AB The trace elements of the quartz mineral, in the fine sand fraction (50 - 250 μm) from two Orthent soilsfrom Sierra Nevada have been studied. Fe3+ is the most abundant trace element, followed by Al3+, and K+,Ca2+, Na+, Mn4+, Mg2+ and Ti4+ in smaller quantities. The heteroelectric substitution in the Si4+ tetrahedraby Fe3+ and Al3+ has been evidenced, generating a deficit of positive charge which is compensated by theentrance in the crystalline network of K+, Ca2+, Na+ and Mg2+. These substitutions are more abundant inthe edges of the grains than in the centres of the same ones; from what a decisive paper of the soil solutionin the mobility of these elements is postulated. We propose a process of alteration of the quartz in the soilenvironment
