In this context, the limonite horizon is developed at the top of the profile and consists of goethite, hematite, maghemite, gibbsite, and Mn-oxy-hydroxides. The topmost section of the horizon is the iron-cap (i.e., ferricrete) and it is commonly enriched with hematite and goethite (Samama, 1986, Freyssinet et al., 2005).
