A type of sedimentary rock that contains a large quantity of weathered quartz grains.

A clastic sedimentary rock whose grains are predominantly sand-sized. The term is commonly used to imply consolidated sand or a rock made of predominantly quartz sand, although sandstones often contai [..]

A clastic sedimentary rock in which the particles are dominantly of sand size, from 0.062 mm to 2 mm in diameter.

1660s, from sand (n.) + stone (n.). So called from its composition.

Common sedimentary rock composed of sand-size mineral and rock grains cemented together as a mass.

A sedimentary rock consisting of quartz sand united by some cementing material, such as iron oxide or calcium carbonate.

rock formed by grains of sand.

Sedimentary rock composed of sand-sized clasts.

a soft sedimentary rock composed of feldspar and weathered quartz grains. Porous sandstone layers often hold water in aquifers.

A sedimentary rock composed of sand. Saphenous

A sedimentary rock formed mostly of sand grain.

Sandstones are sedimentary rocks usually composed of quartz cemented with silica, iron oxide or calcium carbonate. Sandstones range from very soft and friable to very hard and durable, depending on th [..]

A clastic sedimentary rock in which the particles are dominantly of sand size, from 0.062 mm to 2 mm in diameter. Quartz is the most abundant mineral that forms sandstone.

a cemented or otherwise compacted detrital sediment composed predominantly of sand-sized (2 to 0.063 mm) grains.

A clastic sedimentary rock in which the particles are dominantly of sand size, from 0.062 mm to 2 mm in diameter.

a medium-grained sedimentary rock with cemented grains more than 60 micrometres in size [sand; sandy]

(n) a sedimentary rock consisting of sand consolidated with some cement (clay or quartz etc.)

Sedimentary rock composed of small grains of mainly quartz and feldspar bound together by silica, carbonate, or clay minerals.

Sedimentary rock

Sandstone is a sedimentary rock formed as sand-sized minerals harden together over time. Dependent on grain size and mineral composition, sandstone has concentric banding and can exhibit a variety of earthy colors. Some sandstone even resembles wood grain. Most notable is the deep red sandstone quarried in the American Southwest. Sandstone is frequ [..]

Sedimentary rock made mostly of sand-sized grains.

A sedimentary rock composed mostly of mineral and rock fragments. Sandstone contains a minimum of 60% free silica. Sandstone is a soft, loose-knit stone that has a natural, rustic look.

a sedimentary rock, comprising of feldspar and quartz particles.

A cemented or compacted detrital sediment composed predominantly of quartz grains the size of sand particles.

a type of sedimentary rock made of sand grains cemented together.

A clastic sedimentary rock composed of grains of sand size set in a matrix of silt or clay and more or less firmly united by a cementing material (commonly silica, iron oxide, or calcium carbonate); t [..]

a sedimentary rock consisting of usually quartz sand united by some cement (such as silica or calcium carbonate)

A  sedimentary rock composed predominantly of sand-sized quartz grains.

A detrital, sedimentary rock composed of individual grains of sand (commonly quartz) that are cemented together by silica, calcium carbonate, iron oxide or other cements. Sandstone is a common rock in [..]

a type of rock composed primarily of quartz grains. Often forms an excellent reservoir for oil and gas

A compacted sedimentary rock composed of detrital grains of sand, mostly quartz. If the void spaces between the grains are open and free of other minerals, it may become a reservoir for oil or gas.

Rock composed mainly of sand-sized particles or fragments of the mineral quartz.

A sedimentary rock made up of sand-size grains that usually consist of quartz more or less firmly united by some cement (as silica, iron oxide, or calcium carbonate).

A sedimentary rock composed predominantly of sand sized grains, usually quartz. 

A sedimentary rock composed of individual mineral grains of rock fragments between 0.06 and 2 millimeters (0.002 and 0.079 inches) in diameter and cemented together by silica, calcite, iron oxide, and so forth.

Sand that has turned into a rock due to geological processes

A sedimentary rock composed of mostly cemented quarts grains.

hardness and colour vary: may fracture or be too hard to carve easily, depending on the amount of quartz contained

A sedimentary rock produced by the consolidation and compaction of sand, cemented with clay etc. en|metasandstone
