Types of Sedimentary Rocks

Sedimentary rocks formed from fragments of pre-existing rocks. Composed of solid particles (clasts) transported and deposited. Examples: sandstone, shale, conglomerate.

Sedimentary rocks formed by precipitation of minerals from solution in water bodies due to evaporation or chemical activity. Examples: limestone, rock salt.

Sedimentary rocks formed from the accumulation of organic material. Derived from the remains of plants and animals. Examples: coal, some limestones.

A fine-grained detrital sedimentary rock. Composed of clay-sized particles. Characterized by its fissility.

A fine-grained detrital sedimentary rock. Similar to shale but lacks fissility. Composed of clay and silt-sized particles.

A medium-grained detrital sedimentary rock. Composed primarily of sand-sized grains. Classified based on composition and texture.

A type of sandstone with abundant feldspar grains.

A sandstone that contains less than 15% mud. It is a relatively clean sandstone.

A poorly sorted sandstone with a significant amount of clay. Often contains rock fragments and dark-colored minerals.

A coarse-grained detrital sedimentary rock. Composed of rounded gravel-sized clasts. Indicates high-energy depositional environments.
