Application of LANDSAT satellite imagery for iron ore prospecting in the western desert of Egypt

The author has identified the following significant results. The delineation of the geological units and geological structures through image interpretation, corroborated by field observations and structural analysis, led to the discovery of new iron ore deposits. A new locality for iron ore deposition, namely Gebel Qalamun, was discovered, as well as new occurrences within the already known iron ore region of Bahariya Oasis

Effect of Gamma Irradiation on Wheat Immature Culture Regenerated Plants

Abstract: The effect of gamma rays on grains of wheat (Triticum aestivum L.) irradiated with 150, 250, 350 and 450 Gy was studied on second generation (M 2 ) plants immature embryos culture callus growth rate, plant regeneration, agronomic traits and phenotypic and genotypic coefficients of four wheat cultivars. The results showed a highly significant effect between the four tested wheat cultivars i.e. Sids-1, Sakha-93, Sahel-1 and Giza-168 under different doses of gamma rays. The low dose of 150 Gy seemed to have a stimulating effect on all characters studied. On the other hand, the high doses caused significant reduction as compared to the control for all studied traits. The highest percentage of callus growth rate and plant height was obtained in Sakha-93. The interaction between gamma rays at 150 Gy and Sids-1 give a significant increase in callus induction percentage, plant regeneration, all growth characters, yield and its component as compared to control. Genotypic and phenotypes correlation were positive and highly significant between callus growth rate and grain yield per plant

Geologic interpretation of ERTS-1 satellite images for West Aswan Area, Egypt

ERTS-1 images of West Aswan area were interpreted in terms of geology, drainage, and structure. Twenty-two geological units were distinguished on ERTS-1 images in West Aswan area covering geological formations and erosional levels within some formations ranging from the Precambrian to the Quaternary. Apart from the distinction of Aswan monumental granite the investigated area shows very interesting exposures of sedimentary rocks ranging from the Cretaceous to the Quaternary. Of special interest is the delineation of the iron-ore member of the Nubian Sandstone and the phosphate-bearing formation. The tracing of the geological formations from south to north and the distinction of the varied geological units within the Pliocene and Quaternary, and the discussion on the origin of tufa are of particular significance. Also, the tracing on these images of major fractures and faults intercepting Aswan Dam Reservoir and their significance on the seepage and possible future development of diversion channels from reservoir is emphasized
