Alaska Mineral Resources
The Alaska Resource Data File project to update the USGS database of mines, prospects, and mineral occurrences in Alaska began in 1996. That year, USGS Open File Reports (OFRs) were published for six 1:250,000-scale quadrangles: Adak, Demarcation Point, Holy Cross, Mount Michelson, Unalaska, and Umiat. An additional OFR presented an explanation of the data fields used in the database. Since that time, OFRs have been published for an additional 114 quadrangles. No reports have been generated for the 33 quadrangles that do not contain any known mineral occurrences within their boundaries.
The Alaska Resource Data File website presents multiple ways to access the 120 reports and data. Quadrangles can be selected from either a map or a table. The Open File Reports for each quadrangle are downloadable as Adobe Acrobat PDF files. Digital versions of the data and report bibliographies are also available for download. Users may also access the data via the Mineral Resources On-Line Spatial Data website, where a Google Earth presentation is accessible.
The initial compilation of the dataset is complete; continued updating of records is ongoing with periodic releases planned.
