The Nordic Counties' Goldschmidt Conference Victor M. Goldschmidt spent most of his professional life as a professor in Oslo, so it was fitting that a Goldschmidt Conference be sponsored by the Nordic Countries. As the son of a chemist, it must have seemed natural to Goldschmidt to apply the principals of thermodynamics to his observations of minerals and their reactivity, but that work laid the foundation for a new approach in geosciences. His research, much of it based on the mineral assemblages he saw in the Oslo region, provided the groundwork for more quantitative study of chemical and mineralogical relationships. From it, our current exploration of natural systems and our drive to describe nature with models continue to grow. The study of the relationships between solids, liquids and gases, and their use in unravelling the secrets of the Earth and the Universe, continue to engage Nordic geoscientists, in topics as diverse as the Nordic landscape is itself. Iceland, Norway, Denmark, Sweden and Finland are each unique in their geological setting and each land has its own distinct culture, but the similarities between the Nordic countries are greater than their differences. Linked by common ancestors and the sea, the people of the North have followed a common, if sometimes not entirely cooperative, path since the retreat of the glaciers 10,000 years ago. Vast and unspoiled natural areas provide solitude or adventure and the cities offer culture and a window on history. The dark time of winter, which encourages small cosy gatherings of family or friends, cycles with the summer light, openness and freedom. The long evenings and 'white nights' pour back the life that the dark consumes. The north, in summer, is delightful, so we chose that time to welcome you to enjoy it with us. We chose Copenhagen as the site, because it has facilities to host a group as large as the Goldschmidt Conferences now attract. Furthermore, as the southernmost capital of the Nordic countries, it is closest to Europe and is often seen as the door between the North and Europe. Copenhagen is known as 'The City of Towers' and is famous for its many parks and gardens, including The King's Garden (front cover) and Tivoli. Small streets, half-timbered houses and canals near the harbour add to the charm. The conference is to be held at the University of Copenhagen, which for over 500 years has occupied buildings in the center of the city. Our activities will be based at the Geocenter, in a relatively new building on Øster Voldgade, which is the street constructed where the eastern city wall used to be. Some of the sessions will be held in H.C. Ørsted Institute, the home of chemistry,

mathematics and physics, and is named after the physicist who discovered electromagnetism. Geochemistry is currently one of the most dynamic of the geosciences. It is interdisciplinary, borrowing skills and approaches from many other fields and enfolding scientists from physics, chemistry, biology, engineering, materials science and medicine, to name a few. The sub-disciplines of geochemistry require measurement scales that span from nanometers to light years. Geochemistry seeks to define processes that range from the atomic to the cosmic. It attempts to explain events from the dawn of time, the rise of life, and today. It aims to discover the reasons for mass extinctions, climate change and mountain building and seeks to find oil, mineral wealth and clean water. The Goldschmidt Conference series was conceived to unite geochemists, so they could present their newest results, and to provide a forum for discussion and expansion of scientific networks. This 14th meeting will also seek to celebrate geochemistry, to share our enthusiasm for our field with each other and to make our science more visible to the public. The Plenary Day will present a number of general lectures which aim to summarise the state-of-the-art across a spectrum of geochemical topics and to highlight some of the provocative issues where geochemists play a leading role. Aside from the geochemical community, the public and the press will be welcome. Fifteen hundred abstracts were submitted and will be presented in about one thousand oral presentations and five hundred posters. Forty-eight symposia, organised in ten parallel sessions, will run over five days. Poster sessions and exhibitions will play a prominent role in the daily program. Pre-conference workshops will focus on specialised topics and pre- and post-conference fieldtrips were planned for each of the Nordic countries. In these pages, you will find the heart of Goldschmidt 2004, Copenhagen. For those of you who were with us, we hope these pages will remind you of the experience. For those of you who were not, we hope that you will catch a glimpse of the spirit of the meeting and enjoy the science that was presented there. On behalf of the entire Organising Committee for the Nordic Countries' Goldschmidt Conference, Susan L. Svane Stipp Geological Institute, University of Copenhagen.
