Among the items reviewed was the life of Commissions which have now been defined at a maximum of 8 years. As a consequence COGEOENVIRONMENT, which has been in existence since early 1990, was formally closed down at the IGC in Florence in August 2004. The decision by the IUGS Council to close COGEOENVIRONMENT did not in any way imply that the role of the IUGS in promoting geoscience in environment matters was completed.展开更多

I visited him on 17 November 2003 and on January 5th 2004 in his nice house in the outskirts of the city of Haarlem, the Netherlands. He was born in 1913 and, despite of his advanced age of 90 years now, he travels to Australia every yearto visit his daughter.展开更多

Most notably, he served as the lUGS Secretary General （1976-1980） at a pivotal time in its history, and as lUGS President （1984-1987）. The same boundless energy, enthusiasm, skill in communications, and ability to foster teamwork that characterized his work with the IUGS also carried him to preeminent scientific administrative positions in the Canadian Government, where he served as Director General of the Geological Survey of Canada and as Assistant Deputy Minister of Earth Sciences. His distinguished career was terminated in 1987 by his untimely death at the age of 52, following a painful struggle with cancer.展开更多

The samples proceed from the sites/regions corresponding to the Precambrian to Paleozoic/Postpaleozoic magmatism in the eastern and western Paraguay. The analysed elements were Si, A1, Na and K and thus the SiO2, AI/O3, Na2O and K2O content determined. The activation were performed in an annular 25Ci Am-Be neutron source with total flux of 5×10^7n.s^-1. The reactions used were （1） ^28Si （n, p） ^27A1, （2） ^27A1 （n, p） ^27Mg; （3） ^23Na （n, γ） ^24Na, the fourth element of interest, potassium, was analysed by XRF. The procedure overall uncertainties were checked as per the analysis of three compositae samples of SiO2： ＋ A12O3 ＋ NaHCO3 ＋ K2CO3 prepared as standards in convenient proportions. The determination of these parameters according to the last recommendations of the IUGS （International Union of Geosciences）, permits the classification of the rocks in the categories acid, intermediate, basic and ultrabasie, as well as the identification of the rock family and in certain cases, the norm and their magmatic provenance.展开更多
