Some put it at 20%, others at 25% or 30%. A more widely accepted is sandstone or feldspathic sandstone with at least 25% feldspar. Sometimes the term feldspathic sandstone or feldspathic arenites may refer to arkoses.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. Sandstone. Sandstone is made of sand grains (0.05mm to 2mm) that may have been deposited in the sea, by rivers, or in deserts, and later cemented together by minerals precipitated from groundwater. Most sandstones are made up largely of quartz grains, because quartz is a very hard and chemically-resistant mineral. Quartzite is a name given to ...Sandstone is very often visibly layered.
