Study on River Terraces in Upper and Middle Parts of Kabul Sedimentary Basin, Afghanistan

Hafizullah Rasouli ^[2]

Abstract: This research cariedout study of heavy and light minerals in Kabul, Loger and Paghman rivers terraces, which is located in upper and middle parts of Kabul basin in Afghanistan. The younger sediments of upper and middle parts of Kabul have different size and thickness, in upper part of Kabul is morethan consolidated Gravels, belonging to Quaternary but the middle basin of Kabul is consist of sandston, gray, white green and brown Marble. This research is therefore essential to estimate the different size of river sediments, with no or scarce previous researchs in this basin. This paper provides the results of transported at different size and type of sediments carried by rivers discharge from snow covered areas of upper and middle parts of Kabul basin in Afghanistan. The main objective of this study is to selected different size and type of river sediments transported by Kabul, Loger and Paghman rivers discharges in upper and middle parts of Kabul basin for the previous geological periods. From analysis, in middle terrace of Paghman river, Granaite 87 %, Quarsite 9 % and Gnaize 4 %, bigger size is 8 10 cm and smaller is 7 7 mm. in lower terrace of this river, Granite 77 %, Quarsite 22 % and Gnaize 1 %, bigger size is 9 9 cm and smaller is 6 7 mm, in upper terrace of Maranjan hill, metamorphic rocks (pholith) 84 %, Quarsite 13 % and Grainte 3 %, bigger size is 7 8 cm and smaller is 6.6 7 mm, in the middle terrace of Nawruzabad hill, Pegmatite 1 %, Sederite 10 %, Quarsite 36 % and Gniaze 53 %, the bigger size is 7 10 cm and smaller size is 6.5 7 mm, in the upper terrace of Polycharkhy hill, Limestone 2 %, Green schist 5 %, Gnaize 93 %, bigger size is 9 10 cm and smaller is 6.5 6.8 mm, respectively.
