Qualitative Analysis of Audio Magnetotelluric (AMT) Data using Phase Tensors: A case study from Dhanjori Basin, Singhbhum Craton, India

Dhanjori Basin, a part of Singhbhum Craton, Eastern India shows characteristics of the Greenstone belt and is a great source of sulphide mineralization in the area. AMT survey was conducted to infer the metallogeny of the area. Regional MT response is distorted by the presence of near surface intrusive bodies, but phase remains unaffected. Thus, Phase tensor approach has been utilized to identify the near surface conductive bodies and to have an idea about the regional dimensionality of the area.
