2016年1月12日 · Deltaic depositional facies result from interacting dynamics processes (wave energy, tidal regime, currents, climate, etc.), which modify and disperse riverborne clastic deposits. The term delta was first applied by the Greek philosopher Herodotus (490 B.C.) to the triangular land surface formed by deposits from Nile River distributaries.

Deltaic depositional facies result from interacting dynamics processes (wave energy, tidal regime, currents, climate, etc.), which modify and disperse riverborne (fluvial) clastic deposits. The term delta was first applied by the Greek philosopher Herodotus (490 B.C.) to the triangular land surface formed by deposits from Nile River distributaries.
Deltaic Environments - SEG Wiki
Deltas are depositional environments where a fluvial system’s mouth contacts an open or slow moving body of water, which typically is an ocean or sea. Deltas tend to form fan or triangular shaped deposits of sediment. [1] .
Lacustrine to deltaic depositional systems: Sedimentary evolution …
Upper Cretaceous continental lacustrine to deltaic depositional systems comprised the important petroleum reservoirs in the southern Songliao Basin, China, and their changes in depositional architecture reflected the interplay of tectonics, lake level change, and sediment supply.
Deltaic Deposit - an overview | ScienceDirect Topics
Deltaic deposits refer to sedimentary deposits formed by the accumulation of sediment in a delta, which is a landform created by the deposition of sediment where a river flows into an ocean, lake, or another body of water.
Depositional styles of deltaic systems from the inner shelf to …
2021年9月1日 · Depositional architectures of deltaic systems reveal that the basin kinetic condition varied from the inner shelf to shelf edge. Inner shelf braided river deltaic systems were dominated by fluvial processes, whereas middle–outer shelf meandering river delta and shelf edge incised river delta systems were reworked by waves and alongshore currents.

2024年8月26日 · Depositional environments. The influence of river, wave, and tide on deltaic sediments produces a complex mix of macroforms. Fluvial processes dominate in the upper delta plain, although this area can also be swampy with marshes and lakes present. The lower delta plain is subjected to marine influence, acting to modify the fluvial-derived ...
Topset deposits of a delta are mainly made up of marsh deposits and delta-front silts and sands. Also present are river channel deposits and natural levee deposits, together with crevasse splay deposits. Muddy sediments with shell layers are deposited in the bays between the distributaries and the tidal channels (SCRUTON, 1960).
Depositional Processes and Products in the Deltaic Environment
Four basic factors control and influence delta formation: (1) river regime, mainly particle size and quantity of material transported by a river to its delta and variations in these properties during seasonal fluctuations in flow ; (2) coastal processes, essentially the influence of waves, tides, and currents on the seaward margins of the ...

2018年4月4日 · Since the 1940s, the sedimentary environment, sedimentation, and depositional systems of the modern deltas of the Mississippi River, Rhone River, Niger River, Yangtze River, and Yellow River have been systematically and comprehensively investigated, and this has laid a theoretical basis for the establishment of a sedimentary facies model and sed...
