文摘
- •
SKS splitting parameters (ψ and δt) are computed for Eastern Indian Shield.
- •
The mean ψ and δt for EIC are estimated to be 63° and 1.4 s, respectively.
- •
Mantle anisotropy in EIC is attributed to frozen Archean lithospheric anisotropy.
- •
Detection of a Pan-African suture separating Archean and Proterozoic terrains.
- •
δt = 1.4 s do suggest a contribution from anisotropy due to athenospheric flows.
