“Some of the areas that showed high potential were already known, but many of these areas had not previously been recognized. Areas identified by this method that have high resource potential based on limited data indicate both understudied and underexplored areas that are important targets for future data collection. A collaboration of the USGS and the Alaska Division of Geological and Geophysical Surveys, uses a new geospatial tool that can analyze publicly available mineral records. Earth elements in alkaline granitic rocks, gold and other commodity metals found in placer deposits.
- A new look at Alaska’s geology has produced an up-to-date inventory of known and potential mineral deposits around the state.
- The inventory, in a new study issued by the U.S. Geological Survey, identifies areas likely to hold minerals ranging from gold — the glittering metal that famously drew thousands of fortune-seekers in early territorial days — to obscure rare-earth elements that are used in ultramodern, high-technology devices.
- The result, expected to help guide future policies, provides a new perspective on areas that might have been overlooked in the past, the study’s lead author said.
