Clastic shelf deposits Sedimentation on continental shelves (where ocean depths are less than m) are continuous with coastal plain sequences. In clear tropical waters these accumulate abundant carbonates (to be considered later), but in cold water or areas with high siliciclastic inputs, the shelves are covered by fine sands, silts, and muds.

The Permian basin provides the classical model for carbonate and clastic reciprocal sedimentation model originally proposed by Van Siclen () and others. In this model, there was rapid accumulation of a broad belt of carbonate and evaporates deposited on the shelf in playas, sabkhas and lagoons; coincident "reef" and or grainstone shoals were deposited at the shelf margin; and thin and.

Sediment impacts differed between sites with mean sedimentation rates ranging from low to moderate (summarised in Figure 2).To determine terrestrial runoff impacts, the rate of clastic (non-carbonate) sedimentation was measured, detailed carbonate-clastic methods given brief, sediment traps (n = 3 site −1) were attached to the reef framework 50 cm above the substrate at 10 m water. Chemical Sedimentary Rocks Whereas clastic sedimentary rocks are dominated by components that have been transported as solid clasts (clay, silt, sand, etc.), chemical sedimentary rocks are dominated by components that have been transported as ions in solution (Na +, Ca 2+, HCO 3 –, etc.).There is some overlap between the two because almost all clastic sedimentary rocks contain cement.

These progradational carbonate sand sheets form as shoreline deposits, marine bars or tidal deltas on the seaward portions of carbonate platforms and mark the upper portions of shoaling upward sequences.

Rarely, clastic carbonate material is derived from older lithified carbonate terranes, in which case production of carbonate sediments is unrelated to basinal dynamics or paleoecology of the shelf (Mount, ). In this paper we introduce a previously undoc-umented style of mixed carbonate . In this system carbonate and siliciclastic sediments are separated by a boundary zone whose position on the shelf varies like the front between warring factions on a battlefield; mixtures of carbonate and siliciclastic sediment are confined to transitional mixing zones between the carbonate and siliciclastic fields (Mount, ; Doyle and.

Best known for the shelf-edge barrier system and the abundant reefs, the Belie shelf includes an equally diverse array of marginal-marine and carbonate-island environments, as well as a complete transition from quartzose nearshore sediments to pure carbonate deposits across the narrow shelf lagoon.

Shelf and upper slope sediments are a variable mixture of Holocene and late Pleistocene quartzose terrigenous clastic and bryozoa‐dominated carbonate particles.

Bryozoa grow in abundance to depths of m and are conspicuous to depths of m. Basically, the Belize shelf consists of a seaward reef-cay complex and a shoreward lagoon system. The mainland of northern Belize is a low karst surface. The adjacent northern shelf is shallow and is mantled by a suite of almost wholly carbonate sediments.

The southern Belize mainland is mountainous and drained by numerous streams transporting large volumes of clastic sediment seaward. The inhibiting effect that siliciclastic material has on carbonate-secreting organisms has lead to the generalization that sediments composed of mixtures of carbonate and siliciclastic material should rarely form.

However, many modern and ancient shelf deposits contain a spectrum of sediments that are of “mixed” composition. Belize shelf—Carbonate Sediments, Clastic Sediments, and Ecology.

Formation of Carbonate Sediments Sediment composition is fundamental in characterizing the depositional environment Grain size not necessarilya function of hydraulic regime Commonly is, but some carbonates behave like clastic sediments (e.g., grainstones, carbonate turbidites) Platforms, banks formed in situ: self-generating and self-sustaining.

The ‘carbonate factory’, where most carbonate sediment is generated, is typically located on the shallow, illuminated parts of the shelves. Conditions are ideal for the precipitation of carbonate sediment directly from seawater and for the growth of animals and plants that are the sources of aragonite and/or calcite skeletons (Figure 2F, G, and H).

Terrigeneous sediments that reach the continental shelf are often stored in submarine canyons on the continental slope. Turbidity currents carry these sediments down into the deep sea.

These. Sediment transport & deposition • Sediment is transported by wind, water and ice. Ice is a solid and so can carry sediment particles of any size, but wind transports only sand and smaller particles. The most prolific transport agent is running water.

The larger the particle size, the more vigorous the current required for transport. The continental shelf, continental slope and continental rise, collectively form continental margins, particularly where they form the trailing edge to continents. The sediments accumulating on these continental margins vary between siliciclastic and carbonate, with most areas accumulating siliciclastics.Sedimentary rock - Sedimentary rock - Carbonate rocks: limestones and dolomites: Limestones and dolostones (dolomites) make up the bulk of the nonterrigenous sedimentary rocks.

Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO3). Dolomites are mainly produced by the secondary alteration or replacement of limestones; i.Oceanography Water temperature and circulation, light penetration, oxygenation, and salinity have a direct and paramount bearing on carbonate production (James and Kendall, ).

carbonate production decreases sharply below 60 meters of water depth due to lack of the necessary light for carbonate fossils photosynthesis. carbonate production is greatest in the upper 10 meter of water .
