modern arc-backarc settings. predictive seafloor geological mapping, and integrated New research is also needed to better understand the origins petrology, trace element geochemistry, stable and radiogenic of giant ore deposits found on land for which there are no isotopes, and alteration studies. Her long-term research focus modern analogs; are large deposits waiting to be discovered will be on the transfer of modern seafloor research to the in unexplored settings of the modern oceans, or do geological development and enhancement of genetic and exploration processes operate in a fundamentally different way today? models on land.
