  abstract = {{T}he geochemistry of dissolved trace elements ({V}, {M}n, {C}o, {N}i, {C}u, {Z}n, {A}s, {R}b, {S}r, {M}o, {C}d, {S}b, {C}s, {B}a, {P}b and {U}) in the {U}pper {M}adeira basin, which constitutes the {B}olivian part of the {A}mazon basin have been investigated. {U}sing a statistical method (principal component analysis), the combined use of these geochemical data together with geological information on each watershed demonstrated the fundamental control of the substrate lithology on the trace chemistry of unpolluted surface waters within the catchment, at least in the {A}ndean part of the basin. {T}hree factors account for 87% of the variance. {T}he first factor represents the influence of solution of evaporite and associated deposits occurring in the {A}ndean {P}alaeozoic and {C}retaceous sections; the second represents the influence of the mining activities being carried out in the {T}aquesi basin; and the third, the influence of black shale products and arenaceousargillaceous rocks. {I}n spite of the occurrence of evaporite rocks in the {U}pper {M}adeira watershed which tend to mask the trace-metal signatures of other lithological formations, it has been possible to discriminate the sources of trace metals present in the {A}ndean and {A}mazonian {P}lain rivers.},
