Study Notes
Lithification: The Final Step in the Rock Cycle
- The sedimentary rock cycle involves five geologic processes working together to recycle sedimentary materials on Earth.
- Weathering and erosion are the initial steps in the formation of sedimentary rocks, breaking down and moving rocks and soil via wind and rain.
- Sediments are transported by wind, rain, and bodies of water like rivers, lakes, and oceans, and are eventually deposited in different locations.
- Lithification, also known as diagenesis, is the process by which loose sediments combine to form sedimentary rocks.
- Three processes involved in lithification are compaction, cementation, and recrystallization.
- Compaction occurs when loose sediments pile up and the weight of overlying sediments causes new sedimentary rocks to form.
- Cementation involves dissolved minerals crystallizing and gluing sediment grains together.
- Recrystallization involves crystals dissolving in a solution and then becoming recrystallized to form new stable crystals, binding sediment grains together.
- Sandstone, siltstone, and shale are examples of sedimentary rocks formed by compaction.
- Salt, gypsum, and limestone are examples of sedimentary rocks formed by cementation, with table salt being derived from sodium chloride deposits.
- Recrystallization is associated with the weathering and breakdown of the skeletons and shells of dead animals, forming new chemical sedimentary rocks.
- The rock cycle involves a combination of processes that work together to form new sedimentary rocks, demonstrating the dynamic nature of Earth's geology.
