galena crystal with chalcopyrite crystals
Tri-State district
This specimen is an attractive combination of two minerals, galena and chalcopyrite. 
Chalcopyrite is an iron copper sulfide and an important ore of copper. 
The chalcopyrite crystals are the bright metallic yellow crystals sitting on top of a
gray, cubic galena crystal.
