This paper presents the results of stratigraphic excavation and soil studies carried out at Mograt Island, the largest of the Nilotic islands in Sudan. Due to its restricted insular environments, Holocene alluvial deposits were observed to be interlocked with archaeological remains of different periods, allowing for a combined chronostratigraphic approach to study both cultural and climatic events. To better understand the environmental context through soil components and pedological features at a microscopic scale, soil block samples were accordingly collected and studied by the application of soil micromorphology. This approach provides insights into the history of Nile terrace aggradation through the suspension of Nile sediment loads under stillwater conditions as well as of the periodical establishment of shallow water pools at the islands’ plateaus by the surface run-off from local rains. Since these patterns vary significantly from the present situation, they offer a key to the scenario in which specific early agricultural and animal herding practices evolved.

The investigation of geology, stone implements and pottery presented below was performed in 2004 during works conducted by mixed american-egyptian mission at Heraconpolis archaeological site. The geological examination documents that the site was located on a dry, big delta of big wadi, coming from west into Nile Valley. This location means that while the site was functioning at phases Nagada II and III mentioned wadi did not conduct water i.e. climate was very dry. The investigation of present geological phenomena shows continuous growth of salinity of the soils at tested area. The investigation of stone implements discovered at two examined archaeological trenches confirmed the presence of various rocks, chipped flint implements as well as grinders. These objects were discovered at two depths representing various archaeological layers. Examination of pottery showed advanced technologies of preparation of ceramic mass as well as technology of firing. Data obtained from computer analyses confirm differentiation of tested ceramic masses.

Salinty of soils is the factor leading to the limitation of agriculture. Due to the reduction of suitable fields farming is also reduced. As a consequence farmers have to leave farms. This problem is specially important in Egypt where cultivated land is limited to the Nile Valley. A mineralogical and geological investigation of this phenomenon is conducted at Heracompolis and surrounding areas showed the presence of the following minerals as white salty coatings covering the surface of local soils: The absence of natural floods of Nile stopped due to the construction of the Aswan Dam is the reason for the continuous elevation of the degree of the salinity of soils. Evapotarion of water used for agriculture cannot be prevented but the process of mineralization has to be stopped if Egypt wants to avoid reduced food production.
