Abstract: This study aims to examine the stratigraphy architecture and sedimentology of the Gaza Strip, from the Pleistocene to the Holocene age. The study area is restricted to the Gaza and Middle-to Khan Younis Governorates of the Gaza Strip. The Gaza Strip is a southwestern part of the Coastal Plain of Palestine. To accomplish these aims, data collected from field observations of outcropping rocks, boreholes, and hydrogeological wells has been used. The logging of selected sections paid attention to genetic facies associations.
