| Abstract: | The authors interpreted a major lineament in Ladakh region on LANDSAT imagery and named it Nubra-Gartang superlineament, after the two livers along which it is aligned for a considerable distance. The superlineament trending NW-SE, extends for a distance of 750 km from the Afganistan border to southern Tibet. Structural and geomorphic evidences indicate that the lineament is perhaps still active and represents a dextral strike-slip fault. The fracture pattern and other tectonic elements suggest that a ‘suture’ zone is expected further to the north of this line in the Pamir region and the so called ‘Indus suture zone’ may be only a sister fracture to this superlineament. Occurrences of Quaternary volcanics along the superlineament are not ruled out and as such the zone offers a favourable locale for associated mineralisation. |
