Geology

Monazite is a least four times more abundant than xenotime, except on upper No Name Creek where this ratio is reversed. (Barker (1991b)) Cassiterite is most highly concentrated where alluvium has been most intensively reworked. Principal placers are present in alluvium of modern floodplains and in low fluvial terraces. Tin is also widespread but less concentrated in high-level terraces and is absent in the white-weathering gravels. (Barker (1991b))

Exploration and site history

Site: Sample data indicate successively lower channels became increasingly rich in cassiterite as gravels in higher channels were repeatedly reworked. The present buried channel of No Name Creek would therefore be the product of still further reworking. (Barker (1991))
History: Investigations of mineral resources in the Ray River and Ft. Hamlin Hills area has been conducted intermittently by the U.S. Bureau of Mines during the years 1975 through 1989. Initially the work was part of a broader Trans-Alaska pipeline corridor reconnaissance conducted at the time of excavations associated with pipeline construction. The region contains very poor bedrock exposure and little was known of the geology prior to the construction. (Barker (1991))
