摘　　要：Tangi Mahi-par is a fault valley from previews geological period (Pleistocene) where the Kabul basin was a lake and occupied by water, and after the formation of Tangi Mahi-par fault valley, water was drained from this way. Therefore, this research is essential to elucidate the different rocks types and structures, with no or scarce previous research’s in this mountainous area. The main objective of this study is to selected rock type, rocky structures and different sizes of river sediments transported by rivers discharge from the previous geological periods. There are different types of sediments, terrace remnants, rocks and geological structures which are generally consist of Limestone and Gneiss, where the limestone is likely belonging to the Thythes ocean remnants in Afghanistan and contains Ammonites fossils. In some parts volcanic breccias, it shows the old volcanic eruptions, Stalactite and stalagmite Carbonitic sediments related to limestones are also present there. In addition, there are different types of geological structures such as Anticline, Syncline, dyke, Sill, Apophysis, Graben and Horst. Unconformities and horizontal layers related to Khengal and Cottagay series passing from this area are located one by another.Tangi Mahi-par is a fault valley from previews geological period (Pleistocene) where the Kabul basin was a lake and occupied by water, and after the formation of Tangi Mahi-par fault valley, water was drained from this way.
