Mapping the geochemistry of the Earth’s surface at global to local scales (3rd Arthur Darnley Symposium)
Understanding the current abundance and spatial distribution of chemical elements in different compartments (e.g., soils, sediments, surface and ground water) of the Earth’s near-surface environment is essential if we are to be able to recognize and quantify natural or human-induced chemical changes to these compartments in the future. Continental-scale geochemical mapping programs have recently been completed in Europe, Australia, China, India, USA, and Mexico. Other countries have initiated national-scale geochemical mapping programs. This session, organized by the International Union of Geological Sciences/International Association of Geochemistry Task Group on Global Geochemical Baselines, will provide the opportunity for geoscientists from these broad-scale geochemical mapping projects to come together to present results from these studies and to discuss future research needs and opportunities in this field. Although the primary focus of the session is on national- and continental-scale geochemical mapping, we also welcome contributions from studies conducted at a more local or regional scale.
