    Another common cementing agent in sandstone is iron oxide, also called hematite cement. The iron present in the cement will give the sandstone a distinctive red color. According to the Stone Care Techniques website, iron oxide cemented sandstone weather well in dry climates and become harder and stronger, resisting weathering and deterioration.

  • Cementation (geology) - Wikipedia

    Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary grains. The new pore-filling minerals forms "bridges" between original sediment grains, thereby binding them together. In this way sand becomes "sandstone", and gravel becomes "conglomerate" or "breccia". Cementation occurs as part of the diagenesis or lithification of ...

  • Sandstone - Wikipedia

    OverviewOriginsComponentsTypes of sandstoneUsesSee alsoNotesBibliography

    Sandstones are clastic in origin (as opposed to either organic, like chalk and coal, or chemical, like gypsum and jasper). They are formed from cemented grains that may either be fragments of a pre-existing rock or be mono-minerallic crystals. The cements binding these grains together are typically calcite, clays, and silica. Grain sizes in sands are defined (in geology) within the range of 0.0625 mm to 2 mm (0.0025–0.08 inches). Clays and sediments with smaller grain sizes not visible with the naked eye, including siltstones
