Clastic Sedimentary Rocks
- Conglomerate: Composed of large, rounded rock fragments (gravel) cemented together.
- Breccia: Similar to conglomerate, but composed of angular rock fragments.
- Sandstone: Formed from cemented sand grains.
- Mudstone: Formed from compacted fine-grained mud or clay.
- Siltstone: Intermediate in grain size between sandstone and mudstone.
Chemical Sedimentary Rocks
- Limestone: Composed primarily of calcium carbonate (calcite).
- Dolomite: Composed primarily of calcium magnesium carbonate (dolomite).
- Chalk: A soft, white limestone composed of microscopic calcite crystals.
- Gypsum: Formed from precipitated calcium sulfate.
- Halite (rock salt): Formed from evaporated seawater.
Biochemical Sedimentary Rocks
- Coal: Formed from the accumulation and compaction of plant materials.
- Lignite: A low-grade coal with high moisture content.
- Anthracite: A high-grade coal with low moisture content.
- Chert: A hard, fine-grained rock composed of silica (silicon dioxide).
- Flint: A dark-colored variety of chert.
Other Types
- Evaporite: Formed from the precipitation of minerals from evaporated water bodies.
- Iron formation: A banded rock composed of iron oxides and silica.
- Banded iron formation: A type of iron formation with alternating bands of iron oxides and silica.
- Volcaniclastic sedimentary rocks: Formed from the accumulation and compaction of volcanic ash and other volcanic particles.
