Magnetic disturbance events and quiet daily variation as recorded by the 1979 magnetometer array study in north-west India are analysed for evidence of electrical conductivity structures in the region. Contour maps of Fourier transform parameters are presented, and the disturbance event data are also reduced to sets of real and quadrature Parkinson arrows over a range of periods. A variety of conductive structures in the area are mapped, including some relatively shallow ones thought to be caused by sediments, as in the Ganga basin. More information is obtained on a major conductivity structure which strikes perpendicular to the Ganga basin into the foothills of the Himalayas; a second major conductivity structure is detected to lie to the west of the array area, and may be associated there with some aspect of the suture zone of India and Asia.
