EGS-AGU-EUG Joint Symposium

European Mineralogical Union EGS-AGU-EUG Joint symposium: Gold and Platinum Group Minerals: from Experimental Mineralogy and Microanalysis to Deposit Modelling
Nice, France, 7-11 April 2003

IMA-COM (Commission on Ore Mineralogy) and EMU (European Mineralogical Union) are organising a symposium session at the EGS-AGU-EUG Joint Assembly. The session (VGP3.17) is titled "Gold and Platinum Group Minerals: from experimental mineralogy and microanalysis to deposit Modelling". Convenors are Kari Kojonen (Finland) , Roland.K.W. Merkle (South Africa) and Nigel J. Kook (Norway).
The aim of this special session is to bring together researchers of experimental sulphide and platinum group element (PGE) mineralogy, ore mineralogists, exploration geologists, people responsible for the ore deposit modelling and evaluation and representatives from the mining industry who have an interest in gold, and platinum group elements. The session will comprise a series of presentations that will review and discuss the ore mineralogy, geochemistry and deposit modelling of existing deposits and exploration targets. The role of experimental sulphide and PGE-mineralogy is emphasized in interpreting the genetical conditions of ore deposit formation.

SMEC 2003

Study of Matter at Extreme Conditions 2nd meeting of the Study of Matter at Extreme Conditions
Miami, USA, 24 - 27 March 2003

The focus of the meeting will be to promote the integration of mineral-physics, high-pressure chemistry/physics and materials science. Following the tradition of the first meeting it will aim at science emphasizing the role of extreme variables (pressure, temperature and size) in materials science and geophysics.
