Aioun distribution and structural control It is not possible to determine alignment directions of aioun in the central Chott el Djerid. This was because of the lower number of aioun when compared to spring mounds. However the entire aioun field appears as a large lineament orientated NNE-SSW. If aioun are related to deep groundwater upwelling it should be possible to relate the orientation of the aioun field to the Alpine structural trends in the region. If there is little relationship between them then it might suggest that aioun are controlled by shallow, rather than deep, groundwater movements. The evidence relating the aioun field orientation to structural trends is at the present time somewhat circumstantial. The aioun field appears to be located at the end of the Chott el Fedjadj anticline. This anticline plunges to the west and is overlain totally by playa sediments of the Chott el Djerid about 8km before the eastern edge of the aioun field. Geological strata in the Djebel el Asker, to the north of the Chott el Djerid, curve southwards in the direction of the aioun field (Fig. 2) . If the southerly structural trend of the Djebel el Asker rocks is continued the aioun field falls along its course. Appealing though this relationship may appear it still does not explain why there is deep groundwater coming up to the surface along this trend line. It may be that the entire structure is related to the buried nose of the Chott el Fedjadj anticline but without an adequate sub-playa reconstruction this can only be a matter of conjecture at the present time. 6. CONCLUSIONS It has been shown that the detection of spring mounds and aioun on playas from remotely sensed imagery has many advantages over conventional ground survey both in terms of overcoming logistical and geomorphological aspects; and that it enables advantage to be taken of the shape and spectral characteristics of these features. A further major advantage of mapping the 611
