Popularly known by the name “stone of creativity”, Sandstones are defined as sand particles cemented together into a rock. These stones are a type of rock made of sediments, and that is why they are called the sedimentary rocks. Sedimentary rock is a name provided to a stone if the cluster arrangement of that stone includes clasts, pieces of minerals, and rocks’ fragments. Therefore, bagging the sandstones is a higher level of the category known as classic sedimentary rocks.

Further, Sedimentary rocks are basically made up of a bunch of medium-sized grains which are also known as framework grains. Hence, the sandstones can also be identified as medium-grained clastic sedimentary rocks.

Sandstones are formed in a very interesting and two-way process. The first consists of a layer of sand accumulating as the result of sedimentation either from water or air. And secondly, when the sand is accumulated, the sand turns into a sandstone when compacted by the pressure of overlying deposits and cemented minerals filling the pore spaces between sand grains.

Besides, composed of quartz sand and a significant amount of feldspar and sometimes silt and clay, these can also provide the sandstone with different sub-identities. Like, If a sandstone contains more than 25 per cent feldspar, these the stone can be categorized as Arkosic Sandstone. Similarly, If a sandstone contains more than 90 percent of quartz, this stone comes under Quartzose Sandstone’s banner. Lastly, when sandstone is formed with a combination of clay or silt, then this tone is known as Argillaceous Sandstone that basically shows a greyish blue shade of the color.
