Veins.
Accumulating deposits of sand from wind or water deposition are initially created. The weight from the deposits above cause compaction of the lower deposits. Compaction forces out air and water that exists between the sand grains. Minerals form from the remaining concentrated solutions in a process called precipitation. These minerals act as a cement which binds the particles of sand together, creating sandstone.
In Formation was created in 1982.
