In mineralogy terms the difference between sphalerite and marmatite. is that sphalerite is a yellow, brown or black, sometimes red, green white or colorless mineral with cubic crystals, of a chemical formula (Zn,Fe)S while marmatite is a dark form of sphalerite that is rich in iron. tite < sphalerite < chalcopyrite < pyrite, but it is unknown if this sequence also applies to the seafloor environment. The common presence of sphalerite in seafloor gossans suggests that sphalerite, or at least Fe-poor varieties, may be resistant to oxidation. Some nonferrous sulfides, such as galena, are highly resistant to oxidative weathering.
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. Since the number of atoms in a single unit cell of Zn and S is the same, it is consistent with the formula ZnS. The ionic radius for Zn 2+ is 74pm and for S 2-is 190pm. . Therefore the ratio between cationic and anionic radii in zinc blend is 0.39 (74pm/190 pm) .This suggests a tetrahedral ion arrangement and four nearest neighbors from standard crystal structure prediction♡ Sphalerite is a mineral composed of zinc sulfide, and it is an important ore of zinc.
