The formation of sandstone occurs mostly into two phases, sedimentation/accumulation & compaction. Sedimentation of sand particles takes place either through water or air. Compaction occurs with physical pressure and chemical changes. The steps are:
  1. Sedimentation of quartz crystals
  2. Formation of cement & matrix
  3. Formation of pores

Types of Sandstone Components

The first phase forms sand clasts or grains due to transportation of sand particles from the source. The second phase forms cement or binding material and matrix as filler between the framework grains or clasts. The pore space is a void where no clasts, cement, or matrix matter exists. Let’s know these components of sandstone with some details.
