Sandstone is a type of sedimentary rock formed when small sand grains gradually come together and harden over time. These grains typically consist of quartz, feldspar, and fragments of other rocks. These materials are transported and deposited by natural agents such as water wind or ice and over many years bind together to form solid rock.How Is Sandstone Formed?Sandstone forms when sand accumulated in places such as rivers lakes or seashores is layered compressed and eventually cemented over ti

Sandstone is a clastic sedimentary rock composed of mineral grains or rock fragments ranging in diameter from approximately 2 mm to 0.02 mm, typically bound together by chemical cements such as silica (SiO₂), calcite (CaCO₃), or iron oxide (FeO), or by a clay matrix. Sandstones, which are terrigenous—that is, of terrestrial origin—belong to the epiclastic class of sedimentary rocks. Their color varies depending on the minerals they contain: red results from the oxidation of iron minerals, green
