Geology
An iron-rich lateritic conglomerate, formed from the decomposition of underlying rocks by subsurface chemical weathering. Also attributive.
1892 The Jrnl 20 Sept. 2A few months ago it was discovered..that large beds of Ou Klip (honeycomb gravel rock) on the farm were literally saturated with mercury.
[1926 A.L. Du Toit Geology S. Afr. XVII. 361In many parts of South Africa a peculiar ferruginous material can be observed resting either directly upon the decomposed underlying rocks or more usually with the intervention of sandy clays..Called by the Dutch farmers ‘ouderklip’ or ‘ouclip’, it is supposed by them to represent a lava flow of great antiquity, whereas on the contrary it is generally the youngest formation present.]
1940 Min. Resources of Union of S. Afr. (Dept of Mines) IV. 458There are many types of laterite or ‘ouklip’ in this country. The harder types of conglomerate ouklip generally form a very good basecourse for bitumen...Some types of soft conglomerate ouklip which contain an appreciable quantity of sandy soil binder generally yield satisfactory sand-clay bases...The pebble type ouklip..consists mostly of fairly hard lateritic pebbles and soil binder.
1955 J.H. Wellington Sn Afr.: Geog. Study I. 289In the western highlands of Natal, Pentz recognizes a third grassveld type..in which the infertile sandy soils, underlain by ‘ouklip’ (i.e. pirolitic ironstone) produce a poor type of veld.
1958 S. Cloete Mask 186The soil changed to oaklip. The veld changed.
1961 M.M. Cole S. Afr. 87The weathering processes..result in the formation of soils comprising an A horizon of some 12 to 24 inches of friable sand..overlying a B horizon of mottled clayey-sand containing many ferruginous concretions which in the lower part are cemented to form a hardpan called ‘ouklip’.
1970 Memorandum of Agreement. (A.R. Whiteley & Co.) Sept.No allowance is included for excavation in abnormal circumstances such as waterlogged soil, hard or soft rock, shale, ouklip or ground containing boulders.
1973 Farmer’s Weekly 9 May 65The soil is poor being yellow turf about 0,75m deep on ou klip conglomerate. The presence of ‘ouklip’ layers just under the surface of a soil means poor drainage and gives rise to ‘drowning’ of plants in wet seasons.
1983 S. Afr. Garden & Home Mar. 126The plants..probably have not been able to send their roots out into the outklip...They may also be waterlogged — as the water would not drain away in the outklip.
1988 D. Hughes et al. Complete Bk of S. Afr. Wine 55Kroonstad has a sandy top layer with an iron-bearing pan of peculiar hard, nuggety forms known as ouklip, just above the clay.
An iron-rich lateritic conglomerate, formed from the decomposition of underlying rocks by subsurface chemical weathering. Also attributive.
