We seek to determine the strain field which has accumulated in the Indian Shield due to the continental drift of Gondwanaland. We have used a method which involves the calculation of the 2D isostatic coherence response function between Bouguer gravity and topography as a function of azimuth by way of multispectrogram analysis. The average coherence is maximum consistently in the Indian Shield in a direction, which is at an angle of 45° to the major trend of suture zones within the shield, a result which is in good agreement with the strain inferred from absolute plate motion (APM) in a hot spot reference frame. This directionality of mechanical plate weakness suggests that all paleostress fields were erased due to the movement of the Indian plate during the Himalayan orogeny.
