Gold- and PGM-Bearing Conglomerate of the Valdez Creek Mining District, Alaska.

摘要

The U.S. Bureau of Mines is conducting a four-year (1987-1990) study to assess the mineral resources and mineral development potential of the Valdez Creek Mining District in southcentral Alaska. This study is part of the Bureau's ongoing statewide mining district evaluation program. This report summarizes the Bureau's site specific evaluations of two areas (Tyone and Peters Creek) of the district that were investigated to determine the bedrock sources of gold and PGM in the alluvial gravel of both areas.
