Abstract

Using in situ analyses, this research investigated the weathering processes acting on primary minerals of basaltic pebbles embedded in a soil in a Mediterranean environment. The goal was to obtain data on the crystal chemical composition of the secondary minerals and evaluate how they contribute to the soil clay mineralogy. Micromorphological analysis focused on identification of the most significant mineral weathering microsystems and of the soil-features that connect them to the soil environment. In situ chemical composition was evaluated by SEM–EDS analyses and crystal chemical arrangement was defined by FT-IR and XRD analyses. Phase diagrams were used to illustrate and describe the evolutionary trends of chemical composition of the secondary clays
