ISGAM

Second International Symposium on Granites and Associated Mineralizations -- ISGAM II

 

 
Granite sensu lato is the scum of the earth, the light material that came to the surface to form the crust; it composes the continents on which we live and from which we extract important mineral wealth. A Second International Symposium on Granites and Associated Mineralizations was convened in Salvador, Bahia, Brazil, in August, 1997, to evaluate progress in our understanding of the evolution of the earth's crust, an evolution that involves processes of growth and differentiation through which important metallic elements, such as tin, copper and gold are concentrated into economic mineral deposits. In the ten years since the first ISGAM, we have realized significant developments in the analytical tools available to us in our studies of granites. At the grain scale, these developments have permitted us to collect chemical data with smaller and smaller spatial resolution at lower and lower levels of concentration. At the global scale, we have seen an explosive growth in data collected remotely by satellite-borne instruments. Indeed, the huge growth in data available at all scales has allowed us to advance significantly our understanding of the processes involved in crustal evolution. This Symposium was important, therefore, to evaluate our progress during the past decade and to identify important new research directions.

One hundred fifty participants from twenty-two countries attended the Symposium, including three faculty from the Department of Geology at the University of Maryland. Two of ten invited keynote talks were presented by Profs. Michael Brown (Laboratory for Crustal Petrology) and Philip A. Candela (Laboratory for Mineral Deposits Research), and Dr. Philip M. Piccoli (Laboratory for Mineral Deposits Research) presented one of twenty-five invited lectures. Furthermore, Prof. Brown presented an evaluation of the scientific importance of the Symposium in geology as part of the opening ceremonies.

 Studies of granites and associated mineralizations represent one of several areas of research excellence in the Department of Geology at the University of Maryland, and readers may recall it was only two years ago that the Third Hutton Symposium on the Origin of Granites and Related Rocks, sponsored by the Department of Geology, was held at the University. Further information on research by Brown, Candela and Piccoli is available at facilities.
