Lab 7: Sandstone

Sandstone is a sedimentary rock composed of sand-sized grains of mineral, rock or organic material. It also contains a matrix of silt- or clay-size particles that occupy the spaces between the sand grains, cementing them together. Sandstone is found in sedimentary basins around the world, being one of the most common types of sedimentary rocks. It is mined in many parts of the world and used as both a construction material and as a raw material. It also serves as a reservoir for oil and natural gas.
