The concentrations of Br and I in marine sediments have been used to categorize the sedimentary environments of different
coastal regions of the world with respect to organic matter contents. The present study uses the concentrations of Br, I and
P20S of different marine settings as a new proxy to interpret the depositional environments. A total of 150 coastal lagoon sediment samples (suspended sediments, surface sediments and sediment cores) were analyzed for Br, I and P20S concentrations
by X-ray fluorescence spectrometry. They were compared with the Br, I and P20S concentrations of the 2004 Indian Ocean
tsunami sediments. Sediments from various sources are separately clustered in I-Br plot and a trivial negative correlation
is found for the whole plot. A similar correlation pattern exists in the I-P20s diagram. This correlation is explained by the
distribution of marine plants (higher and lower) in different sedimentary environments of the coastal profile. Therefore, the
concentration of I and its relation to P20S can be used as a tool to identify sediment depositional environments in marine
settings. |
