国际勘查地球化学现状和发展趋势--第21届勘查地球化学国际会议介绍

21届勘查地球化学国际会议(IGES)于2003年8月29～9月3日在爱尔兰首都都柏林举行。共有来自27个国家200多名代表参加了会议，主要来自加拿大、澳大利亚、美国、爱尔兰(各40人左右)，中国只有作者一人参加，而原地球化学强国俄罗斯及前独联体国家无人入会。从提交论文数和大会发言看，勘查地球化学研究相对活跃的国家主要是澳大利亚和加拿大。

EXPLORATION GEOCHEMISTRY UPDATES AND POSSLBLE TRENDS FROM THE 21TH LNTERNATIONAL GEOCHEMICAL EXPLORATION SYMPOSIUM

The 21th International Geochemical Exploration Symposium (21th IGES) was held in Dublin, Ireland during August 28～September 3, 2003. Over 200 delegates from 27 nations attended the meeting. Fifty eight papers were orally presented and fifty papers were posted at the meeting. In addition to the scientific program, the Annual General Meeting of the AEG (Association of Exploration Geochemits) passed a resolution for the name change from AEG to AAG (Association of Applied Geochemits). Conventional geochemical exploration techniques such as soil and stream sediment surveys have been playing an important role in mineral exploration, while lithogeochemistry and hydrogeochemistry are still lasting interests for geochemists. A great attention has being paid to the study of deep penetrating techniques and its formation mechanism in overburden, which represents the future of exploration geochemistry, in the world recently; indicator minerals, isotopes and biogeochemical methods were studied for particular mineral deposits in the special landscapes, Canada and Australia. ICP/MS has been conventional procedures for the analysis of elements and isotopes in geochemical samples. Although the number of papers on environmental geochemistry was increased, most of them were related to the environmental geochemistry of mines or mineral deposits.
