Sandstone is a sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. It is one of the most common sedimentary rocks, making up about 20–25% of all sedimentary rocks. Sandstone is a clastic sedimentary rock, meaning it's formed from cemented pieces of other rocks and minerals.

The mode of deposition of sand and gravel is most commonly derived from the action of water in rivers, lakes or oceans. The water velocity and turbulence, combined with the settling rate of the particles, determine the movement of sand and gravels by suspension (sweeping free of the stream bed), saltation (bouncing), or traction (rolling, sliding or tumbling).

Mechanical grit removal systems are an integral part of wastewater treatment, designed to separate heavier inorganic materials, such as sand, silt, and gravel, from organic waste. These systems improve the efficiency of downstream processes by preventing abrasion and accumulation of grit in equipment and pipelines.

A classic example of this is the conversion of organic matter (peaty material, dead critters) to the various components of oil and gas (hydrocarbons). The optimum temp for this process is between 80 o-120 o C, which in many places means the sediments have been buried beneath 3 km or more of rock.

People who collect sand as a hobby are arenophiles. Sand vs Silt vs Gravel. The primary difference between sand, silt, and gravel is the size of their particles. Silt is finer than sand, with particles less than 0.0625 mm, often giving it a smoother feel. Gravel, conversely, is coarser, with particle sizes above 2 mm.

Aggregate crushing is the process of breaking down the large pieces into smaller particles. Screening – different sized aggregates are required for different types of construction projects and materials – thus they need separating. Construction aggregates can also be produced from naturally occurring deposits such as sand and gravel.
