Analysis of site formation processes is a field of research which can be enhanced by means of computer applications. In this paper, the authors suggest the use of image analysis applied to the study of soil micromorphology and to archaeological deposits, aimed at the qualitative and quantitative evaluation of the soil components. The presence of specific devices and software allow these problems to be faced in a quick and user-friendly way, thanks to the Windows interface. The case study looks at the Uan Afuda cave in the Tadrart Acacus (Libyan Sahara), and the sediments related to the Mesolithic occupation (8900-8000 BP), which is characterised by vegetable accumulations alternating to ashes layers. The application let us weigh the specific components of the layers, from both a microscopic (soil thin sections) and macroscopic (excavated stratigraphic section) level. Consistence of results opens up new perspectives of analysis for the comprehension of the formation processes in arid environments and for the cultural problems linked to them.
