2019-1-23 · Sandstone is a clastic sedimentary reservoir rock composed of mainly quartz and/or feldspars, and typically deposited by relatively high-energy processes, which winnow out much of the fine particle size fraction while transporting and depositing the coarser (sand-sized) particles. Like sand, sandstone may be any color, but the most common colors are tan, brown, yellow, red, grey, pink, …
Commercial sandstone is a lithified sand that chiefly comprises quartz or quartz and feldspar with a fragmental (clastic) texture. Sandstone contains interstitial cementing materials, such as calcite, clay, iron oxides, or silica. Arkose (abundant feldspar grains), graywacke (abundant angular rock fragments), and conglomerate (abundant rounded rock fragments) are included in this category.
2021-11-4 · Sandstone is a tough, durable rock formed of sand mineral particles, and is widely used in architecture and construction. Red sandstone is a subcategory of sandstone, with its red hue derived from iron oxide in the rock. Red sandstone is popular for its warm, rich textures, and is used in cladding facades, landscaping, and internal surfaces.
