Iron(II) carbonate, or ferrous carbonate, is a chemical compound with formula FeCO 3, that occurs naturally as the mineral siderite. At ordinary ambient temperatures, it is a green-brown ionic solid consisting of iron(II) cations Fe and carbonate anions CO 3. Web(2) The hydrogen sulfide to ferrous iron ratio is less than 2 (H 2 S/Fe 2+ < 2). If H 2 S/Fe 2+ > 2, Fe 2+ is efficiently converted to pyrite and the concentration of dissolved iron in seawater decreases. Therefore, the seawater constitute an anoxic and iron-rich environment (H 2 S/Fe 2+ < 2) rather than an anoxic and sulfide environment [ 6 ].
