The sand fraction was dominated by quartz in all horizons. Due to its resistance, quartz is commonly the most abundant mineral in the sand fraction of tropical soils, as it endures the long and intense weathering periods while other less resistant minerals are dismantled (Kämpf et al., 2012). Diffractograms showed that quartz was much more abundant in B and A horizons, in both silt and sand fractions.
