Sedimentology is the study of sediment and the processes that form and transport it. Sedimentology is an important aspect of stratigraphy because sedimentary rocks make up a large portion of the Earth's crust and contain valuable information about the Earth's history. Sedimentologists use a variety of techniques, including field observations ...
Each sediment wave field consists of several to tens of rows of sediment waves, with a size up to 2.8–7.2 km in wavelength and 30–60 m in wave height ( Figure 4.12 B). They are mostly asymmetrical in cross sections with a thicker upslope flank and a thinner downslope flank, indicating upslope migration.
One of the key principles of sedimentary geology is that the ability of a moving medium (air or water) to move sedimentary particles—and keep them moving—is dependent on the velocity of flow. The faster the medium flows, the larger the particles it can move. This is illustrated in Figure 6.1.3 6.1. 3.
Menurut Krumbein dan Sloss (1971) sedimentasi berdasarkan ilmu geologi dan sratigrafi adalah proses-proses yang berperan atas terbentuknya batuan sedimen. Selanjutnya disebutkan bahwa urutan proses sedimentasi adalah meliputi proses : pelapukan, perpindahan, deposisi (sedimentasi), serta lithifikasi (pembatuan). (Adhe, 2014).
Sediment, sedimentation. Sediment consists of mineral and organic particles that are displaced by a variety of surface and mass erosion processes (see entry on Soil Erosion ). Sedimentation is a more general term relating to the entrainment, transport and deposition of sediments. Erosion and sedimentation are important natural processes that ...
Sediment is solid material that is moved and deposited in a new location. Sediment can consist of rocks and minerals, as well as the remains of plants and animals. It can be as small as a grain of sand or as large as a boulder. Sediment moves from one place to another through the process of erosion. Erosion is the removal and …

Sediment (e.g., silt) resulting from soil erosion or construction activity can be carried into water bodies by surface runoff. Suspended sediment interferes with the penetration of sunlight and upsets the …
Batuan sedimen. Perlapisan batuan sedimen di Sukabumi, Jawa Barat, Indonesia. Batuan sedimen atau batuan endapan [1] adalah batuan yang terbentuk di permukaan bumi pada kondisi temperatur dan tekanan yang rendah. Batuan ini berasal dari batuan yang lebih dahulu terbentuk, yang mengalami pelapukan, erosi, dan kemudian …
Deposition is a natural geological process that transports sand, silt, and sediment from one place and deposits it in another. Agents like water, wind, gravity, and glaciers carry out this transportation. ...
Streams have a major role in geology. Streams sculpt and shape the earth's surface by eroding, transporting, and depositing sediment. By eroding sediment from uplifted areas and creating landforms made of deposited sediment in lower areas, streams shape the earth's surface more than glaciers do, more than waves on a beach do, and far more ...
sedimentation, in the geological sciences, process of deposition of a solid material from a state of suspension or solution in a fluid (usually air or water). Broadly defined it also includes deposits from glacial ice and those materials collected under the impetus of gravity alone, as in talus deposits, or accumulations of rock debris at the base of cliffs.
sedimentary rock, rock formed at or near Earth's surface by the accumulation and lithification of sediment (detrital rock) or by the precipitation from …
The purposes of this study are to identify subsurface geological structures, delineating sediment sub-basin and to estimate sediment thickness in the southern Akimeugah basin. Data analysis used ...

Bedding Planes. Figure 5.4.1 5.4. 1: Horizontal strata in southern Utah. The most basic sedimentary structure is bedding planes, the planes that separate the layers or strata in sedimentary and some volcanic rocks. Visible in exposed outcroppings, each bedding plane indicates a change in sediment deposition conditions.
