Overview

Throughout the earth-science community, there is a high demand for geologic maps. Maps of this type help to inform the community on topics related to resource exploration, regional tectonics, geologic hazards, as well as provide a foundation for other studies. The last Alaska geologic map is more than 35 years old and is now out of date. Major new geologic mapping undertaken through the Alaska Mineral Resource Assessment Program (AMRAP) as well as new mapping by the State of Alaska and academics all contributed to the construction of the database from which the new map was produced.

The objective of this project was to produce a new digital geologic map for Alaska that enhanced, refined, and integrated all relevant information into one seamless database. The map and associated spatial and attribute data used to create this map have tremendous potential for contributing to solutions of regional environmental and natural-resource problems. It can be used to product many different maps for a variety of applications; the state map is just one application of the database. The database is continually being improved with new data being added and planned periodic updates including an interactive web version.
