The report presents results of a detailed topographical and geological survey of a Libyan Desert oasis, including mapping procedures and traverses, descriptions of roads linking the oasis to the Nile and neighboring depressions, and measurements of elevations and water sources. It documents surface and subsurface geology—chalky and siliceous Eocene limestones, interbedded marls and sands, and fossil‑bearing beds with abundant nummulites—and interprets local stratigraphy and structural features such as synclines, escarpments and anticlines. Chapters describe settlement patterns, water‑supply observations and antiquities, and the text is supported by maps, sections and photographic plates that illustrate the field data and interpretations.
