Description

Fluid and melt inclusions can reveal key chemical and physical snapshots of ore-forming systems that may be obscured or overprinted by cumulative geochemical processes throughout geological time, rendering other data types (e.g., lithogeochemistry) problematic in routine exploration. The data obtained from inclusions may help to explain the distribution of ore minerals and grade zonation, as well as delineate ore fluid paleopressure and temperature, fluid and magma sources, and the state of sulfide and volatile saturation.

This full day workshop will enable participants to gain an understanding of the practical aspects of fluid and melt inclusion studies applied to ore-forming systems. Topics will include: (i) evaluating the value of engaging in inclusion studies to solve an ore system problem; (ii) guidelines for sample preparation and characterization, and the importance of robust petrographic observations in evaluating the timing of inclusion entrapment and preservation; (iii) an introduction to fluid and melt inclusion microthermometry and the application of software in modelling fluid and melt composition; (iv) analytical methods complementary to microthermometry that provide constraints on the volatile chemistry (e.g., Raman spectroscopy), and major and trace element (e.g., ore metals, halogens, sulfur) composition (e.g., microbeam methods, laser ablation ICP-MS, SIMS); and (v) case studies demonstrating the value in inclusion studies within ore systems on the African continent and beyond.

Participants will have the opportunity to examine fluid and melt inclusions from a variety of world-class ore-systems through petrographic microscopy.

Lunch will be provided, and all attendees will receive certificates of participation.

About the Presenters

Jacob Hanley

Department of Geology, Saint Mary's University

Jacob is a full professor and director of the Mineral Exploration and Ore Fluids Laboratory in the Department of Geology, Saint Mary's University in Nova Scotia, Canada. His group's research focuses on characterizing the sources, composition and evolution of fluids and magmas in ore-forming systems. He received the Mineralogical Association of Canada Young Scientist Award in 2016, William Harvey Gross Medal from the Mineral Deposits Division of the Geological Association of Canada (GAC) in 2011, and was the GAC Howard Street Robinson Lecturer in 2013. His group has led numerous studies involving the application of fluid and melt inclusions in evaluating ore systems including mafic-ultramafic Ni-Cu-PGE, porphyry Cu-Au-PGE, polymetallic "five-element" deposits, and orogenic gold.

Tobias Fusswinkel

Institute of Applied Mineralogy and Economic Geology, RWTH Aachen University

Tobias is a lecturer and laboratory manager of the Geofluids Laboratory LA-ICP-MS facility at RWTH Aachen University, Germany. His research is focused on the application of fluid and melt inclusion studies in the identification of fluid provenance and characterization of the compositional evolution of fluids in ore systems. He specializes in in-situ LA-ICP-MS fluid inclusion microanalysis and has developed new analytical protocols for Cl-Br-I halogen analysis of individual fluid inclusions, providing a novel and powerful tool for fluid source reconstruction and characterization of fluid-fluid interaction processes. He has led multiple workshops and seminars on fluid inclusion studies in the scope of programs such as the Horizon Europe Marie Skłodowska-Curie Innovative Training Network 'FluidNET' and the German Research Foundation's Priority Programme 'Dynamics of Ore Metals Enrichment'.
