Similar provenance for the JT and PRT sediments are also inferred from the multi-
element geochemistry (Table 2). Except for few elements, both JT and PRT have comparable
major element concentrations. Higher concentrations of Br (77 ppm), Na2O(5.20%) and
Fe2O3 (5.09%) in the JT deposits are indicative for themediumof transportation and sorting of
different minerals during deposition. Higher content of Br (8-fold) in JT than PRT reflects the
sediment transportation by the incoming sea water (e.g. Peters et al., 2001). Similarly, higher
Na2O reveals the presence of halite (NaCl) precipitated from the evaporating of sea water.
The higher concentration of Fe2O3 in JT is also supported by the fact that tsunami deposits
show higher abundance of amphiboles, pyroxenes and garnet.
