A review of the origin and propagation of pans
A review of the much debated aspect of the origins of pans, dating from 1899. The theories relate to propogation, not the initiation of pans. Some pointers to the problems of initiation are presented. - (AJC)

Lunetteduine van Hakskeen- en Ethoshapanne

Lunette dunes of the Kakskeen Pan and Etosha Pan
The origins and development of thelunette dunes are related to the development of the pans. The material in the dunes originated from the pans and the inter-relationhip between the two is examined in the context of climatic changes in the recent

Quaternary palaeoenvironments of pans in central South Africa : palynological and palaeontological evidence
Various palaeontological remains have been found in springs, sandy lunettes and floor deposits at pans in South Africa. Analysis of two pans in the Orange Free State provides a more coherent Quaternary palaeoenvironmental reconstruction than before

L'unité granulitique des Iforas, constituée de matériel éburnéen, correspond à une grande nappe de socle pan-africaine dont la géométrie complexe s'explique par l'interférence de plusieurs épisodes de déformation.

Palaeoenvironmental reconstruction from near-surface pan sediments : an example from Lebatse Pan, southeast Kalahari, Botswana
This paper reports the results of the analyses of 3 cores, 1.8 to 2.6 m in length, taken from Lebatse Pan in southeast Kalahari. The sedimentary characteristics are compared with other core logs from the region, and an assessment is made

The origin and distribution of pans in the Orange Free State
The area covered by pans in the Orange Free State varies from nul in some parts to more than nine percent per quarter degree square. The highest incidence is found in the western parts of the province. Percentages exceeding 1,5 percent per unit area
are also situated to the east of Bethlehem. Factors which influenced and are at present influencing the distribution of pans, are soft bedrock formations, stream derangements by aeolian deposits, the presence of soluble salts in the sediments, precipitation
characteristics, the action of larger mammals, the more or less plainlike character of the terrain, and wind erosion. The latter is considered the most important factor and most pans in fact prove to be deflation hollows. At present wind erosion is not effective
in the eastern parts of the province and the presence of pans in that area can only be ascribed to a more arid climate in the past. (L'A.).

Thermo-topographically induced winds in the boundary layer over the Etosha Pan
Boundary layer winds over the Etosha Pan in Namibia reveal a diurnal oscillation. An analysis of this phenomenon is presented with relation to synoptic forcing and thermo-topographical forcing. - (AJC)

Soils and associated materials of some pan floors and margins in southern Africa : a review
A review of information on the occurrence, classification, properties and genesis of soils, pedogenic duricrusts and unconsolidated sediments covering pan floors and margins. A three-fold division based on climate was establisehd. - (AJC)

The article presents the life and creative output of Richard N. Coudenhove-Kalergi, the author of the Pan-Europe concept that brought together many of Europe's leading intellectuals in the inter-War period. The assumptions that underpinned the Pan

Processes of silicate karstification associated with pan formation in the Darwin-Koolpinya area of Northern Australia
The purpose of this paper is to describe sediments within a pan in northern Australia, where the geomorphological history is known and where water analyses have established the nature of the contemporary processes. The target was to examine in what
way and to what extent the sediments reflect the known history of the pan. Results of thin section microcopy and scanning electron microscopy with energy-dispersive X-ray are discussed.
