Sandstone Velpke is characterized by distinct amounts of syntaxial quartz overgrowth, iron oxides and pore-filling kaolinite. The feldspars are altered to kaolinite.Sandstone is a sedimentary rock composed mostly of quartz sand, but it can also contain significant amounts of feldspar, and sometimes silt and clay. Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone.

7.1 Weathering. Sediments and sedimentary minerals are products of weathering that involves the physical degradation and chemical alteration of rocks at the Earth’s surface. It is caused by chemical reactions involving air, water, salt, or acid, by freezing and thawing, and by plants and animals.

In sandstones, SEM-EDS is not so useful when the cements are mineralogically identical to detrital grains (e.g., quartz cement in quartz sandstones) where additional signals such as cathodoluminescence (CL) may be required.Rocks containing small- to medium-sized grains are generally called sandstone. The photos below in Figures 7.67, 7.68, and 7.69 show three examples. Most sandstones contain sand-sized (0.062 to 2 mm in longest dimension) quartz or feldspar grains.
