Multiple photos available
Josephine Creek placers, Josephine Creek District, Josephine Co., Oregon, USA

Field of View: 203 μm

SEM image of polished section of Josephinite pebble. Rounded 19 μm grain of Tetrataenite (in the lower left corner) divided from surrounding masses of low-nickeloan Awaruite by dark rim of Andradite. Large dark inclusion in Awaruite is Pyrrhotite (at the upper right corner) with small (<1 μm) very bright grain of native Silver. The small medium dark grain to right from micron bar is Pentlandite. The dark angular inclusion close to center is Andradite, the similar dark phase along the left side is Goethite. Analythical data are available at the daughter photo.
