GEOLOGY

Detailed explanation-1: -Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains.

Detailed explanation-2: -Sandstones are composed of particles with an average size of between 2.00 and 0.0625 mm in diameter. They have four constituents: grains, matrix, cement, and, sometimes, porosity (Figure 1). Sand-sized particles form the framework of the rock.

Detailed explanation-3: -Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles or rock fragments. It is a common rock type that is found all around the world, often forming in areas where there is a lot of sand accumulation, such as in deserts, riverbeds, or coastal areas.

Detailed explanation-4: -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.

Detailed explanation-5: -Sandstone is a type of rock made from sediment-a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock.
