A dioctahedral clay vermiculite in a soil from Saucelle, Salamanca
Published online by Cambridge University Press: 14 March 2018
Abstract
The <2μ equivalent spherical diameter (e.s.d.) fraction of the Ap horizon of a Brown Earth from Salamanca developed on Cambrian shales under a semi-arid climate with predominantly physical weathering has been studied. From X-ray diffraction results the mineralogical composition of this clay is: illite—70 per cent. kaolinite—10 per cent. and a “dioctahedral clay vermiculite”—20 per cent. The properties of the last mineral are detailed.
