Biogenic matter

In the solid runoff of other rivers, regulated owing to the construction of reservoirs, biogenic supply has a greater significance. While in the near-shore zone at low depths the proportion of the biogenic matter ranges from 30 to 50% of the total sediment, the proportion of coquina and detritus in the sediments of the central zone of the northwestern part of the sea reaches 80% and more. [Pg.60]

Figure 3t. Isotope age functions of organic carbon (Corg) over 3.8 billion years of recorded Earth s history as compared with the isotopic composition of their progenitor substances in the present environment (marine bicarbonate and biogenic matter of various parentage cf. Right panel). Isotopic compositions are given in values, indicating either a relative increase (+j or decrease (—) in the C7 C ratio of the respective substances (in per mil difference) as compared to that of the Pee Dee Belemnite (PDB) standard with =...

Since apatites serve as a row material for P fertilizer production, the impurities of heavy metals are the source of great pollution of agroecosystems. In general, the major phosphorite deposits are of marine origin and occur as sedimentary beds ranging from a few centimeters to tens of meters in thickness. The biogenic matter produced in water column settles to the sediment surface and decomposes, releasing P04- to the sea water and pore water. [Pg.125]
