What is Sandstone?
Sandstone is one of the most common kinds of clastic sedimentary rocks consists of sand-size (0.06 to 2 mm) clasts or grains of minerals and organic matters.
Formation of Sandstone
Under the sea
Under the Land
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:
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.

Classification of Sandstone
Framework Grain-based Classification:
According to Dott’s classification scheme, which is considering mineralogy of framework grains of the sandstone and percentages of clay matrix in between the grains. It has focused on quartz, feldspar, and lithic grains.
Thus, we can find the following types of sandstone rocks, mainly in nature.
It has less than 15% of the clay matrix between the framework grains. It can further classify as:
- Quartz Arenites: With more than 90% of quartz or siliceous grains.
- Feldspar Arenites: With less than 90% of Quartz grains.
- Lithic Arenites: With a high content of lithic fragments.
It has more than 15% of the clay matrix between the grains. It can further classify as:
- Quartz Wackes: With 90% of quartz. Its occurrence is uncommon.
- Feldspar Wackes: With at least 25% of feldspar.
- Lithic Wackes: With at least 25% of lithic grains.
It has more than 25% of feldspar. Here, the grains are rounded in ailing manner & less sorted.
It is a heterogeneous mixture of quartz grain, feldspar grains, and lithic fragments & surrounded by a fine-grained clay matrix.
In industry, geological terms are less understood and used the following cement-content or minerals-based classification popularly
It is cement-based mineralogy. So, the mineral content of the cementing material matters more in these types of classification mostly used in the industry by professionals.
- Siliceous – It contains a high percentage of silica or quartz particles.
- Calcareous – It has a high level of calcites in the cementing material.
- Argillaceous – It consists of clay particles in abundance.
- Ferruginous – It is rich in ferrous content.
