Jl. Boeglin et al., CHEMICAL AND MECHANICAL EROSION IN THE UPPER NIGER BASIN (GUINEA, MALI) - GEOCHEMICAL WEATHERING BUDGET IN TROPICAL ENVIRONMENT, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 325(3), 1997, pp. 185-191
Seventy-two water samples were collected in the Niger river at Bamako
(Mali) during the years 1990, 1991 and 1992. Analyses allow the determ
ination of the geochemical weathering budget, estimation of the rates
of chemical erosion, physical erosion and profile thickening for a tro
pical basin under rather dry climatic conditions. For comparison, the
same weathering parameters were determinated for the basins of the Ama
zon (Brazil) and the Chari (Chad).
