Geodatabase for Marine Placer Platinum

The ultramafic rocks of the Red Mountain in Goodnews Bay area of southwest Alaska have been the commercial source of onshore placer Pt since 1926. The proximity of the Red Mountain to the Bering Sea, geophysical survey revealing the possibility of drowned ultramafic and paleo-drainage channels offshore, and the platinum samples collected by various agencies suggests the availability of a significant quantity of marine Pt accumulations in this region. I have created a comprehensive geodatabase for future Pt prospecting and possible exploration in the offshore regions of Goodnews Bay. The geodatabase has been hosted as an ArcIMS site for interested agencies to download the data
