  abstract = {{T}he results of a clay mineralogy study combined with major element geochemistry, strontium, neodymium and oxygen isotopes, and 14{C} {AMS} stratigraphy are reported for deep-sea gravity cores located in the {B}ay of {B}engal ({MD}77-180) and the {A}ndaman {S}ea ({MD}77-169). {E}psilon{N}d(0) and 87{S}r/86{S}r from {H}olocene and last glacial maximum ({LGM}) sediments of fifteen other cores have also been investigated to identify sediment sources and to estimate oceanic sedimentary transport. {T}he data show the contribution of three sources : (1) {G}anges/{B}rahmaputra rivers ; (2) {I}rrawaddy {R}iver ; and (3) sediment derived from the {W}estern part of the {I}ndo-{B}urman ranges. {T}he dispersion of the detrital material issuing from these sources has been constrained by the geographic distribution of {N}d and {S}r isotopic ratios. {T}he {LGM} sediments are characterized by a significant increase of 87{S}r/86{S}r, small changes in {E}psilon{N}d(0), and a general decrease of smectite/(illite+chlorite), which together imply a decrease in weathering intensity. {T}he increased 87{S}r/86{S}r are attributed to a decrease in chemical weathering, which should release preferentially 87{S}r during weathering processes. {I}n the {A}ndaman {S}ea sediments, smectite/(illite+chlorite) and kaolinite/quartz ratios combined with a chemical index of alteration ({CIA}*) indicate that the weathering intesity of the {I}rraddy {R}iver basin is mainly controlled by the summer monsoon rainfall intensity. {T}he wet summer monsoons increase vegetation cover in the plains and favor soil development by the production of pedogenic clays (smectite and kaolinite).
