The clay mineral composition of two "terra roxa estruturada" (TRE) soils occurring in the tropical rain forest and tropical forest(savannah transition zone, and a reddish brunizem in the savannah(semi-arid transition zone was studied comparatively in the southeast Amazon region. Kaolin mineraIs were dominant in these soils, and hematite and goethite were found in the clay fraction. A small amount of 2 : 1-type clay minerais was found in two soils. The mineral composition of the clay fraction in the TRE soils was hardly influenced by the difference of the meteorological factor or their water condition in this region, and this factor should not control the influence of parent materiais derived from basic rocks. The TRE soils were developed under the condition of laterite genesis, and were regarded claymineralogically as a kind of the lateritic soils. |
