Xem tất cả trên Wikipediahttps://en.wikipedia.org/wiki/Sedimentary_rockSedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a

Xem thêmSediment transport and deposition
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into...

Sedimentary structures include all kinds of features in sediments and sedimentary rocks, formed at the time of deposition.
Sediments and sedimentary rocks are characterized by bedding, which occurs when layers of sediment, with different particle sizes are deposited on top of each other. These beds range from millimeters to centimeters thick and can even go to meters or multiple meters thick.Wikipedia · Nội dung trong CC-BY-SA giấy phép - https://en.wikipedia.org/wiki/Sedimentology
- Sedimentology encompasses the study of modern sediments such as sand, silt, and clay, and the processes that result in their formation, transport, deposition and diagenesis. Sedimentologists apply their understanding of modern processes to interpret geologic history through observations of sedimentary rocks and sedimentary structures. Sedimentary r...

Squeezed and compressed over time, the sediments become 'consolidated' (made solid) into layers of rock. Stratigraphyis the study of those layers Cementation occurs when dissolved mineralcomponents deposit in the interstices of sediments. It is the sticking together of sediment that forms a rock. Otherwise, rocks may ha…- Thời gian đọc ước tính: 4 phút

- Sedimentary basins are regions of the Earth where long-term subsidence creates accommodation space for accumulation of sediments. As the sediments are buried, they are subject to increasing pressure and begin the processes of compaction and lithification that transform them into sedimentary rock. Sedimentary basins occur in diverse geological setti...
