Early thousands years ago, the probability of biological process of soda ash from sodium sulfate was revealed in Egyptian Wadi Naturn sediments. Every year the crude sesquioxide alkali crystallized and collected from the lakes was roughly the amount of the sulphate brought and reduced by the incoming river water.

早在几千年前的埃及Wadi Naturn沉积岩中便向人们揭示了芒硝生物制碱的可能性，每年从这些湖里结晶和采收的粗倍半碱与进水带入并产生还原的硫酸盐的量大致相当。

Iron oxides would continue to be formed or at least not to be dissolved under oxic conditions, and the sediments in brown to red color will then be dominant. While in a reducing environment, iron oxides will be dissolved, with the possible migration of iron ion in the ocean, and then buried as siderite, pyrite, or other ironbearing minerals.

氧化强氧化条件利于沉积物中氧化铁的持续产生或者至少保持不被溶解的状态，从而形成棕色-红色沉积物；还原条件利于沉积物中铁氧化物的溶解，形成菱铁矿、黄铁矿等形式的埋藏，并可能造成溶解铁在海洋内的迁移。
