The geology, origin and age of the ground water supplies in some desert areas of U.A.R.

- In a joint enterprise, the ground water supplies in some Oases in UAR (namely El Kharga, El Dakhla, El Baharia and Siwa), in Wadi El Natrun (to the west of the Nile Delta), in Ayoun Mousa (West Sinai) and in some places along the Mediterranean Littoral, have been investigated. According to the dating of the water by the C14 method, the age of the artesian water from the Oases is between 25,000 and 40,000 years and the origin is obviously from rain water which fell and infiltrated within the "Nubian Sandstone" layers, occupying almost entirely the southern portion of the western Desert (the water underwent some evaporation before it disappeared in the subsurface as indicated from the loss of the 016). This process took place during one or more of the Pluvial periods which followed (and were not coincident with) the last "Würm" eustatic lowering of the Mediterranean. No infiltration water have presumably recharged the layers in question, so almost entirely fossil water reserves are tapped at present. The quantities of such reserves are unknown. More ancient waters, however, may be expected to the north of El Kharga and El Dakhla Oases. Such waters may- to their greater portions - enter these two oases from that direction. On the other hand, little or almost no water is expected to feed the reservoir from the opposite direction.

Environmental isotope data in western Thessaly valley, Greece, use of mathematical model for quantitative evaluations with tritium
Bryan R Payne
- The present paper deals mith the results of an environniental isotopic study in western Thessaly valley, carried out during the period 1968 - 1971. The isotopes used are 18O, D, Tritium, 18C and 14C. By the interpretation and evaluation of these resiilts useflil informations as regards the soiirce of recharge, the recharge mechanisrn and the dynamics of the flow system of the valley are provided.
