Caractrísticas mineralógicas de la Fracción inferior a 2μ en dystrandepts (II)
The mineralogical composition of the clay fraction (minus-two-micron) of three soils profiles, has been studied by X ray diffraction and I. R. absorption techniques. Allophane is the most abundant mineral. The kaolin group is represented, mainly by halloysite as accompanying mineral. Quart is present mainly in the more superficial soil horizons. In the clay fraction of these soil profiles, primary minerals have sometimes be found (felpars, pyroxenes, hematites, etc,) but they use be present in a much lower proportion than in other andosols of the Canary Islands.
