استعمال الإحصاء الجيولوجي في إعداد خارطة لمعادن الرمل في بعض مناطق الفرات الأوسط

الملخص EN

This study was carried in some of the Middle Euphrates areas in the provinces of Babil, Najaf and Karbala, for the purpose of knowledge seporated prevailing sand and the weathering status exposured by it the minerals within the studied area.

Sites for eight pedonats were chosen and the surface samples between tow pedonats was identified using satellite image of the moon for Landsat 7 and these sites were the University of Babylon, alkifl, alshla mosque, Alhaidariya, agricultural city of Al-Hussein, Karbalaa University, alhindia Horticulture and Hilla, which were identified its coordinates using a GPS device, the pedonats of the study were characterized and the soil samples were obtained from each vista for laboratory analysis.

Laboratory side involerd estimate minerals separated soft sand, however in desktop side, the GIS9.3 program was used to draw a map that show the distribution of each minerals in the studied area through the use of Kriging property.

The results showed that the sovereignty of the minerals separated heavy sand was of Opequse, chlorite , Biotite, however, light minerals sand sovereignty was for mineral quartz, calcite, evaporites, The weathering guide values were low throughout the study area.
