Sedimentary Rock Samples
Sedimentary Rock Samples provide a detailed record of processes that occur at or near the Earth’s surface. These rocks form through the accumulation, compaction, and cementation of sediments such as sand, silt, clay, and organic material.
Sedimentary Rocks fall into three main categories, all of which you get samples of from Wiltronics Online:
- Clastic sedimentary rocks, such as sandstone and shale, form from fragments of pre-existing rocks that have been broken down by weathering and erosion.
- Chemical sedimentary rocks, such as banded iron formation and gypsum, develop when minerals precipitate from evaporating water.
- Organic sedimentary rocks, such as coal, form from the remains of plants and animals, often in marine or swamp environments.
