Abstract
Analysis by energy dispersive X-ray spectrometry (EDS) of cutans linking grains in coarse-textured duric horizons with plectic fabrics indicated that Al-organic material was a component of the cement. (Al, Fe)-organic material occurred in voids near the upper surface of duric horizons with porphyroskelic fabrics but EDS was not useful in detecting the cement of such horizons. Ground (2 mm) sandy loam C horizon material from a soil with a dense duric horizon was cemented strongly by as little as 0.1% (Al + Fe) precipitated with Na2 SiO3. Results of this and previous studies suggest that various combinations oa Al, Fe and Si hydrous oxides and humified organic matter act as cementing agents of duric horizons and that very little cement is required to indurate closely packed materials.This publication has 0 references indexed in Scilit:
