Fermor Meeting 2017: Factory Earth

25 - 27 September 2017
Add to my calendar
Event type:
Organised by:
The Geological Society, Burlington House
Event status:

It is more than 10-years since the last detailed look at the role that volcanic and magmatic processes play in the role of ore deposits formation. The topic is still current and ready for a wide-ranging reassessment.

This meeting addressed the fundamental controls on metal transport and deposition in magmatic systems and questions such as:

  • What role do sulfide melts play in metal transport?
  • What are the key components of fertile magmas and how can they be identified?
  • What role do volatiles and semi-metals play in transporting and depositing metals?
  • How are ore metals concentrated during magmatic differentiation and transferred to the hydrothermal environment?

Topics for Discussion

  • Volcanic and ore processes: timescales and catastrophes
  • Magmatic hydrothermal plumbing systems
  • Sulfides through the crust: melts, minerals and volatiles
  • Volatile compositions
  • Magmatic and hydrothermal systems from mantle to surface
