The north-western segment of the Karakoram Fault is far less disputed than other areas. It terminates in the extensions of the Miuji Basin, in the Pamir Mountains, along the border between Tajikistan and Xinjiang provinces. In this north-western segment, the Karakoram Fault currently has predominantly normal fault motion, and right-lateral strike-slip offset. The slip in this section of the Karakoram fault is measured to be approximately 150 km, as measured by the offset of the Aghil formation. The Aghil formation is a fossiliferous carbonate formation. Before entering the Pamir region the Karakoram fault is believed to split into two distinct faults. These faults are the main Karakoram fault itself, and the Achiehkopai fault.
