1936 U.S. Dept. Agric. Misc. Publ. No. 229. 22 The laterization process is, perhaps, more strictly a geological process than one of soil building.
1938 U.S. Dept. Agric. Yearbk. 973 The soil-forming process called laterization is essentially the progressive hydrolysis of rock minerals, and its full development results in their conversion to silicic acid, aluminum hydroxide, and iron hydroxide or their more or less complete dehydration products—the Laterites.

1967 M. J. Coe Ecol. Alpine Zone Mt. Kenya 76 The clays show a certain number of darker stratifications but, due to the low temperatures, there are no signs of laterisation.
2005 R. J. Schaetzl & S. Anderson Soils xii. 393/1 Accumulations of Fe in soils are due both to residual accumulation (latosolization) and to processes that involve transfers of Fe (laterization).
