IOCG-IOA ore systems and their magmatic-hydrothermal continuum : A family reunion? – SY03

This symposium aims at highlighting our current understanding of IOCG-IOA deposits. It also aims at providing an opportunity to discuss major knowledge gaps and controversial ideas on the footprints, genesis and potential linkages amongst iron oxide-apatite and IOCG deposits, their variants, and certain skarns, porphyry deposits, albitite-hosted uranium or gold and other deposits associated with iron oxide and alkali alteration. Topics such as the critical conditions for ore genesis and linkages between IOCG and other deposits that are associated to IOCG in time and space will be put forward. Addressing these broad topics will provide a solid overview of these systems and trigger discussion on metal and fluid sources, transport and deposition mechanisms, and on the role and effects of deformation, metamorphism and metasomatism. The challenge is to provide a foundation for future breakthroughs and discoveries that will contribute to improve our understanding of these systems at various scales, and therefore help to solve some key questions that surround this enigmatic class of deposits, including those located in high-grade metamorphic terrains. Another objective of this symposium is to demonstrate how this knowledge can be used in exploration.

Keynote speakers include :
Dr. Kathy Ehrig (BHP Billiton – The Olympic Dam deposit)
Prof. Xin-Fu Zhao (China University – IOCG-IOA models from China)
Dr. Fernando Tornos (Consejo Superior de Investigaciones Cientificas – Magnetite-apatite systems from bottom to top)
Prof. Adam Simon (University of Michigan – The magmatic floatation model)

Types of presentation: Talks (up to 16) and Posters
