Join the Geoscience Society for their Webinar: Primary Gold Enrichment, Fluid Transport and Deposition in Different Geological Settings.
About this event
The Geoscience Society invite you to a presentation on Formation of Hydrothermal Gold Deposits: From Theory to Field Studies – Cosmo Howley (NT), Sigma–Lamaque (Canada), and Furtei (Sardinia).
Stephan Matthai will present the state-of-the-art of international research on the formation of mineralising hydrothermal fluids and their migration, alongside insights from numeric modelling on gold transport by hydrothermal fluids. He will explore the mechanisms of gold deposition in different geological environments and discuss how geological observations can be translated into conceptual and numerical models. Drawing on case studies from Australia, Canada, and Italy, he will illustrate how modelling can help evaluate competing genetic hypotheses and guide exploration strategies, with a focus on implications for mine-site exploration, particularly where field observations and data are abundant but the processes responsible for ore formation remain uncertain.
The genesis of gold deposits in Australia varies greatly. For instance, considering Victorian high-grade gold, the Fosterville story appears to differ significantly from the newly discovered Sunday Creek. Being able to create models that can explain the local variability, is of strategic interest.
Speaker Stephan Mattaei is based at the University of Melbourne and is the primary author of CSMP++, a code that permits the simulation of site-specific 4D ore deposit formation modelling, with links to several of the leading 3D geology modelling codes.

Stephan Matthai
Professor for Reservoir Engineering, Infrastructure Engineering, Melbourne University
Stephan Matthai is Professor and Chair of Reservoir Engineering at the University of Melbourne, Australia, and an internationally recognised expert on (multiphase) fluid-flow, deformation, thermal and chemical processes in the earth's crust. His research interests include coupled flow-, geomechanics-, and reactive transport processes facilitated by rock fractures and faults with applications to hydrocarbon extraction, gas storage / geological CO2 sequestration, enhanced geothermal systems, nuclear waste repository safety, and hydrothermal ore deposits. On these subjects, he has taught graduate students, consulted to industry, and acted as advisor to government agencies and professional societies.
In 1994, Matthai began the development of the object-oriented finite element – finite volume software known as the Complex Systems Modelling Platform (CSMP++, https://infrastructure.eng.unimelb.edu.au/matthai), now OpenCSMP (L-GPL). This toolkit has been the enabler of >200 peer-reviewed publications in leading international journals, including 2 articles in Science and others in Nature Geoscience. OpenCSMP is developed by an international team of developers from academia and industry and underpins applications like the ETHZ's Hydrothermal System Simulator (https://mineralsystems.ethz.ch/research/numerical-modelling.html), the CSMP Reservoir Simulator and the Australian Carbon Geo-Sequestration Simulator used in the international project GeoCquest (geocquest.org).
