Study Notes
Types of Sedimentary Rocks
- Sedimentary rocks are classified into three main types: Clastic, Chemical, and Organic.
Clastic Rocks
- Formed from the accumulation and compaction of broken fragments of other rocks.
- Classified based on the size of rock fragments, which can range from coarse gravel to fine clay.
- Examples include sandstone, shale, and conglomerate.
Chemical Rocks
- Created through the crystallization of dissolved minerals from solutions, often occurring during evaporation.
- Commonly found in environments where water is abundant but might evaporate, leading to mineral deposit formation.
- Notable examples include limestone, rock salt, and gypsum.
Organic Rocks
- Composed primarily of the remains of plants and animals, forming in layers over time.
- Indicative of past biological activity and often rich in fossils.
- Key examples include coal, made from compressed plant material, and some types of limestone formed from shell debris.
