Aug 11, 2018 · Black sphalerite with high amount of Fe is called marmatite, yellow translucent gemmy crystals of sphalerite are called cleiophane and red sphalerites are known as ruby blende or ruby jack. Sometimes, sphalerite bands together with wurtzite, galena , pyrite , and marcasite into concentric layered shapes known as schalenblende . ent study was carried out on sphalerite crystals from different ores to determine the metal concentrations and their distributions. The study followed a phenomenological approach, i.e. using zoned crystals of sphalerite and assuming that their banding is primary, acquired during crystal growth from a ß uid independently of the minerogenic context.Sphalerite can be difficult to identify because of its variable luster, color, abundant but obscured cleavage and crystal habits.
