When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone. When there is a significant amount of clay or silt, geologists refer to the rock as argillaceous sandstone. The color of sandstone varies, depending on its composition. The sandstone was deposited on a nearly flat plane, but the beds below were laid down on a sloping surface, rather like brush strokes going one way and then another way on a canvas. Cross-beds are the groups of inclined layers, and the sloping layers are known as cross strata. Cross bedding forms on a sloping surface such as ripple marks and dunes, …Sedimentary rock - Clastic, Chemical, Organic: There are many different systems of classifying sandstones, but the most commonly used schemes incorporate both texture (the presence and amount of either interstitial matrix—i.e., clasts with diameters finer than 0.03 millimetre—or chemical cement) and mineralogy (the relative amount of quartz and the relative abundance of rock fragments to ...
