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.
Explore the process of lithification, where sediments combine to form sedimentary rocks through compaction, cementation, and recrystallization. Discover how intense pressure, crystallization of dissolved minerals, and mineral transformation play key roles in the formation of sedimentary rocks.
