Service Description: Data layers from the Geologic map of Alaska including uranium lead geochronology, radiometric ages, contacts, faults, and geologic unit polygons.

This map and associated digital databases are the result of compilation and interpretation of published and unpublished 1:250,000-scale and limited 1:500,000- to 1:63,360-scale maps. Covering the entire state of Alaska, it reflects more than a century of work by a host of geologists and almost two decades of compilation work.
