Carbonate crusts developed on basalt were studied at Tazouta in the Moroccan Middle Atlas. The chosen representative weathering profile is 2.8 m thick and is composed from base to top of a fresh basalt overlain by a coherent saprolite, a friable sapr

The calculation of the mass transfer attending lateritic weathering was carried out by Brimhall et al. in 1991 by an approach that assumes immobility of one or another element, especially Zr. This calculation is flawed because: (1) Zr is mobile (as e

We have analyzed samples of a 15 m thick profile weathered from the Madeira granite, located in the Pitinga basin river, north of Manaus, in the state of Amazonia, Brazil. This profile consists essentially of a yellow-red saprolite covered by a soil.

Unheated natural mixtures of manganite and secondary pyrolusite, from the same lateritic manganiferous sequence, were studied in different orientations by high-resolution transmission electron microscopy (HRTEM), electron diffraction, and energy-disp

The effect of different storage times in glutaraldehyde was evaluated in porcine valve heterografts prior to implantation. Histological, scanning and transmission electron microscopy examinations were performed on 6 glutaraldehyde-treated porcine aor

The speciation of As and Fe was studied during the oxidation of Fe(II)-As(III) solutions by combining XAS analysis at both the Fe and As K-edges. Fe(II) and As(III) were first hydrolyzed to pH 7 under anoxic conditions; the precipitate was then allow

Intellectual and behavioral abnormalities, non-psychotic psychiatric disorders, and drug abuse are sometimes present in adolescents who later develop schizophrenia. We followed a population-based cohort of adolescents with baseline assessments of int

The term «bauxite» was introduced by Berthier (1821) and refers to rock samples belonging to the laterite type. Lateritic bauxites have been studied by many, mainly by prospection and exploration geologists, and by geologists, soil scientists and g

Three successive stages of crystallization (magmatic, late-magmatic and hydrothermal) were petrographically, mineralogically and chemically distinguished in the Juquia carbonatite (southern Brazil). The first stage corresponds to crystallization of m

Physical and chemical factors controlling natural weathering processes of pyroxenes through the formation of secondary minerals are reviewed. It has been shown that besides climate, mineralogy, and petrology of parent rocks, mineralogy and structural
