ABSTRACT
The Bunthang sequence constitutes the sedimentary record of the late Cenozoic infilling of the Skardu basin, an ~250 km2 intermontane basin within the Karakoram Himalaya mountains of Pakistan. Previous palaeomagnetic studies of the 1.24 km thick Bunthang sequence identified only reversely magnetized strata and were unable to collect samples from a 330 m thick interval in the middle Bunthang sequence. Although chronometric resolution of these data was not good, the age of the Bunthang sequence was bracketed between 3.2 myr and 0.73 myr. Four additional palaeomagnetic sample sites were established in the middle Bunthang and basal upper Bunthang sequence to supplement the 72 reliable sites previously established in the upper and lower Bunthang sequence. One of the sites in the middle Bunthang sequence is normally magnetized. The remaining 75 sites are reversely magnetized.
