20. Carbonate Sedimentation In Marine Environments

21. -:Carbonate occur in 1- Eulittoral and supralittoral env. ( principally in tropical and subtropical env.) 2- Sublittoral env. (in water depth approximately between (20-200 m) (shelf and shelf margin) 3- deep sea (down to the calcite compensation depth between 4000- 5000 m (primarily planktonic sedimentation )

64. Evolution of Carbonate Sequences

65. SummaryVariations in carbonate depositional settings through time produce corresponding changes in their lateral and vertical facies geometry. High frequency changes in facies are induced by sea level, and climate, whereas long-term low frequency changes are commonly related to paleo-geography and plate configurations or the evolutionary changes in the carbonate producing organisms. The sections below provide a general and classical introduction to the eclectic responses of carbonates to changes in their setting.

66. Controls On Carbonate Deposition

67. The geometry and facies relationships of carbonate accumulations are closely tied to the paleogeographic setting and changes in that setting through time, particularly water depth variation. Paleolatitude and clastic influx are major influences on the distribution of the carbonates, with facies largely controlled by the proximity of the depositional basin to open marine circulation and the position of the depositional setting within the basin. carbonate sediments and their associated buildups are largely the by products of organisms whose evolution has a significant influence on carbonate deposition. Wilson (1975) reviews in detail some of the similarities and differences that occur in carbonates of different ages.
