Pure sphalerite is colorless and rare. Normally, iron is present, causing the color to vary from pale greenish yellow to brown and black with increasing iron content. When iron content is high it is an opaque black variety, marmatite. Sphalerite is easily identified by its cleavage and its resinous luster. The best specimens of sphalerite found in Kansas are from the lead and zinc mines of Cherokee County. Sphalerite is also found as small crystals in clay-ironstone concretions in the Pennsylvanian shales of eastern Kansas. Chalcopyrite (hardness 3 1/2-4) Sphalerite is a polymorph with two minerals, wurtzite and matraite. The three are called polymorphs (meaning many shapes) because although they have the same chemistry, (Zn, Fe)S or zinc iron sulfide, they have different structures and therefore different shapes. Sphalerite is by far the more common mineral of the three.Macro shooting of natural mineral rock specimen - Sphalerite stone on white marble background from Dalnegorsk region of Primorsky.

The principal sphalerite deposits are massive mixed sulfide deposits in metamorphic rocks and replacement stratabound deposits in carbonate rocks; they are often associated with sulfides of lead and copper. The hard-rock zinc ores are mined by open-pit or underground mining techniques. Sphalerite: Galena and sphalerite commonly occur together and darker varieties of sphalerite may initially be confused with galena. Pure sphalerite samples can be distinguished from galena because they are harder (3.5 to 4) and have a lower specific gravity (3.9-4.1). The color of their streak provides an even simpler way to distinguish the two.The weathering of sphalerite above massive primary sulfide deposits usually depicts a yellow-brown color with coarse cellular box work and sponge structure (Fig. 5.6).The primary mineral sphalerite (ZnS) often changes to willemite (Zn 2 SiO 4).Gossans of multisulfide deposits are often associated with typical contour box work from silver-rich tetrahedrite …Sphalerite has been mined from the Hutson Mine in Livingston County, and the Lexington Quarry Co . has mined sphalerite from a vein deposit in Jessamine County for several years, producing very fine, dark brown to black, tetrahedral crystals.
