Goethite, Pyrite

Locality: Clackamas River Localities, Clackamas Co., Oregon, USA

Posted by: Steve Sorrell

There are quite a few images of acicular or filiform pyrite from the Clackamas River localities on Mindat, but none that look like this one. This specimen doesn't have a specific locality, just Clackamas River, and was acquired by Joan Lamond (Melbourne) from Sid Sparkes in Vancouver in 1985. The original pyrite, now altered to goethite, has taken a couple of right angle turns, and produced a pair of octahedral pyrite crystals. An interesting specimen! Picture width is 4mm.
