This data compilation is a component of the State of Alaska's Strategic and Critical Minerals (SCM) Assessment project. For this report, DGGS digitally compiled sample and analyses documentation, geochemical assays, and location information for more than 22,500 historical samples that were originally collected to investigate occurrences of strategic and critical elements throughout Alaska. The objective is to update the State of Alaska's statewide digital geochemical database in order to more clearly identify areas with SCM potential.

Historical sample-collection and analytical procedures and vary considerably. Digital tables of geochemical-analytical data were compiled by DGGS for each sample, and where available, we included documentation of sample type and preparation methods, as well as the analytical method for each element. Great effort was made to interpret and correct obvious typographical errors in the original data, however, when no reasonable correction could be determined the original printed value was included in this digital data set. DGGS recommends that the reader of this report and the user of this data verify the location accuracy and the correctness of the analytical values represented in this report by using the original references. While DGGS has made every effort to ensure these data are clean, correct and error-free, the reader should understand that much of this information has been hand entered or digitized, and hand checked; processes that are never completely error-free. DGGS anticipates a few errors are present in this data and urges the user to check the accuracy of the information. We would appreciate learning of any errors encountered, so the source information can be continually upgraded.
Location coordinates for each sample were derived by DGGS staff by scanning station-location map figures from individual reports, georegistering the map figures in ArcGIS v. 10.2.2, creating a point layer of station locations, extracting latitude-longitude coordinates, and linking them to their associated sample number in the geochemical data tables. The precision of the digitized points does not correctly reflect the actual accuracy of the locations. We estimate that most of the listed coordinates plot within 1000 meters of the actual sample location. To determine the horizontal accuracy of a specific data point, users should evaluate the methodology and level of detail provided in the originating reports and maps.
