Study Notes
- Lithification is the process by which sediments combine to form sedimentary rocks, derived from the Greek word "lithos" meaning rock.
- Two main ways lithification occurs are compaction and cementation, with a third method being recrystallization for certain sediments.
- Compaction involves the consolidation of sediments under intense pressure from overlying deposits, rearranging grains and reducing pore spaces.
- Cementation is the process where dissolved minerals crystallize and bind sediment grains together, forming sedimentary rocks.
- Recrystallization is the transformation of unstable minerals into stable ones, causing grains to bind together, commonly seen in the formation of limestone and other chemical sedimentary rocks.
