- Fragments form clastic sedimentary rock
- Dissolved ions form chemical sedimentary rocks
- Precipitates - such as halite
- Generally carbonates, halides, some oxides
- Also are the cement for clastic materials
- Lithification - sediments of either type accumulate in layers, compress under their own mass and/or what buries them, and, with cements, form a hardened mass
