Summary

A rich legacy of geochemical data produced since the early 1960s covers the great expanse of Alaska; careful treatment of such data may provide significant and revealing geochemical maps that may be used for landscape geochemistry, mineral resource exploration, and geoenvironmental investigations over large areas. To maximize the spatial density and extent of data coverage for statewide mapping of element distributions, we compiled and integrated analyses of more than 175,000 sediment and soil samples from three major, separate sources: the U.S. Geological Survey, the National Uranium Resource Evaluation program, and the Alaska Division of Geological & Geophysical Surveys geochemical databases. Various types of heterogeneity and deficiencies [...]

Purpose

Geochemical data provide fundamental constraints on geological, biological, and environmental processes. Geochemical data reveal local enrichments that relate to rock types or point to mineral deposits, and may indicate areas of environmental concern. Geochemical data also show local depletions that may be important for human and wildlife health. These data show the distribution of elements in sediments throughout Alaska. The data can be used for mineral exploration, environmental geochemistry, geologic mapping, and land use planning. > > Description_of_Geographic_Extent: State of Alaska >
