Abstract
Quaternary fluvio-lacustrine deposits in the currently arid Egyptian desert can be used as indicator for the pluvial phases in the Sahara and a record of climatic change. Some fossil springs formed from tufa deposits were found along the edge of the Libyan plateau scrap in Dakhla Oasis, Egypt. At least eight major episodes of fossil spring mounds were discovered near El Gedida village, Dakhla Oasis, most of tufa mounds were deposited as a part of fluvial system, characterized by terraced, vegetated pools and accumulated tufa dams and separated by low waterfalls.
 This paper depending upon geomorphologiacl, sedimentological and remote sensing methods, in addition to extensive field surveying, mapping and sampling for C12, C13 and C14 AMS dating, to develop a Pleistocene climatic chronology as paleo spring mounds are particularly amenable to AMS dating techniques for both tufa sediments as well as current spring hot water to define the sources of its acidify-gas water, for more understanding of the desert pluvial events, and the time of human migration from this area of the western desert of Egypt, and finally it would also help to define water sources of the current hot springs and whether renewable sources or is it an ancient fossil water.
