Karakoram fault system

127: 161:. Another suggestion is that the Karakoram fault is offset at least 500 km as measured by the offset of late Paleozoic granites in the Kunlun batholith. Most researchers tend to agree with the lower slip estimates. A major obstacle in measuring the total offset along the fault is in deciding what is actually a part of the fault and which faults are separate. Currently some researchers believe that the Karakoram fault merges and terminates into the Indus-Yalu suture zone at Mount Kailas. Other researchers also add the Gurla Mandhata detachment, in the South-Eastern segment, to the fault. 31: 196:
northern approximately 1 km wide area of the fault, and contains listric normal faults. The Gurla Mandhata fault system is thought to be encompassed within the Karakoram fault system at its southern tip, which cause the southern tip of the fault to be approximately 36 km wide. Exhumation along the Gurla Mandhata detachment, which is a low-angle normal-fault system, suggest that the faults have allowed for between 36 and 66 kilometers of slip.

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

had been offset 1000 km dextrally along the Karakoram Fault based on mapping in the central Karakoram, in nearby Ladakh-Zanskar, and in south Tibet. Some researchers suggest that this might be incorrect due to associating granite that was never part of the same batholith. Others researchers work

Most people agree that the South-Eastern portion of the fault merges into and parallels the Indus Suture Zone in South West Tibet. The southern segment of the Karakoram Fault shows that only 120 km of dextral motion is evident from offset of geologic features, such as the
