Sphalerite: The primary ore of zinc and a collector's gem.

Geologic Occurrence. Many minable deposits of sphalerite are found where hydrothermal activity or contact metamorphism has brought hot, acidic, zinc-bearing fluids in contact with carbonate rocks. There, sphalerite can be deposited in veins, fractures, and cavities, or it can form as mineralizations or replacements of its host rocks.

Sphalerite The Zinc Blende

Sphalerite is common, but it does not often show up in casual collections of minerals, despite its occurrence in several different colors. This is perhaps because sphalerite is most commonly found in black or dark gray due to the frequent presence of iron impurities in its makeup. Sphalerite has been previously called blende or later zinc blende.

Mineral Database National Museum Wales

Occurrence in Wales: sphalerite is widely developed in Wales and was extensively mined as an ore of zinc in many areas. However, unlike copper, lead, gold and silver, zinc metal was not extracted commercially in Europe until about 260 years ago when William and John Champion devised processes to recover the metal firstly from calamine (smithsonite) and then from sphalerite.

Galena and Sphalerite in the Fayette at Orchard Salt Dome

Galena (PbS) and sphalerite (ZnS) have been found at several of the salt domes of the Coastal Plain of Texas and Louisiana, but seldom have these occurrences been found outside the dome proper.For this reason, and the bearing it may have on the origin of the galena and sphalerite, the extradomal occurrence in the Fayette 2 here mentioned may be of sufficient interest to be worth recording.
