| | Abstract | | to formation of seafloor massive sulfide (SMS) deposits, which have potential for mining. Controlled-source electromagnetic (CSEM) surveys can be used to map SMS deposits due to the low resistivity features compared to surrounding sediments. 2D inversion of CSEM surveys have been used for exploration of SMS deposits. However, 2D inversion often images artefacts for SMS deposits because the deposits have 3D structures. Here, I have developed 3D CSEM inversion software to image resistivity structures of the deposits. A feasibility study of 3D CSEM inversion was conducted to determine the ability to map SMS deposits. We found 3D CSEM inversion is useful for mapping resistivity structures of SMS deposits. |
