The Western Margin is of critical importance for understanding the recent and active tectonics of the Nanga Parbat Massif. There are a variety of structures present, including rare segments of an early ductile contact between the Kohistan arc terrane and rocks of the Indian continental crust (which are indicated on the adjacent map). However, the margin is dominated by later structures. Some of these are associated with metamorphic fabrics and formed under ductile conditions while others formed under shallower burial conditions. These are marked by extensive fracturing and cataclasis, presumably associated with seismogenic faulting in the past. Taken together, these structures record the progressive uplift and unroofing of the area. You can visit a number of sites by navigating from the list below or the adjacent map, building up a picture of this polyphase deformation history and collecting kinematic data for your own structural analysis.
