Sandstone is a classic sedimentary rock comprising mainly of minerals that are formed from sand. This stone gains its distinctive formation throughout centuries of sand deposits forming in rivers, on the ocean floor, or lakes. All of these elements combine with minerals like calcite or quartz and compress over time. The pressure causes the minerals to come together and form sandstone.
The Process of Sandstone Formation
Layers of sand first amass due to the sedimentation process. The particles settle within the fluid and rest against some barricades either from air/water. The stone becomes cemented by the excessive pressure precipitated between the sand grains.
This stone is formed from the sands of older rocks that get fragmented over time. It goes to create a stone that contains sand in the range of 1/16thmm-2 mm. Millions and millions of these fine grains of sand make up a sandstone block, and the effect of compression helps form this superb stone.
Sand is the most common component in sandstone, and that’s’ where it derives its name. But matrix cement and other similar materials may also often be present in the sandstone. The cement in the stone is generally comprised of calcium carbonate, iron oxide, or quartz.
If it holds excessive amounts of cement, it affects the quality of this natural stone. Sandstone can be created where the conditions are suitable for its formation, and as mentioned, this occurs mostly in lakes, rivers, beaches, desert dunes, and the ocean floor.
Variations of Sandstone
Sandstone has many natural variations in tone, shade, grain, and colour. Some of the stones have specific oxidising properties while some others may have unchanging banding. It can be found throughout the world, and large deposits of sandstone are present in the US and South Africa (where the stone is found in eight different varieties). Germany has the most sandstone deposit locations in the world.
Even Australia has massive deposits of sandstone. We boast an enormous variety of colours and textures and the best quality of sandstone.
