Some of these sandstones are sideritic or pyritic, to the dismay of people building with the sandstone, when patches can go brown after a few years exposure to the sun. Acidic (humic rich) groundwaters can dissolve the siderite and leach the iron out, where fluctuating wet/dry cycles can oxide them, largely near-surface or in the joints. ...Fig. 6 Lithologic column of the Dömörkapu-Kis-rét type-section and the Vágotpuszta-2 (Vp-2) borehole (mod- - "Sideritic—kaolinitic and green clay layers in the Mecsek Mountains (SW Hungary): Indicators of Middle Triassic volcanism—Myth or reality?"The paper presents the lithological, mineralogical, and geochemical characteristics of the composition, structure, and organic matter of siderite nodules and host mudstones in the Lower Carboniferous (Tournaisian-Visean) siderite-bearing sequence exposed along the Kozhym River on the western slope of the Subpolar Urals.

It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate.The Cambay Shale group is conformable and 220–470 m thick, composed of monotonous grey shales in thin alterations with silty and carbonaceous shales, occasionally sideritic.
