Evidence for anisotropy in the super-thick sedimentary basin under the northern Bay of Bengal is presented. Surface wave group velocity data given by Brune and Singh (1986) is better fit by an anisotropic model than an isotropic one. This lends support to the hypothesis that the mid-crustal rocks are metasediments and that the section of sediments and metasediments is more than 20 km thick.
