  abstract = {{S}edimentation rates were estimated in a {C}entral {A}mazonian {B}lack-water inundation forest. {S}ediment deposition on the forest ground, remote from the river bed, during an annual flood period, is of the order of 1 to 10 tons per hectare, depending on water depth and duration of flooding. {T}he sediments consisted of fine organic matter, kaolinite, quartz sands and biogenic particles of silica. {T}heir genesis and deposition depend on the interplay between pedogenic, limnological and biological processes. {S}ediments derive primarily from the materials leached from the soils. {C}lay soils are the main source of dissolved silica, and the sandy soils are the main sources of organic compounds and mineral particles. {T}he physical sedimentation of particles as quartz and grains only occurs in the upper reaches of the studied river. {I}n the flood plain, the sedimentation is due to the coagulation and deposition of combined mineral particles and humic substances, and to the biological precipitation of the silica leached from the soil by sponges.
