| Summary | (Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience
knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. The boundary between two distinct geological Zones in the Appalachians, Gander and Avalon, is straddled by a suite of
Devonian granites that are locally enriched in economically important elements (molybdenum, tungsten, tin, fluorine). There is a major fault, the Dover fault, at this boundary that may have influenced where and when the granites were emplaced in the
crust, as well as when and where those important elements are enriched. To test these relationships we have initiated a geochronology study to determine the ages of the granites, and the times at which the fault was active. We have employed the
U-Pb and K-Ar decay systems to date the geological processes. This poster presents our initial results. |
