Plinthite
WebbPLINTHITE is an iron-rich, humus-poor mixture of clay with fine quartz. What are Plinthic soils? Plinthosols are soils with ‘plinthite’ a firm but soft, ironrich, redmottled clay, made up of a humuspoor mixture of kaolinite, quartz and other constituents that irreversibly hardens to petroplinthite when exposed to repeated wetting and drying. Webbthe eluviation horizon. Gleyic soil properties and/or plinthite are common in Acrisols in low terrain po-sitions. Mineralogical characteristics Acrisols have little weatherable minerals left. The contents of Fe-, Al- and Ti-oxides are comparable to those of Ferralsols or somewhat lower; the SiO2/Al2O3 ratio is 2 or less. The clay fraction ...
