Sandstone is a sedimentary rock composed primarily of sand-sized mineral particles, mostly quartz. This rock forms through the compaction and cementation of sand particles over long geological periods, often in riverbeds, beaches, and deserts. Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains, cemented together by another mineral.
Understanding the Context
Sandstones comprise about 20–25% of all sedimentary rocks. Sandstone is one of the most widespread sedimentary rocks on Earth, formed through the accumulation and cementation of mineral grains — mainly quartz and feldspar. These grains, carried by wind, rivers, or ocean waves, slowly build up layers that preserve the history of ancient environments. What is Sandstone?

Key Insights
Sandstone is a sedimentary rock composed of sand-size grains of mineral, rock, or organic material. It also contains a cementing material that binds the sand grains together and may contain a matrix of silt- or clay-size particles that occupy the spaces between the sand grains. Sandstone, lithified accumulation of sand-sized grains (0.063 to 2 mm [0.0025 to 0.08 inch] in diameter). It is the second most common sedimentary rock after shale, constituting about 10 to 20 percent of the sedimentary rocks in the Earth’s crust. Sandstone is a sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains.
