White, D.A., 1954. Some observations on laterites in the Northern Territory. Record  1954/013. Bureau of Mineral Resources, Geology and Geophysics, Canberra.

Abstract

In the Northern Territory laterites are formed in situ as: (i) an illuvial soil horizon; and (ii) a chemical lake laterite deposit. The end product of extensive weathering processes of certain favourable beds is considered by some to be a true mature laterite, whereas others believe it is merely a duricrust. The denudation of laterite and transportation, deposition and cementation of the fragments with other rock fragments result in a detrital laterite deposit. Water-rounded rock fragments in the detrital laterites are readily coated and cemented with iron oxides and resemble the pisolites in the ferruginous zone of the lateritic profile. This similarity results in an exaggeration of the true extent of laterization. The similarity in environmental conditions between the process of precipitation of uranium minerals and laterization is discussed. True mature and detrital laterites are illustrated by photographs.
