lateritization|ˌlætərɪtaɪˈzeɪʃən|
[f. laterite + -ization, rendering G. lateritisirung (now -ierung) (M. Bauer 1898, in Neues Jahrb. f. Min., Geol. u. Paläont. II. 203).]
= laterization.
1903Geol. Mag. Decade IV. X. 62 That the formation of laterite is a mere question of average temperature seems unlikely, for lateritization is very prominent at elevations of 6,000–7,000 feet..in South India, where the temperature varies very little above or below 60° F. 1920Geol. Mag. LVII. 212 The depth of lateritization was so great on the right bank of the Congo at a height of about 500 O.D. that [etc.]. 1934Discovery July 202/1 Lateritization (silica leaching) may be considered as the reverse of podsolization (iron and aluminium leaching). 1966McGraw-Hill Encycl. Sci. & Technol. VII. 406/2 The resulting concentrations of iron and aluminum oxides sharply differentiate lateritization from temperate-climate weathering in which the end product is largely clay minerals (hydrous aluminum silicates).
Hence (as a back-formation, or after G. lateritisi(e)ren) ˈlateritize v. trans., to convert into laterite; ˈlateritized ppl. a., -itizing vbl. n.
1911Geol. Mag. Decade V. VIII. 509 These five rocks..were probably formed in situ under conditions in which the lateritizing processes were not pushed to a finish. 1920Geol. Mag. LVII. 214 Certain inclined bands in the norite have been thoroughly lateritized for many yards along their outcrop, and seams of magnetite in them..run practically unaltered from norite into laterite. Ibid. 212 The lateritized portion was more readily removed by erosive agencies, and the masses of unaltered rock were left standing in relief. 1970Nature 23 May 693/2 The southern half of Western Australia is an old, slightly dissected, lateritized land surface dating from the middle or late Tertiary. Ibid., The Giles Complex of mafic and ultramafic igneous rocks..has been lateritized. |
