"The favorable response to the reports on the geochemistry of unconsolidated surficial materials of the conterminous United States . . . led us, in 1975 to initiate a somewhat similar survey of Alaska. The principal objective of studies of this type is to establish estimates of the abundance of elements in soils and other surficial materials. Such information is useful in the evaluation of geochemical data for (1) mineral resources, (2) environmental appraisals, and (3) the definition of broad-scale geochemical patterns. For about six years this effort progressed slowly, on a non-funded, time-available basis. During fiscal years 1982 and 1983, however, some funds were made available through the USGS Energy Lands and Alaska Miner Surveys programs which allowed for the completion of the field work-phase of this project"--Page 1.
