Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock.Sandstone is a clastic sedimentary rock. It is the most common sedimentary rock found in sedimentary basins worldwide.Three Types of Rock. Rocks fall into these three groups: Igneous , Sedimentary , and Metamorphic. Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure …8. Clay: Clay is a type of rock that is composed of very fine-grained minerals.
