|Sphalerite on Prehnite
|Millington Quarry, Bernards Township, Somerset County, New Jersey
|Two large compound crystals to 8 mm across of translucent dark-yellow sphalerite on translucent green botryoidal prehnite on basalt. Sphalerite crystals (a sulfide mineral) are rare in NJ zeolite cavities and these were the largest I ever collected.
