Field of view: 30 mm. Euhedral crystals of pyrite. The yellow cubes are pyrite. The brown host is siliceous shale.
Recovered from siliceous shale, a matrix of accretionay complex, near a bedded manganese deposit subjected to Albite-Epidote-hornfels facies contact metamorphism.
Pyrite from this location was described in 2012.
