Formation of diagenetic siderite in modern ferruginous ...

Spheroidal siderite is often inferred to be a water-column precipitate and precursor for rhombohedral and cemented diagenetic siderites in Precambrian rocks (Konhauser et al., 2005; Köhler et al., 2013). In contrast, the preservation of residual phases trapped in spheroidal mosaic siderite crystals in Lake Towuti may, if primary, suggest ...

The observation that the precursor sediments comprised greenalite and diagenetic siderite is consistent with experimental evidence for the rapid precipitation of Fe(II)-silicates from anoxic solutions simulating Archean seawater (Konhauser et al., 2007; Tosca et al., 2016, Tosca et al., 2019; Jiang and Tosca, 2019).

2018-12-18  Previous studies concluded that organic matter, in association with Fe(III) mineral precipitates, forms spherical siderite structures under diagenetic conditions (Kohler et al. 2012). Rhombohedral siderite seen in the sample could have formed from a spheroidal siderite precursor, accounting for the spheroidal voids in some siderite cores.
