Geochemical Atlas of Europe

GTK had a central role in the multimedia mapping program for the Geochemical Atlas of Europe, which represents the first published contribution to the IUGS Global Geochemical Baselines Programme. The atlas – which is accessible on-line – presents compilations of baseline geochemistry for soils, sediments and surface waters, covering 26 European countries. Survey results are used in formulating European environmental legislation and the databases forms a Europe-wide reference network for use in leveling national datasets.

Geochemical Landscapes of Alaska – New Map Presentations and Interpretations for 23 Elements in Surficial Materials

In cooperation with a GTK author specialized in statistical mathematics and data presentation, US Geological Survey (USGS) recently completed a new type of geochemical atlas of Alaska. Geochemical patterns are presented and interpreted for 23 elements, ash yield, and pH in soils and other unconsolidated materials from 265 collection sites throughout Alaska. This compilation is useful in assessing geochemical baselines and in interpretation of geochemical landscapes when the purpose is to identify broad regional patterns associated with geology, mineral resource provinces, and geochemical areas of interest in human, animal, and plant health issues.
