Zircosulfate
Zircosulfate is a rare hydrated sulfate mineral with the chemical formula (Zr,Ti)(SO4)2 * 4H2O. It belongs to the orthorhombic crystal system and is classified in the Strunz system as 7.CD.50 and in the Dana system as 29.9.2.1. The mineral is composed of zirconium and titanium in its sulfate framework, with four water molecules incorporated into its structure. It exhibits a vitreous luster and typically appears white to colorless. Zircosulfate has a relatively low hardness and a low to moderate density. It is part of the sulfate mineral group, a class of minerals characterized by the presence of the sulfate ion (SO4^2-) in their chemical composition.
Overview
Zircosulfate is a rare hydrated sulfate mineral with the chemical formula (Zr,Ti)(SO4)2 * 4H2O. It belongs to the orthorhombic crystal system and is classified in the Strunz system as 7.CD.50 and in the Dana system as 29.9.2.1. The mineral is composed of zirconium and titanium in its sulfate framework, with four water molecules incorporated into its structure. It exhibits a vitreous luster and typically appears white to colorless. Zircosulfate has a relatively low hardness and a low to moderate density. It is part of the sulfate mineral group, a class of minerals characterized by the presence of the sulfate ion (SO4^2-) in their chemical composition.
Etymology
Zircosulfate is named after the sulfate ion, reflecting its sulfate-based chemical composition. The IMA approved the name for this mineral, but no specific discovery year or person is mentioned in the facts.
How to recognize it
Zircosulfate can be identified by its vitreous luster and white to colorless color. It has a relatively low hardness on the Mohs scale, though the exact value is not provided. Its low to moderate density can be estimated by comparing its weight to similar minerals. A streak test may help confirm its color when powdered. Due to its rarity and lack of distinguishing features, it may be confused with other sulfate minerals that share similar physical properties.
Trivia
Zircosulfate is notable for its unique combination of zirconium and titanium in a sulfate structure, which is uncommon in mineral chemistry. It is also one of the few sulfate minerals that incorporate both zirconium and titanium in its formula. The mineral's name is directly derived from the sulfate ion, which is a rare naming convention in mineralogy.
