Brief introduction of ferrous carbonate

Post by minhua »

Siderite is very common Iron Carbonate found associated with sedimentary deposits of sand and shale. It can act as a cementing agent in sandstones helping to lithify the rock. It is abundant in deltaic environments and tends to form nodules in the pro delta muds. It is a brown to reddish brown color and reacts with hydrochloric acid .
Ferrous carbonate is the precipitated result of the reaction of ferrous sulphate and sodium carbonate in an aqueous medium. This results in a tan brown to reddish brown powder that is used mainly to fortify foods containing iron, and as an acidity regulatorUsed to change or maintain a pH which can be either acidic or basic. They can be organic, minerals, acids, bases, neutralizing agents or buffering agents in food.
Ferrous carbonate is commonly found in hydrothermal veins, and is associated with barite, fluorite, galena, and others. It is also a common diagenetic mineral in shales and sandstones, where it sometimes forms concretions. In addition, a number of recent studies have used the oxygen isotopic composition of sphaerosiderite as a proxy for the isotopic composition of meteoric water shortly after deposition.
